10 возможных юзкейсов (способов применения методик RAG из представленного курса) к проекту Mercury Bot — профессиональному боту-помощнику в сфере трейдинга.
Ниже приведены 10 возможных юзкейсов (способов применения методик RAG из представленного курса) к проекту Mercury Bot — профессиональному боту-помощнику в сфере трейдинга. Каждый сценарий демонстрирует, как механика поиска и генерации (Retriever Augmented Generation) может усилить функционал бота и предоставить пользователям более релевантные и детальные ответы.
1. Глубокий анализ пользовательских данных
Что даёт RAG:
- Позволяет “подтягивать” актуальную информацию о пользовательском портфеле, сделках, исторических данных.
- Векторная база (например, Chroma DB) может хранить подробную статистику пользователей, а генеративная модель будет выводить аналитические инсайты.
Пример:
- Пользователь задаёт вопрос: «Как изменилась доходность моего портфеля за последние 3 месяца?»
- RAG-система находит соответствующие данные в базе (ретривер), затем модель формирует понятное объяснение динамики.
2. Контекстуальные подсказки при формировании торговых стратегий
Что даёт RAG:
- При запросе торговой стратегии, Mercury Bot может искать векторизованные фрагменты обучающих материалов, статей по техническому анализу, исторических отчётов, чтобы обогатить ответ конкретикой.
Пример:
- Пользователь: «Посоветуй стратегию на основе моих прошлых сделок и текущего состояния рынка».
- RAG подбирает релевантные исторические записи, анализирует результаты сделок и выстраивает персонализированную рекомендацию.
3. Автоматизированные отчёты с релевантными вставками из внешних источников
Что даёт RAG:
- Позволяет подгружать свежие новости, аналитику из финансовых PDF-отчётов и статей, хранящихся во внутренней библиотеке.
- Модель генерирует автоматические отчёты с прямыми цитатами и ссылками на источник.
Пример:
- Ежедневный отчёт: Bot самостоятельно “прочёс” последние новости от Bloomberg, оценивает их значимость и генерирует финальный обзор для пользователя.
4. Быстрый поиск ответа в базе знаний или FAQ
Что даёт RAG:
- Обеспечивает прямые ответы на вопросы пользователей по обучающим материалам Mercury Bot (инструкции, гайды, документация).
- Сокращает время на ручной просмотр документации, выдавая точные фрагменты.
Пример:
- Пользователь: «Как настроить уведомления о резком скачке цены в моём портфеле?»
- RAG ищет нужный раздел из мануала и моделирует понятную инструкцию.
5. Персонализированные советы с учётом исторических паттернов
Что даёт RAG:
- Генеративная модель анализирует исторические паттерны сделок конкретного пользователя и предлагает, какие инструменты могут подойти под текущую рыночную ситуацию.
Пример:
- При вопросе: «Какое соотношение акций и облигаций выбрать, учитывая мои риски?» система ищет прошлые паттерны риск-профиля пользователя, сравнивает с рыночными трендами и выдаёт обоснованное распределение.
6. Сложные финансовые вопросы и интеграция стороннего контента
Что даёт RAG:
- Приходит на помощь, когда нужно учесть внешние финансовые отчёты, годовые отчёты крупных компаний и т.п.
- Модель извлекает нужные факты (даты, цифры, проценты) и подаёт их в сжатой форме.
Пример:
- «Как повлияют финансовые результаты Microsoft за последний квартал на мои акции MSFT?»
- RAG находит нужную информацию в загруженном годовом отчёте Microsoft (PDF), анализирует ключевые метрики и предлагает вывод.
7. Расширенные подсказки для обучающих целей
Что даёт RAG:
- Подтягивает фрагменты уроков, курсов по техническому анализу, фундаментальному анализу, risk management и т.д.
- Позволяет пошагово объяснить новые концепции, используя внутреннюю базу обучающих материалов.
Пример:
- «Объясни разницу между SMA и EMA на моём последнем графике?»
- RAG извлекает релевантные объяснения из учебного раздела, объединяет их с реальным графиком пользователя.
8. Мультидокументное сравнение для глубокого анализа
Что даёт RAG:
- Позволяет сравнивать несколько документов: отчёты о прибыли, новости, форумы трейдеров.
