Here will explain that strategy which have 95% accuracy win rate and require 1L capital . You can expect 5% return per week. I traded for almost 3 months and working good.

Entry trade Every Friday morning 9.30 :-
when bank nifty spot at 39200 deploy call debit and put debit spread.
Call debit spread:
spot: 39200
Buy ce leg : 39600 --> 400 points above
Sell ce leg : 40100 --> 500 points above ce buy leg
Funds needed 25k

Put debit spread:
spot: 39200
Buy pe leg : 38800 --> 400 points below the spot
Sell pe leg : 38300 --> 500 points below pe buy leg
Funds needed 25k

For deployment these two strategies required 50k. Expecting 5% on capital of 1L means 5k.
Case 1: If market went up when you see min 5k profit on call debit spread book call debit spread . Now you have only put debit spread means 38800 pe buy and 38300 pe sell .

Now sell 2 lots more of 38300 pe and buy 37900 pe 2 lots . Now you have put butterfly 1:3:2
38800 pe buy - 1 lot
38300 pe sell - 3 lots
37900 pe buy - 2 lots
so that your making loss free of put debit spread and booked profit of call debit spread.
