Exact all-in cost per trade — brokerage, STT, exchange charges, GST, SEBI, stamp duty. Most traders underestimate this by 40%.
Why this matters: On a ₹7,500 options position, you pay ~₹55 just to enter and exit. That is 0.7% cost before a single rupee of profit. Trade 10 times a day and you need ₹550 in profits just to break even on costs alone. Fewer, higher-conviction trades win.