- Генерация сводного отчёта для быстрого принятия решения.
Пример:
- «Сравни последние отчёты Tesla и Apple и скажи, есть ли у Tesla потенциал роста, как у Apple год назад?»
- Bot собирает релевантную статистику, сравнивает данные и формирует заключение.
9. Управление сигналами и алертами с учётом контекстной информации
Что даёт RAG:
- Генерирует сигналы и алерты, учитывая не только «сырые» метрики (цены, объёмы), но и контекст (новости, макроэкономика).
- Снижает риск ложных сигналов.
Пример:
- При приближении ключевых экономических событий (ставка ФРС, инфляция) система предупреждает заранее, опираясь на данные из векторного хранилища (новости, аналитика) и рекомендации модели.
10. Создание интерактивных “разговорных” сценариев
Что даёт RAG:
- Ретривер обеспечивает контекстные блоки данных из разных документов, а генератор “сшивает” их в виде многоходового диалога.
- Пользователи могут общаться с ботом, как с аналитическим консультантом, погружённым в их историю сделок и материалы компании.
Пример:
- Пользователь ведёт дискуссию о возможном слиянии компаний, указывает на несколько статей и хочет понять, как это повлияет на его портфель.
- Bot поэтапно анализирует документы, распознаёт конфликтующие факты, предлагает обоснованные точки зрения.
Коротко о главном
Применение RAG даёт возможность Mercury Bot не просто “отвечать” на вопросы, а комбинировать внутренние данные (портфель пользователя, исторические сделки, документацию по продукту) с внешними материалами (новостными статьями, PDF-отчётами, аналитическими обзорами). Это делает ответы более точными, контекстуальными и полезными для трейдера любого уровня.
Ключевые выгоды:
- Объединение внутренних и внешних данных
- Улучшенное понимание пользовательского контекста
- Сокращение времени на поиск релевантной информации
- Персонализированные рекомендации и стратегии
- Более глубокая аналитика и обучающий эффект
Таким образом, рассмотренный в курсе подход RAG может значительно усилить функционал Mercury Bot, делая взаимодействие с системой гораздо полезнее и эффективнее для конечного пользователя.
Below is a complete end-to-end use case showing how an automated trading solution can leverage RAG to combine internal data (user’s trades, preferences, portfolio) with external data (market news, financial reports, and so forth). This walkthrough highlights key technical components (indexing, retrieval, generation) and demonstrates how they fit into one continuous loop for decision-making and execution.
1. High-Level Scenario
-
Data Collection
- Pull user-specific trading data (portfolio, transaction history, risk profile).
- Scrape external sources (financial PDFs, news feeds, analytics).
- Store everything in a vector database (e.g., Chroma DB).
-
Retrieval
- Convert new queries or triggers into vector embeddings.
- Retrieve relevant documents/fragments from the vector database.
-
Generation (RAG)
- Feed retrieved documents + user query to a Large Language Model (LLM).
- Model generates an automated trading strategy or immediate trading action suggestion.
-
Trading Execution
- Automatically place or simulate trades via a broker API (depending on user preference).
- Record outcome and update logs.
-
Feedback Loop
- New trades and results get stored back into the system.
- Continuous improvement as more data is ingested.
2. System Components
Below is the architecture you might adopt:
3. Step-by-Step Implementation
3.1 Environment Setup
- Python 3.9+
- Libraries:
openai,chroma-db,sentence-transformers(or any embedding library),requests(for data fetching), and a broker API library (e.g.,alpaca-trade-api,ccxtfor crypto, etc.).
pip install openai chromadb sentence-transformers alpaca-trade-api
3.2 Data Ingestion & Preprocessing
We want to pull two categories of data:
- Internal data: user trades, portfolio details, risk preferences.
- External data: news articles, PDF reports, market commentary.
