Use when working with trading strategies, backtesting, stock data, FinLabDataFrame, factor analysis, stock selection, or when the user mentions FinLab, trading, quant trading, US equity, S&P 500 / NASDAQ 100, SPY / QQQ, sector or leveraged ETFs, ETF rotation, 美股, or stock market analysis. Includes data access, strategy development, backtesting workflows, best practices, and US-market specifics (data availability map, filing-date-aligned quarterly fundamentals, US universe construction, USMarket vs. USFundMarket defaults, and ETF backtesting). compatibility Requires Python 3.10+ and uv package manager (https://docs.astral.sh/uv/) FinLab Quantitative Trading Package Prerequisites Before running any FinLab code, verify these in order: uv is installed (Python package manager): uv --version If uv is not installed, tell the user to install it. After installing, ensure uv is on PATH: source $HOME /.local/bin/env 2>/dev/null # Add uv to current shell FinLab is installed via uv (requires >= 2.0.0): uv python install 3.12 # Ensure Python is available (skip if already installed) uv pip install --system \"finlab>=2.0.0\" 2>/dev/null || uv pip install \"finlab>=2.0.0\" Or use uv run for zero-setup execution (recommended for one-off scripts): uv run --with \"finlab\" python3 script.py uv run --with auto-creates a temporary environment with dependencies — no venv management needed. Prefer zero-install? Run notebooks directly in FinLab Studio — a hosted Jupyter environment with finlab preinstalled and your API token already wired up. API Token is set (required - finlab will fail without it): If no token, use finlab's built-in login (available in >= 1.5.9, improved Firebase flow in v1.5.11): import finlab finlab.login() # Opens browser for Google OAuth, saves token automatically This handles the full OAuth flow (browser login, token retrieval, .env storage) automatically. Tokens are bound to a FinLab account at finlab.finance — finlab.login() provisions one on first use. Language Respond in the user's language. If user writes in Chinese, respond in Chinese. If in English, respond in English. Market Support FinLab supports TW (default), US, KR, JP, HK, plus Taiwan emerging ( rotc ) and Taiwan convertible bonds ( tw_cb ). Pick the market once per session with data.set_market(<code>) ; generic dataset names like price:收盤價 or monthly_revenue:當月營收 resolve to the active market's tables, so strategy code is written the same way across markets. data.set_market('rotc') (v2.0.9) enables 興櫃 (TW emerging) — use it when you need pre-listing price action or revenue factors that don't exist in the main TSE/OTC catalog. The rest of this file plus dataframe-reference.md , backtesting-reference.md , best-practices.md , factor-analysis-reference.md , and machine-learning-reference.md are market-agnostic — the APIs behave the same across markets. For US-market work — whether single-name equities ( data.set_market('us') ) or ETFs/funds ( data.set_market('us_fund') ) — read us-market.md first . Queries that should trigger it include: US equity, S&P 500, NASDAQ 100, 美股, SPY / QQQ, sector SPDRs, leveraged / inverse ETFs, ETF rotation, us_price:* , us_fund_price:* , data.us_universe(...) , or us_income_statement:* / us_cash_flow:* / us_balance_sheet:* . It documents: Which US data tables are safe for backtesting versus current-snapshot-only (analyst consensus, ratios, DCF are live-only — do not use them historically) Filing-date-aligned quarterly fundamentals ( key_date == filing_date ) — no .shift() workaround needed Report API names on US ( creturn / daily_creturn / get_stats() ; no get_equity() ) US backtest defaults for both markets: USMarket ( fee_ratio=0 , tax_ratio=0 , trade_at_price='close' ) and USFundMarket for ETF/fund backtests How data.set_market(...) is the session-scope switch (there is no market= kwarg on data.get() ) Dollar-volume-top-N universe construction (works back to 2016), S&P 500 / NASDAQ 100 membership via data.us_universe(index='S&P 500' | 'NASDAQ 100') with its 2022-11 history-start caveat, quality gates, and sector-exclusion rationale Lookahead-bias checklist specific to US data (rolling-window universe filters, survivorship avoidance) ETF / sector-rotation backtesting via USFundMarket and us_fund_price:* Other-market queries can skip that file. API Token Tiers & Usage Token Tiers Tier Daily Limit Token Pattern Free 500 MB ends with #free VIP 5000 MB no suffix Usage Reset Resets daily at 8:00 AM UTC+8 When limit exceeded, user must wait for reset or upgrade to VIP at finlab.finance Quick Start Example from finlab import data from finlab.backtest import sim # 1. Fetch data close = data.get( \"price:收盤價\" ) vol = data.get( \"price:成交股數\" ) pb = data.get( \"price_earning_ratio:股價淨值比\" ) # 2. Create conditions cond1 = close.rise( 10 ) # Rising last 10 days cond2 = vol.average( 20 ) > 1000 * 1000 # High liquidity cond3 = pb.rank(axis= 1 , pct= True ) < 0.3 # Low P/B ratio # 3. Combine conditions and select stocks position = cond1 & cond2 & cond3 position = pb[position].is_smallest( 10 ) # Top 10 lowest P/B # 4. Backtest report = sim(position, resample= \"M\" , upload= False ) # 5. Print metrics - Two equivalent ways: # Option A: Using metrics object print (report.metrics.annual_return()) print (report.metrics.sharpe_ratio()) print (report.metrics.max_drawdown()) # Option B: Using get_stats() dictionary (different key names!) stats = report.get_stats() print ( f\"CAGR: {stats[ 'cagr' ]: .2 %} \" ) print ( f\"Sharpe: {stats[ 'monthly_sharpe' ]: .2 f} \" ) print ( f\"MDD: {stats[ 'max_drawdown' ]: .2 %} \" ) # Benchmark stats (finlab >= 2.0.17): same keys via report.get_benchmark_stats() # 6. Write the FinLab-generated HTML report (REQUIRED — do not hand-roll your own HTML) report.to_html( \"report.html\" ) print ( \"Open report.html to inspect equity curve, monthly returns, drawdown, and trade list.\" ) Core Workflow: 5-Step Strategy Development Step 1: Fetch Data Use data.get(\"<TABLE>:<COLUMN>\") to retrieve data: from finlab import data # Price data close = data.get( \"price:收盤價\" ) volume = data.get( \"price:成交股數\" ) # Financial statements roe = data.get( \"fundamental_features:ROE稅後\" ) revenue = data.get( \"monthly_revenue:當月營收\" ) # Valuation pe = data.get( \"price_earning_ratio:本益比\" ) pb = data.get( \"price_earning_ratio:股價淨值比\" ) # Institutional trading foreign_buy = data.get( \"institutional_investors_trading_summary:外陸資買賣超股數(不含外資自營商)\" ) # Technical indicators rsi = data.indicator( \"RSI\" , timeperiod= 14 ) macd, macd_signal, macd_hist = data.indicator( \"MACD\" , fastperiod= 12 , slowperiod= 26 , signalperiod= 9 ) Filter by market/category using data.universe() : # Limit to specific industry with data.universe(market= 'TSE_OTC' , category=[ '水泥工業' ]): price = data.get( 'price:收盤價' ) # Set globally data.set_universe(market= 'TSE_OTC' , category= '半導體' ) Use data.search('keyword', market='<market>') to discover available datasets. Supported markets: tw , us , kr , jp , hk . Use keywords in the dataset's native language (e.g. data.search('營收', market='tw') , data.search('revenue', market='us') ). Step 2: Create Factors & Conditions Use FinLabDataFrame methods to create boolean conditions: # Trend rising = close.rise( 10 ) # Rising vs 10 days ago sustained_rise = rising.sustain( 3 ) # Rising for 3 consecutive days # Moving averages sma60 = close.average( 60 ) above_sma = close > sma60 # Ranking top_market_value = data.get( 'etl:market_value' ).is_largest( 50 ) low_pe = pe.rank(axis= 1 , pct= True ) < 0.2 # Bottom 20% by P/E # Industry ranking industry_top = roe.industry_rank() > 0.8 # Top 20% within