Built a free F&O analytics dashboard because Groww's P&L page wasn't enough

If you trade F&O on Groww, you know the P&L page gives you a realised P&L number, a contract-wise table, and per-contract charge breakdowns if you click in. But there’s no overall view, no win rate, no risk:reward, no aggregate charges breakdown across all your trades, no way to spot patterns over time.

Wanted to actually understand my trading performance, so I built a free tool Growwzy. You upload your Groww F&O P&L Excel (the one you download from the P&L page) and it gives you:

• Cumulative P&L timeline
• Win rate, profit factor, expectancy, Sharpe ratio
• Full charges breakdown (STT, brokerage, GST, stamp duty separately)
• Calendar heatmap of daily P&L
• Script-wise and day-of-week performance

Everything runs in your browser no backend, no data leaves your machine.

Only works with Groww F&O reports for now.
Would love to know if this is useful or what metrics you’d want added.
