I tried to understand & use the COMM table , but it s bit contradictory while , if try to understand tick wise PNL , for example Natural gas MCX contract specification is , Trading unit 1250 mmBtu , tick size minimum price movement 10 paise ( 0.01 rupees ) so according to MCX for "1 tick " movement PNL is 1250 x 0.01 = Rs 125 , but as per Zerodha Profit/Loss for every 1 Rs change
for Natural gas is Rs 1250, so some times its difficult / confusion to understand per tick PNL , so i would like to suggest if you can simplify it as Profit/loss for 1 tick movement instead of 1 Rs change will be of very helpful and easy .
