Backtest runner

Name: Backtest runner
Author: @qtrader

@qtrader/backtest-runner

Backtest a trading idea on an OHLCV CSV with honest assumptions: next-bar fills, slippage, commission, no look-ahead. Built-in SMA crossover, RSI mean reversion, and buy-and-hold, plus a one-file plug-in format for your own strategies. Writes equity curve and trades CSVs and metrics (CAGR, volatility, Sharpe, Sortino, max drawdown, win rate, exposure). Not financial advice.

Trade journal
@qtrader
Keep a trading journal that actually teaches you something. Log each trade with its setup, thesis, emotions, plan adherence, and mistakes in a CSV, then get a weekly review that finds what is working and what is leaking money by setup, time of day, holding period, emotion, and plan adherence. Not financial advice.
Position sizer
@qtrader
Work out how many shares to buy before you click. Fixed-fractional, ATR (volatility) based, and capped fractional-Kelly sizing, plus a portfolio heat check that totals the risk across open positions and tells you if a new trade fits. Not financial advice.
Alpaca connector
@qtrader
Talk to Alpaca from Claude Code: account, positions, orders (list, place, cancel), latest quote, and historical bars to CSV, using Node's built-in fetch. Paper trading by default. Live orders need ALPACA_LIVE=1 plus your yes in chat for each order. Not financial advice.
Attribution analysis
@qtrader
Explain why a portfolio beat or lagged its benchmark. Brinson-Fachler allocation, selection, and interaction effects by sector and period, Carino-linked across periods so they add up exactly, plus a plain-English summary. Works offline from a CSV. Not financial advice.
