So the calculation goes like this...
Say you bought 10 lots, total margin paid: 2,50,000 (assuming 25000/- per lot)
Total Profit = 1,800/-
Brokerage Paid = 700/-
Now assume you got one SL hit.. so the SL should be less than your target, right? say its 2 points + 1.4 point of brokerage
Loss = 1700/-
You are ready to risk 1700/- for a profit of 1800/- while the actual capital at risk is 2,50,000/-
Actual risk reward is just 100/- for the total capital at risk of 2,50,000/-
