Charges for entry and exit (per lot, in BNF Futures)
₹40 goes to broker
₹52 to exchange (NSE)
₹338 goes to Government
Total - ₹430.93
Worst part is, broker will only make ₹40 even if you trade 10 lots, but government will make 10x money (if you trade 10 lots). Charges levied by government are on per lot basis and not per trade.
