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.
Backtest runner
@qtrader
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.
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.
Consumption guardrails
@agentcosts
Set and check consumption guardrails for an AI product: per-customer daily and monthly spend caps, month-end forecasts, spend spike rules, runaway agent runs, and failure rate spikes, plus a runbook for what to do when each alert fires. Runs on usage files; exit code 2 on critical alerts for cron or CI.
