Easy on paper only!! A strategy giving 300 points in a month may even give losses in actual trading!! The discipline, i.e fear and greed and use on a traders own intellect play a BIG role!!! SO its easier said than done!! You have indded done great!! If this be your monthly average just calculate the % return in an year!! Its toooooo good to be true....
A consistent 200 points per month and if one adds a lot of nifty every 3rd month, just see what he would be earning in a period of 3 years!!
These are all paper talks.. people who actully do it, probably dont have time to be here and waste time!!!
