Position Sizing & Risk
How much to put on, and where the line is
Position Size & Risk
Sizing
Works out how many shares to buy so a stop-out costs exactly your chosen % of capital — not a guess, not "round numbers". Quantity is also capped at what your capital can actually afford, even on very tight stops.

Risk : Reward
R-Multiple
Compares how much you're risking (entry to stop) against how much you stand to make (entry to target), as a multiple — a 2R setup means the reward is twice the risk. Also shows the win rate you'd need just to break even at that ratio.

Hard Cap
A hard cap, not a suggestion — the most shares you should ever hold in one name given your risk ceiling, capped again by what your account can actually afford.

Trade Expectancy
Edge
The average ₹ you'd expect to make (or lose) per trade over a long run of them, given your win rate and typical win/loss size. This is the single number that tells you whether a strategy has a real edge.
Win / loss rate50% / 50%
Expectancy per trade₹0
Expectancy in R—
Formula: Expectancy = (Win Rate × Avg Win) − (Loss Rate × Avg Loss). Positive means the strategy makes money on average per trade, before charges.
Expected ₹ per tradePositive edge
Drawdown & Recovery
Peak-to-Trough
Shows how far your capital has fallen from its peak, and the bigger % gain you now need just to get back to even. A 50% loss needs a 100% gain to recover, not 50%.
Gain needed to recover—
A 20% drawdown needs a 25% gain to recover; a 50% drawdown needs 100%. That asymmetry is why position sizing matters more than any single trade.
What it takes to get back to even—
Sharpe Ratio
Risk-Adjusted
Measures return per unit of volatility — a high average return earned with wild swings scores lower than the same return earned smoothly. Paste period returns; higher Sharpe generally means a steadier ride.
Frequency
Mean return / period0%
Std deviation / period0%
Sharpe (per month)0
Sharpe (annualized)0
Annualized via √periods-per-year (√12 monthly, √252 daily). Needs at least 2 periods.

Options Greeks
Black-Scholes
Prices an option and shows its Greeks — Delta, Gamma, Theta, Vega. Model estimate, not a live quote. Standard Black-Scholes for European options; real NSE options are American-style.
Enter spot, strike, days and IV to price the option.
Standard Black-Scholes for European options — real NSE options are American-style and can diverge near expiry or around dividends. Treat this as a model estimate, not a live quote.
European-style, no dividends—
Technical Levels

Classic Pivot Points
Levels
From yesterday's high, low, and close, computes today's pivot plus three support and three resistance levels — a standard intraday reference.
