First fix a target say to earn 5% of ur capital per month(10% per week is not a realistic goal)in the beginning.That is 7500 monthly or 7500/20=375 daily.
or you can fix traget point wise say 10 points per day after brokerage and slippage.
Remember Money cant be made daily in the market so have a favourable risk reward ratio so that you win at the end even if you have more losers than winners.
You can extend ur target step by step after achiving this one.
Dear one bull
10% per week is impossible i assure u that.Even if u make 8% in a month consistenly you are counted among a few handful of successful traders in the world.