industry See dataframe-reference.md for all FinLabDataFrame methods. Step 3: Construct Position DataFrame Combine conditions with & (AND), | (OR), ~ (NOT): # Simple position: hold stocks meeting all conditions position = cond1 & cond2 & cond3 # Limit number of stocks position = factor[condition].is_smallest( 10 ) # Hold top 10 # Entry/exit signals with hold_until entries = close > close.average( 20 ) exits = close < close.average( 60 ) position = entries.hold_until(exits, nstocks_limit= 10 , rank=-pb) Important: Position DataFrame should have: Index : DatetimeIndex (dates) Columns : Stock IDs (e.g., '2330', '1101') Values : Boolean (True = hold) or numeric (position size) Step 4: Backtest from finlab.backtest import sim # Basic backtest report = sim(position, resample= \"M\" ) # With risk management report = sim( position, resample= \"M\" , stop_loss= 0.08 , take_profit= 0.15 , trail_stop= 0.05 , position_limit= 1 / 3 , fee_ratio= 1.425 / 1000 / 3 , tax_ratio= 3 / 1000 , trade_at_price= 'open' , upload= False ) # Extract metrics - Two ways: # Option A: Using metrics object print ( f\"Annual Return: {report.metrics.annual_return(): .2 %} \" ) print ( f\"Sharpe Ratio: {report.metrics.sharpe_ratio(): .2 f} \" ) print ( f\"Max Drawdown: {report.metrics.max_drawdown(): .2 %} \" ) # Option B: Using get_stats() dictionary (note: different key names!) stats = report.get_stats() print ( f\"CAGR: {stats[ 'cagr' ]: .2 %} \" ) # 'cagr' not 'annual_return' print ( f\"Sharpe: {stats[ 'monthly_sharpe' ]: .2 f} \" ) # 'monthly_sharpe' not 'sharpe_ratio' print ( f\"MDD: {stats[ 'max_drawdown' ]: .2 %} \" ) # same name # Benchmark comparison (finlab >= 2.0.17): same ffn keys, computed on the # market benchmark over the backtest period — no need to recompute from # market.get_benchmark() bench = report.get_benchmark_stats() print ( f\"Benchmark CAGR: {bench[ 'cagr' ]: .2 %} | MDD: {bench[ 'max_drawdown' ]: .2 %} \" ) See backtesting-reference.md for complete sim() API. Step 4.5: Deliver the FinLab HTML Report (REQUIRED) Follow each backtest the user will review with one HTML file — the one FinLab generates: report = sim(position, resample= \"M\" , upload= False ) report.to_html( \"report.html\" ) # the FinLab-generated file is the deliverable The canonical deliverable is the file generated by report.to_html() — do not hand-roll a separate report (custom HTML pages, Plotly summaries, dashboards, markdown files) unless the user explicitly asks. To summarize results, print a short terminal summary and point to the FinLab report. Exception: in batch runs (parameter sweeps, screening many variants), skip per-run HTML and write it only for the final strategy the user will review. Pick a descriptive filename when running more than one strategy in the same session (e.g. momentum_top10.html , value_lowpb.html ) so the user can compare without overwriting. After writing, tell the user the path so they can open it. Use report.to_terminal() only as a supplement for non-GUI terminals; it does not replace the HTML. See the \" report.to_html() — the canonical deliverable\" section of backtesting-reference.md for details on what the file contains. Step 5: Execute Orders (Optional) Convert backtest results to live trading: from finlab.online.order_executor import Position, OrderExecutor from finlab.online.sinopac_account import SinopacAccount # 1. Convert report to position position = Position.from_report(report, fund= 1000000 ) # 2. Connect broker account acc = SinopacAccount() # 3. Create executor and preview orders executor = OrderExecutor(position, account=acc) executor.create_orders(view_only= True ) # Preview first # 4. Execute orders (when ready) executor.create_orders() See trading-reference.md for complete broker setup and OrderExecutor API. Reference Files | File | Content |",
