NSE & F&O · Backtest + Journal

Don't just watch.
Let's test the strategy.

Every strategy sounds brilliant in a 12-minute video with cherry-picked charts. Rebuild it here, run it over years of real NIFTY data, and see the equity curve the video didn't show you. Then track whether your live trades actually followed the rules.

Two halves, one system

Prove it, then trade it — and check you actually did

The lab tells you what a strategy is worth. The desk tells you whether you followed it. Most losing traders have a decent strategy and terrible adherence; this is built to show you which one is your problem.

MODULE 01

Strategy Lab

Rebuild any strategy from dropdowns — no coding — and run it over years of real candles.

Rule builder — EMA, SMA, RSI, ATR, MACD, VWAP, Supertrend, Bollinger. Combine with AND/OR.
Honest stats — equity curve, win rate, profit factor, max drawdown, expectancy, average hold.
Every trade listed — entry, exit, reason, R-multiple. No hand-picking.
F&O aware — live NSE lot sizes, expiry handling, per-trade margin.
Save with the source — pin the video link to the result, so you remember who was right.

MODULE 02

Trading Desk

Your live journal — every trade tagged with the strategy it came from.

Log fast — instrument, entry, exit, size, stop, notes, screenshot.
Open positions — running R-multiple and risk on the table right now.
Backtest vs. reality — the number that matters: did the live results match the lab?
Discipline score — how often you followed your own rules vs. improvised.
Syncs everywhere — sign in once, same journal on phone and laptop.

The loop

From "this looks good" to "this actually works"

Spot it

You see a setup in a video, a tweet, or a forum post. Note the entry, exit, and stop rules.

Test it

Rebuild the rules in the Lab and run them over years of NIFTY, Bank Nifty, or any NSE stock.

Trade it

If the numbers hold up, take it live — and log every trade against that saved strategy.

Compare

Live win rate vs. backtest win rate. When they diverge, you know it's you and not the strategy.

Real NSE data, and your API keys never leave your PC

Candles come from your own Fyers account. A small Python fetcher runs locally, pulls the OHLC history you ask for, and writes it into the site as plain data files. Your API secret stays in a local .env — it is never uploaded, never in the browser, never in this website's code. You can also just drop in a CSV exported from TradingView or your broker.
