Maximum Risk in that trade = 3 X 75 x 10 = Rs. 2250 ( around 3% of my capital)
Regarding Reward, My original target was Rs. 75. But, Market did not move in the downward enough ( PE price went to Rs 68, then it started to decline), hence, I have to book whatever profit I got. At least I got some profit. More Important: I did not loose capital, as, If I did not sold it at Rs. 65, My stop loss will hit (the lowest was rs.49) and I would loose Rs. 2250.
But My new understanding of preserving the capital worked today.
