aipriceaction 0.1.1

Multi-market OHLCV data SDK with AI context builder and LLM integration for Vietnamese stocks, US stocks, crypto, and commodities

aipriceaction

Python SDK for AIPriceAction — OHLCV data access and AI context builder for multi-market investment analysis. Reads from a public S3 archive (no API credentials needed).

Install

pip install aipriceaction

Data Sources

The SDK reads OHLCV data from an S3-compatible archive. All sources are auto-detected from ticker metadata — no need to specify which market a ticker belongs to.

Source	Examples	Intervals
Vietnamese stocks (VCI)	VCB, FPT, VNINDEX	1m, 1h, 1D
US / international stocks (Yahoo)	AAPL, GOOGL, GC=F	1m, 1h, 1D
Cryptocurrency (Binance)	BTCUSDT, ETHUSDT	1m, 1h, 1D
SJC gold	SJC-GOLD	1D

Quick Start

from aipriceaction import AIPriceAction

client = AIPriceAction()

# Ticker metadata
tickers = client.get_tickers()            # all tickers
tickers = client.get_tickers(source="vn") # filter by source

# OHLCV data as DataFrame
df = client.get_ohlcv("VCB", interval="1D")                         # VN stock
df = client.get_ohlcv("AAPL", interval="1D")                        # US stock
df = client.get_ohlcv("BTCUSDT", interval="1D")                     # crypto
df = client.get_ohlcv(tickers=["VCB", "FPT", "BTCUSDT"], interval="1D")  # mixed

# Date range, limit, MA indicators
df = client.get_ohlcv("VCB", start_date="2025-01-01", end_date="2025-04-30", ma=True)
df = client.get_ohlcv("VCB", interval="1D", limit=100, ema=True)    # EMA instead of SMA

Override the S3 endpoint if self-hosting:

client = AIPriceAction(base_url="https://your-s3-endpoint/archive")

Data is cached to disk by default (temp dir). Set cache_dir for persistent caching:

client = AIPriceAction(cache_dir="./cache")

AI Context Builder

Build structured context strings for LLM-powered investment analysis.

from aipriceaction import AIContextBuilder

builder = AIContextBuilder(lang="en")

# Single ticker (VNINDEX included as reference by default)
context = builder.build(ticker="VCB", interval="1D")

# Multi ticker
context = builder.build(tickers=["VCB", "FPT", "TCB"], interval="1D")

# No data — system prompt + disclaimer only
context = builder.build()

# Omit VNINDEX reference
context = builder.build(ticker="VCB", interval="1D", reference_ticker=None)

Browse Question Bank

for q in builder.questions("single"):
    print(f"{q['title']}: {q['snippet']}")

Ask LLM

Requires OPENAI_API_KEY. The context is built once and reused across answer() calls for KV cache efficiency.

builder.build(ticker="VCB", interval="1D")

response = builder.answer("What is the current trend?")
follow_up = builder.answer("What is the support level?")  # faster, KV cache hit

Configuration

Set via environment variables or .env file:

Variable	Default	Description
OPENAI_API_KEY	""	API key for LLM calls
OPENAI_BASE_URL	https://openrouter.ai/api/v1	LLM API endpoint
OPENAI_MODEL	openai/gpt-oss-20b	Default LLM model
AI_CONTEXT_LANG	en	Context language (en or vi)

OpenRouter Models

Curated free-tier models available via OpenRouter:

from aipriceaction.llm_models import OpenRouter

for m in OpenRouter.FREE:
    print(f"{m.id} — {m.label}")

Examples

Build context

from aipriceaction import AIContextBuilder

builder = AIContextBuilder(lang="en")

# Single ticker — prints questions, then full context
builder.build(ticker="VCB", interval="1D")
print(builder._last_context)

Multi-ticker context

builder.build(tickers=["VCB", "FPT", "TCB"], interval="1D")
print(builder._last_context)

System prompt only (no market data)

context = builder.build()
print(context)

Build context + call LLM

Build once, ask multiple questions — the second call is faster due to LLM KV cache.

from aipriceaction import AIContextBuilder

builder = AIContextBuilder(lang="en")

# Build context once
builder.build(ticker="VCB", interval="1D")

# First question (cold)
response1 = builder.answer("What is the current trend?")

# Follow-up (warm — same context prefix, KV cache hit)
response2 = builder.answer("What is the support level?")

Multi-timeframe analysis

Switch timeframe between questions. Pass previous responses as history so the LLM can cross-reference timeframes.

from aipriceaction import AIContextBuilder

builder = AIContextBuilder(lang="en")

# Daily context — big picture
builder.build(ticker="VIC", interval="1D")
daily_response = builder.answer("What is the weekly trend?")

# Hourly context — intraday detail, with daily analysis as history
builder.build(ticker="VIC", interval="1h")
hourly_response = builder.answer(
    "Confirm or reject the daily trend using intraday data.",
    history=[daily_response],
)
