Portfolio Greeks and stress test

Portfolio Greeks

Open Portfolio risk. It adds up the Greeks of every open position, per account, per group, per underlying and in total. It refreshes every 10 seconds.

• Delta (units): how many units of the underlying your positions behave like. For example, +65 on NIFTY moves like one lot of the index. Positive means you gain when the market rises.
• Delta exposure (₹): delta × the underlying's price, so different underlyings can be compared.
• Gamma: how much delta changes when the underlying moves 1 point.
• Theta: ₹ gained or lost per day as time passes (negative for bought options).
• Vega: ₹ gained or lost when implied volatility rises by 1 point.

How positions are valued:

• Stocks and futures count one-for-one with their underlying.
• Options use Black-Scholes. The implied volatility (IV) is worked out from each option's own price. If an option's price has no time value left, the platform's IV model is used instead, marked with *.
• Real broker accounts are valued only from your broker's live prices. Without a live price, a position is listed under Not valued and left out of the totals.

Stress test

Choose an underlying move (for example −3%), an IV change (for example +20%, meaning IV × 1.2) and days forward, then press Run stress test.

You get:

• the estimated P&L per account and per group, and for the whole portfolio
• a grid of P&L for moves from −5% to +5% against IV changes of −20%, 0, +20% and +50%

Every option is revalued with Black-Scholes at the new price, IV and date. Stocks and futures move with their underlying.

These are model estimates. Real prices can differ, especially in fast markets or near expiry.