Below is an example snippet showing how to load and chunk these documents:
import os
import glob
from sentence_transformers import SentenceTransformer
# A simple function to split text into overlapping chunks
def chunk_text(text, chunk_size=1000, overlap=100):
chunks = []
start = 0
while start < len(text):
end = start + chunk_size
chunks.append(text[start:end])
start += chunk_size - overlap
return chunks
def load_external_docs(directory_path):
all_texts = []
for file_path in glob.glob(os.path.join(directory_path, "*.txt")):
with open(file_path, "r", encoding="utf-8") as f:
text = f.read()
# break text into chunks
doc_chunks = chunk_text(text, chunk_size=1000, overlap=100)
all_texts.extend(doc_chunks)
return all_texts
# Example usage: load external news or PDF-to-text outputs
external_docs = load_external_docs("market_reports")
# Example user data:
user_portfolio_text = """
Portfolio:
- AAPL: 50 shares
- TSLA: 10 shares
- BTC: 0.5
Transaction History:
- Bought TSLA at $200
- Sold 10 AAPL at $160
Risk Appetite: moderate
...
"""
user_chunks = chunk_text(user_portfolio_text, chunk_size=500, overlap=50)
all_texts = external_docs + user_chunks
3.3 Indexing into Vector Store (Chroma DB)
Now we embed these chunks and store them in a Chroma collection. We’ll use a SentenceTransformer for embeddings, but you could also use OpenAIEmbeddings if you have an OpenAI API key.
import chromadb
from chromadb.config import Settings
# 1. Initialize embedding model
embedding_model = SentenceTransformer('all-MiniLM-L6-v2')
def embed_texts(texts):
return embedding_model.encode(texts, convert_to_numpy=True)
# 2. Initialize Chroma client & collection
chroma_client = chromadb.Client(Settings(chroma_db_impl="duckdb+parquet", persist_directory="chroma_db"))
collection = chroma_client.create_collection(name="trading_docs")
# 3. Insert documents into collection
# The "documents" here are text fragments, "metadatas" can store extra info.
for i, chunk in enumerate(all_texts):
embedding_vector = embed_texts([chunk])[0] # single-chunk embedding
collection.add(
documents=[chunk],
metadatas=[{"source": "user_data" if i >= len(external_docs) else "market_report"}],
ids=[f"doc_{i}"],
embeddings=[embedding_vector]
)
Tip: If you have many documents, you’ll likely want to batch-embed for efficiency.
3.4 Retriever + RAG Pipeline
When a user or system event triggers the “Need a trading action” step, we:
- Create an embedding for the query/context.
- Perform a similarity search in the Chroma collection.
- Pass the relevant documents into the prompt for the LLM.
import openai
openai.api_key = os.getenv("OPENAI_API_KEY")
def retrieve_relevant_docs(query, top_k=5):
query_vec = embed_texts([query])[0]
results = collection.query(
query_embeddings=[query_vec],
n_results=top_k
)
retrieved_docs = results["documents"][0] # list of doc texts
return retrieved_docs
def generate_rag_response(user_query):
# 1. Retrieve relevant chunks
docs = retrieve_relevant_docs(user_query, top_k=3)
# 2. Construct prompt
context_snippets = "\n\n".join(docs)
prompt = f"""
You are Mercury, an AI trading assistant.
Here are some context snippets from your knowledge base:
{context_snippets}
Based on the above context, answer the following user query:
User query: "{user_query}"
Provide a concise yet thorough trading recommendation or next step.
If the question cannot be answered from context, say so.
"""
# 3. Call OpenAI's GPT model
response = openai.Completion.create(
model="text-davinci-003",
prompt=prompt,
temperature=0.7,
max_tokens=300
)
answer = response["choices"][0]["text"].strip()
return answer
# Example usage:
user_query = "Should I increase my position in AAPL based on recent market conditions?"
rag_answer = generate_rag_response(user_query)
print("RAG Recommendation:", rag_answer)
3.5 Executing Trades via Broker API
After generating a recommendation, the system can automatically place trades using a broker API. Below is an example using Alpaca (paper trading mode for safety):
import alpaca_trade_api as tradeapi
API_KEY = "YOUR_ALPACA_API_KEY"
API_SECRET = "YOUR_ALPACA_SECRET_KEY"
BASE_URL = "https://paper-api.alpaca.markets" # paper trading endpoint
alpaca_api = tradeapi.REST(API_KEY, API_SECRET, BASE_URL, api_version='v2')
def execute_trade(signal):
"""
Example `signal` might be a dictionary:
{
'symbol': 'AAPL',
'action': 'BUY',
'qty': 10
}
"""
symbol = signal['symbol']
action = signal['action']
qty = signal['qty']
if action.upper() == 'BUY':
alpaca_api.submit_order(
symbol=symbol,
qty=qty,
side='buy',
type='market',
time_in_force='gtc'
)
elif action.upper() == 'SELL':
alpaca_api.submit_order(
symbol=symbol,
qty=qty,
side='sell',
type='market',
time_in_force='gtc'
)
print(f"Trade executed: {action} {qty} of {symbol}")
You can combine the final recommendation from the LLM with logic that extracts the desired trade action/amount (e.g., via an additional prompt or a small parser).
