my sugesstion is go through a lot of charts realtime and try and recognise market patters , the more you read technical analysis the more confused youll get read market pshcology , amrket wizards series is a good sart , the best is reminances of the stock operator
after a big move like yesterday some strength in opposite direction may be seen in opening next day like in YESBANK today(from 915 to 945). Trade in opposite(long for YESBANK) direction of major trend(down) should be avoided, if possible look for opportunities in major direction near S/R zones .
