On second thought, I may suggest this alternative strategy. It may be safer than timing the market. You fix a price target and if the price moves beyond it, move the stop loss level along with that move in the direction. Though you may not get the top most/bottom price, still you will get good price. Let some one else also to make money. Do not think that "Mera Sapna Sabka Mal Apna". That motto is for Reliance. Not for us.