3.6 Feedback Loop & Logging
Each trade, outcome, or updated portfolio state should be re-indexed into the vector database to refine future answers. For instance, after a trade:
def log_and_reindex_trade_result(symbol, qty, side, outcome_text):
log_text = f"Executed {side} of {qty} {symbol}.\nOutcome: {outcome_text}\n"
# Optionally chunk the text or store it as a single chunk:
embedding_vector = embed_texts([log_text])[0]
doc_id = f"trade_log_{symbol}_{qty}_{side}"
collection.add(
documents=[log_text],
metadatas=[{"source": "trade_log"}],
ids=[doc_id],
embeddings=[embedding_vector]
)
Over time, you’ll accumulate trading logs and performance data. The LLM can then reference these historical outcomes to refine or contextualize future recommendations.
4. Bringing It All Together in One Loop
Below is a pseudo-code outline that ties the steps into a single automated “loop” that could run on a schedule or triggered by certain market events:
def automated_trading_loop():
# 1. Fetch latest market or user queries
user_query = "System trigger: Check if we should adjust AAPL holdings"
# 2. RAG to generate a strategy
recommendation = generate_rag_response(user_query)
print("Strategy Suggestion:", recommendation)
# 3. Parse the recommendation into a trade signal (BUY/SELL, symbol, qty)
# For real use, you'd implement NLP or a rules-based parser.
example_signal = {
"symbol": "AAPL",
"action": "BUY",
"qty": 5
}
# 4. Execute the trade
execute_trade(example_signal)
# 5. Log the trade result/outcome
trade_outcome = "Filled at $170.25. Expecting short-term upswing."
log_and_reindex_trade_result(
symbol=example_signal["symbol"],
qty=example_signal["qty"],
side=example_signal["action"],
outcome_text=trade_outcome
)
# 6. Loop or schedule next iteration
# e.g., sleep(3600) for an hourly schedule,
# or run triggered by Webhook events.
In a production system, you’d have a more robust pipeline:
- Scheduled tasks or real-time triggers for new data ingestion.
- Fine-tuned prompts to ensure safe, contextually rich generation.
- Validation steps to confirm that trades meet your risk management criteria.
5. Key Benefits & Takeaways
-
Personalized Context RAG ensures the trading bot pulls from relevant user data + up-to-date external market info.
-
Scalable Knowledge Base As you ingest more PDF reports, news articles, or user logs, the vector database grows—improving future retrieval.
-
Reduced Hallucination By combining a retriever (search) with generation, the model stays anchored to real data, increasing response reliability.
-
Feedback Loop Every trade’s outcome gets fed back in, forming an ever-improving knowledge cycle.
-
Automated Action The final step is bridging the LLM suggestions to a broker API, enabling a fully automated or semi-automated trading workflow.
Conclusion
Using RAG in an automated trading solution allows for:
- Real-time ingestion of user-specific and external data.
- Context-driven answers and strategies rather than generic AI guesses.
- Continuous improvement via a feedback loop that logs outcomes and retrains on new data.
The example code above is a starting point: adapt it to your environment, broker APIs, and chosen LLM settings. With robust logging and risk management, this loop provides a powerful end-to-end solution for AI-enhanced automated trading.
Below is a complete end-to-end use case illustrating how an automated trading solution might leverage advanced RAG (Retriever-Augmented Generation) techniques — such as multi-query approaches, RAG Fusion, and hierarchical indexing — to combine both internal trading data (user portfolio, transaction history, risk profile) and external sources (market news, technical reports, PDFs) in one feedback loop. We’ll show how to integrate these steps into a continuous workflow, referencing the new course topics like multi-query generation, question decomposition, indexing with multiple representations, and advanced retrieval strategies.
1. High-Level Flow
-
Data Ingestion & Multi-Representation Indexing
- Load user’s private data (portfolio, history).
