This is what happens, when you go after some one's apparently winning strategy, without trying to learn. One day he disappears, for whataever reasons. AND EVERYONE IS LEFT DEJECTED.
Better try to develop your own simple strategy and follow them religiously.
Pick any two stocks from Nifty50 based on news/ rumour, charts, analysis, whatever,. and track them after 15 min bar. Buy, if brakes above. Short, if brakes down. and apply money management. With discipline you will come out winner.
