Everything a serious Indian trader needs
Log any trade in 15 seconds
Built for every Indian trader: intraday, swing, positional, F&O, commodity (MCX) and currency (CDS). Quick-add knows symbol, strike, CE/PE, expiry and lots — and multi-leg strategies (straddles, spreads, iron condors) carry per-leg entries and exits. Planned entry/SL/target give you R-multiples automatically.
Paise-accurate charges & an Indian tax pack
Gross P&L, every statutory charge (STT/CTT, exchange, GST, SEBI, stamp duty) and net P&L are computed per leg to the paisa from your broker's charge profile. At year-end, the tax pack groups by financial year with F&O turnover (ICAI), the speculative/non-speculative split and realised P&L per instrument — exportable as CSV, Excel or print-to-PDF.
The rules & mistakes engine
Write your rules once — 'risk max 1%', 'no trades in the first 15 minutes', 'stop after 2 losses'. Tick them off daily. TradeMarkk tracks adherence over time and prices every broken rule in rupees, so you can see your most expensive habit, not just feel it.
Insights, tilt & Monte-Carlo
Equity curve with drawdown, P&L calendar heatmap, win rate, profit factor, expectancy, R-distribution, and performance by hour, weekday, setup, symbol and direction. Plus tilt detection (revenge sizing, rushed re-entries, overtrading) and a Monte-Carlo equity cone — all computed in your browser, on your own data.
Broker imports & a multi-broker extension
Upload tradebook CSVs from Zerodha Console, Upstox, Angel One, Dhan, Fyers or Groww — fills FIFO-pair into round trips with charges applied and re-imports never duplicate. The companion Chrome extension captures trades and runs a pre-trade rules checklist straight from your Kite, Upstox, Groww, Dhan or Fyers tab.
Backtesting on real 1-minute options data
Replay your strategies against years of real 1-minute NIFTY, BANKNIFTY & SENSEX options data — per-strategy equity curves, expectancy, drawdown and walk-forward validation. It runs entirely in your browser (the dataset streams directly from a public archive), with honest data-coverage shown on every result. Build legs no-code with flexible strike selection (ATM±, spot-%, premium) and any candle interval.
Your data, three ways
Hosted (your own isolated database, managed by us), BYOD (your own free Turso database — we never see your data), or fully local in-browser. Switch anytime with verified, client-side migration.