- Pull external data (market news, PDFs, fundamental analysis).
- Store multiple representations (summaries, token-level embeddings, hierarchical clusters) in a vector DB (e.g., Chroma).
-
Multi-Query & Retrieval
- Decompose complex trading queries into multiple sub-queries.
- Retrieve relevant documents from the vector DB using advanced search (RAG Fusion, hierarchical indexing, multi-query merges).
-
RAG Generation
- Combine user context + retrieved docs in the LLM’s prompt.
- Use “step back” prompts or “hypothetical docs” if needed, to refine search.
-
Trading Signal/Action
- Parse the LLM output for a recommended strategy or direct trade instructions.
-
Execution & Feedback
- Place trades (via a broker API).
- Log outcomes (performance, success/failure).
- Re-ingest these logs into the vector DB for improved context on future queries.
2. Architecture Overview
Here’s a more granular depiction, including advanced concepts from the course (multi-query, question decomposition, RAG Fusion, “step-back” prompts, and so on):
Key differences from a basic RAG:
- Multi-Representation: We store both raw text chunks (token-level embedding) and summarized versions (short/long summaries) for flexible retrieval.
- Multi-Query: We generate multiple sub-queries (with “step back” or “query rewriting”) to ensure broader coverage.
- RAG Fusion: We unify multiple retrieved sets to produce a final, more reliable set of documents.
3. Step-by-Step Implementation
3.1 Environment & Dependencies
- Python 3.9+
- Libraries:
openai,chroma-db,langchain(for advanced chain logic),sentence-transformersor another embedding library,- A broker API (e.g.,
alpaca-trade-api,ccxtfor crypto, etc.).
- (Optional) LangSmith or Langraph for tracing, debugging, or building complex flows.
pip install openai chromadb langchain sentence-transformers alpaca-trade-api
3.2 Ingestion & Multi-Representation Indexing
A. Document Loading & Splitting
We gather:
- User Data: Transaction history, open positions, risk preferences.
- External Data: PDFs, market news, research documents (converted to text).
Below is simplified code to chunk text into smaller pieces for indexing; we also demonstrate creating summaries for each chunk (like the “index with multiple representations” concept).
import os
import glob
from sentence_transformers import SentenceTransformer
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.chains.summarize import load_summarize_chain
from langchain.llms import OpenAI
embedding_model = SentenceTransformer("all-MiniLM-L6-v2")
llm_for_summaries = OpenAI(temperature=0.3)
def chunk_texts(text, chunk_size=1000, overlap=100):
splitter = RecursiveCharacterTextSplitter(
chunk_size=chunk_size,
chunk_overlap=overlap
)
return splitter.split_text(text)
def generate_summary(chunk):
"""Use an LLM to summarize the chunk (short representation)."""
chain = load_summarize_chain(llm_for_summaries, chain_type="map_reduce")
# The chain expects docs in a format, so we wrap chunk in a "Document" object:
from langchain.docstore.document import Document
doc_obj = Document(page_content=chunk)
summary_result = chain.run([doc_obj])
return summary_result.strip()
# For demonstration, assume user_portfolio and external docs were loaded as raw text:
user_portfolio_text = """
User Portfolio:
- AAPL: 50 shares
- TSLA: 10 shares
Risk: moderate
Transaction history: ...
"""
# Chunk user data
user_data_chunks = chunk_texts(user_portfolio_text, chunk_size=500, overlap=50)
# Suppose we also loaded news from `market_reports/` directory
external_chunks = []
for path in glob.glob("market_reports/*.txt"):
with open(path, "r", encoding="utf-8") as f:
text = f.read()
external_chunks.extend(chunk_texts(text))
all_chunks = user_data_chunks + external_chunks
B. Creating Multiple Representations
We store both:
- Raw chunk embedding (token-level).
