Hi @VAggarwal
To show return in terms of percentage at an aggregate account level is mathematically challenging. I will explain how.
To calculate percentage return (or any type of %) the formula is:
% Return = {(Final Value − Initial Value) / Initial Value} × 100
Now, for an individual holding (a stock in your portfolio), this is plain and simple. We know your initial capital deployed and the current value of the investment, so it is easy to calculate the return. This can also be extended to the aggregate sum of all holdings in a portfolio by taking the total invested amount as the initial value and the current portfolio value as the final value. That is why you see percentage returns shown clearly on the Portfolio page.
However, the same logic cannot be applied to positions (trading). In trading, capital is continuously reused and rotated. Funds are added and withdrawn, positions are opened and closed multiple times, and exposure keeps changing within the selected date range. There is no single, well-defined “initial value” for the period.
For example - You may start the month with ₹1,00,000. Deploy only ₹20,000 for a trade, exit it, and reuse the same ₹20,000 multiple times. Add more funds mid-month or withdraw profits. Carry forward open positions from earlier periods
In such cases, calculating a percentage return using a single denominator becomes misleading. Any percentage shown would depend heavily on which capital base is assumed (starting balance, average balance, peak exposure, etc.), and different assumptions can produce very different percentages for the same P&L. This is why showing a % return for trading positions, particularly at aggregate account level can easily misrepresent.
That is also the reason why most professional trading reports focus on absolute P&L, realized/unrealized P&L, rather than percentage returns.
In contrast, for investments and portfolios, capital is generally deployed with a longer-term intent, holdings are relatively stable, and the initial value is clearly identified.
Hope this helps.
