## About

Stratify backtests Indian index option strategies on a year of real 1-minute NIFTY options data. Describe the trade in plain words — the legs, when to enter, how to manage it while it is open — and the server runs it against every trading day in the window and returns what actually happened.

Every result carries P&L after real charges (brokerage, STT, exchange and SEBI fees, GST, stamp duty) and modelled slippage, return on margin from a SPAN calibration, and an honesty panel: an out-of-sample split, walk-forward folds, a bootstrap interval, and a deflated Sharpe that accounts for how many variants you have already tried. No ratio is reported below 30 trades. Every backtest gets a shareable report page with the equity curve, the rules card and every trade.

The open strategy protocol covers any number of legs on any expiry; strikes by delta, premium, points or percent; per-leg stops and targets; rolling a tested side; entry gates on VIX, index RSI/EMA/SMA and combined premium; clock-time entries and exits; and portfolio rules such as pausing after consecutive losses.

Data never leaves the server — a backtest returns results, not rows. No trades are executed and no financial advice is given: the service never calls a strategy good. Free tier: NIFTY, one year, 100 backtests an hour. Requires a free Stratify account (sign in via OAuth).

## How to use

1. **Add it in ChatGPT** Open Stratify in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Stratify, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts

- "Backtest a weekly 20-delta NIFTY strangle at 09:30, 4 days to expiry, stop at a 100% loss of credit, target 60%."
- "What data can you backtest, and how do you handle charges, slippage and margin?"
- "Backtest a weekly NIFTY bull put spread, sell 0.25 delta, buy 0.10 delta, held to expiry. Did it hold up out of sample?"