- Summary embedding (short representation).
import chromadb
from chromadb.config import Settings
# 1. Initialize Chroma
chroma_client = chromadb.Client(Settings(
chroma_db_impl="duckdb+parquet",
persist_directory="chroma_db"
))
collection = chroma_client.create_collection(name="trading_docs")
def embed(text):
return embedding_model.encode([text])[0] # single vector
# 2. Index each chunk
for i, chunk in enumerate(all_chunks):
raw_embed = embed(chunk)
summary = generate_summary(chunk)
summary_embed = embed(summary)
# You might store them in two separate collections or a single one with metadata
collection.add(
documents=[chunk],
metadatas=[{
"type": "raw",
"summary": summary
}],
ids=[f"doc_{i}_raw"],
embeddings=[raw_embed]
)
# Optionally add a second doc with “summary”:
collection.add(
documents=[summary],
metadatas=[{
"type": "summary",
"full_chunk_id": f"doc_{i}_raw"
}],
ids=[f"doc_{i}_summary"],
embeddings=[summary_embed]
)
By storing two representations, we can retrieve either raw or summarized text based on query complexity.
3.3 Multi-Query Retrieval
A. Generating Multiple Queries (“Step Back” or “Multi-Query”)
When the user or system triggers a complex question (e.g., “Should I adjust my AAPL position based on the latest Fed announcements and my risk profile?”), we can use the Multi-Query approach from the course:
- Ask the LLM to create 2-3 variant queries (including a “step-back” or “high-level” question).
- Retrieve from the vector store using each query.
- Merge the results (RAG Fusion).
from langchain.chains import LLMChain
from langchain.prompts import PromptTemplate
# Prompt to generate sub-queries
multi_query_prompt = PromptTemplate(
input_variables=["user_question"],
template="""
You are an expert in finance and trading. The user has asked: "{user_question}".
Please create 2-3 rephrased or related sub-queries that might surface relevant documents
from a vector database. Include a broader "step back" query if needed.
"""
)
llm = OpenAI(temperature=0.5)
def generate_sub_queries(user_question):
chain = LLMChain(llm=llm, prompt=multi_query_prompt)
output = chain.run(user_question)
# Suppose output is a short list. We’ll just do a naive split by newline:
sub_queries = [q.strip("- ") for q in output.split("\n") if q.strip()]
return sub_queries
B. Retrieval + Merging
We query the vector DB for each sub-query, gather top k results, and unify them (sometimes called RAG Fusion).
def retrieve_docs(sub_query, top_k=3):
vec = embedding_model.encode([sub_query])[0]
results = collection.query(query_embeddings=[vec], n_results=top_k)
# Flatten document texts
docs = results["documents"][0]
return docs
def multi_query_retrieve(user_question):
# 1. Generate sub-queries
sub_queries = generate_sub_queries(user_question)
# 2. Retrieve docs for each sub-query
all_docs = []
for sq in sub_queries:
retrieved = retrieve_docs(sq)
all_docs.extend(retrieved)
# 3. (Optional) Deduplicate or rank results
unique_docs = list(set(all_docs)) # naive dedup
return unique_docs
Now we have a set of raw or summary documents from each sub-query.
3.4 RAG Generation
We feed the retrieved docs + user’s original question into the LLM prompt. We can also apply a “hypothetical document” approach or a “step back” prompt if needed.
def rag_generate_answer(user_question):
# 1. Get docs from multi-query retrieval
relevant_docs = multi_query_retrieve(user_question)
# 2. Construct the final prompt
context_snippets = "\n\n".join(relevant_docs)
final_prompt = f"""
You are Mercury, an AI finance assistant.
Here is context from your knowledge base:
{context_snippets}
Now answer the user's question:
"{user_question}"
Provide a concise, yet thorough trading recommendation.
If you cannot answer from the context, say so.
"""
response = openai.Completion.create(
model="text-davinci-003",
prompt=final_prompt,
max_tokens=300,
temperature=0.7
)
answer = response["choices"][0]["text"].strip()
return answer
3.5 Parse Trading Actions & Execution
Once we have a recommendation, we might parse it to see if it suggests buying/selling. This could be an agent or a small rules-based parser:
def parse_trade_recommendation(rag_answer):
"""
Minimal example: look for keywords like "BUY" or "SELL" with a ticker and quantity.
In production, consider using an LLM chain specifically for extracting structured data.
