Position sizing, options math, risk geometry and market timing — with real contract presets for Gold, Bitcoin, US30, MCX and NSE F&O. Nothing you type ever leaves this page.
Risk a fixed % of equity per trade — the single habit that keeps accounts alive.
Formula: size = (equity × risk%) ÷ (SL distance × value per point). Sizes for whole-lot instruments are rounded down — never round risk up.
Know your R before you click buy. Works for any instrument — just use prices.
Breakeven win rate = 100 ÷ (1 + R). At 1:2 you only need to win 33.4% of trades to break even — the math behind "let winners run".
What a move is actually worth at your size — before you take the trade.
Example: Gold moves $10 with 1 standard lot (100 oz) → $1,000. The same $10 with 0.10 lots → $100. Size is the throttle.
Breakeven, max loss per lot, expiry P&L and Black-Scholes fair value — for NIFTY, BANKNIFTY, SENSEX and more.
European-style Black-Scholes without dividends — an approximation for index options. Theta shown per calendar day.
The honest version: steady small months beat occasional hero months.