"""
lines = rag_answer.split("\n")
for line in lines:
if "BUY" in line.upper() or "SELL" in line.upper():
# Example: "Buy 10 shares of AAPL"
# We do naive parsing:
tokens = line.split()
action = "BUY" if "BUY" in line.upper() else "SELL"
symbol = "AAPL" if "AAPL" in line.upper() else "TSLA" if "TSLA" in line.upper() else None
# etc... real system would be more robust
qty = 10 # default guess
return {"action": action, "symbol": symbol, "qty": qty}
return None
Then execute via your broker:
import alpaca_trade_api as tradeapi
API_KEY = "YOUR_ALPACA_API_KEY"
API_SECRET = "YOUR_ALPACA_SECRET_KEY"
BASE_URL = "https://paper-api.alpaca.markets"
alpaca_api = tradeapi.REST(API_KEY, API_SECRET, BASE_URL, api_version='v2')
def execute_trade(signal):
if not signal:
print("No actionable signal found.")
return
side = signal["action"].lower()
alpaca_api.submit_order(
symbol=signal["symbol"],
qty=signal["qty"],
side=side,
type='market',
time_in_force='gtc'
)
print(f"Executed {side} {signal['qty']} of {signal['symbol']}")
3.6 Feedback Loop & Re-Ingestion
After the trade is placed, capture details (fill price, PnL updates, etc.) and store them back in the vector DB. Over time, you build a knowledge base of trade outcomes that can be retrieved for future decisions.
def log_trade_result(symbol, qty, side, outcome_text):
log_text = f"Trade log:\nSymbol: {symbol}\nAction: {side}\nQty: {qty}\nOutcome: {outcome_text}"
log_embedding = embedding_model.encode([log_text])[0]
doc_id = f"log_{symbol}_{side}_{qty}"
collection.add(
documents=[log_text],
metadatas=[{"type": "trade_log"}],
ids=[doc_id],
embeddings=[log_embedding]
)
4. Bringing It All Together
Below is a pseudo-code “one-loop” function that demonstrates the entire advanced RAG cycle:
def automated_trading_loop():
# 1. System or user query
user_question = "Should I adjust my AAPL position after the Fed's announcement?"
# 2. RAG Generation
rag_answer = rag_generate_answer(user_question)
print("RAG Answer:", rag_answer)
# 3. Parse trade recommendation
trade_signal = parse_trade_recommendation(rag_answer)
# 4. Execute trade if recommended
if trade_signal:
execute_trade(trade_signal)
# Example outcome
outcome_text = "Filled at $172.50. Short-term bullish sentiment."
log_trade_result(
symbol=trade_signal["symbol"],
qty=trade_signal["qty"],
side=trade_signal["action"],
outcome_text=outcome_text
)
# 5. (Optional) schedule next iteration or run on triggers
In production, you may:
- Use hierarchical indexing (e.g., Raptor) for large doc sets.
- Incorporate “step-back” or “hypothetical doc” expansions to further refine retrieval.
- Employ LangSmith or Langraph for debugging/tracing each sub-step in multi-query retrieval.
- Conduct modular testing on each chain step (e.g., to reduce hallucinations or irrelevant docs).
- Manage user data permissions (private vs. public docs) with advanced filtering.
5. Key Insights from the New Course
-
Multi-Query Generation
- Splitting user queries into multiple formulations can improve recall (avoid missing key docs).
-
RAG Fusion
- Merging results from multiple sub-queries or partial retrieval steps (especially relevant if your data is distributed among multiple indexes or you want to cross-check doc sets).
-
Hierarchical Indexing (Raptor)
- For large corpora, building a tree of summaries helps retrieving high-level or detailed fragments, depending on the query context.
-
“Step Back” Prompt
- Encouraging the LLM to think more abstractly can surface broader or earlier references that a direct question might miss.
-
Multiple Representations
- Storing raw doc embeddings + summaries allows flexible retrieval. Summaries can quickly bring broad context; raw chunks provide detail.
-
Adaptive RAG
- Incorporating logic flows (like a conditional “if docs are insufficient, do X or do an external web search”) to handle uncertain queries.
Conclusion
By combining advanced multi-query retrieval, hierarchical indexing, and “step back” prompts, this RAG-based automated trading system delivers context-rich trading recommendations leveraging both private user data and public market intelligence. The system re-ingests each trade outcome for continuous improvement and adapts to complex queries by fusing multiple retrieval results. This approach encapsulates the cutting-edge RAG strategies outlined in the new course, providing a scalable and powerful architecture for automated trading or any other domain requiring in-depth, context-aware solutions.
