NSE:BSE
If BSE stock is going to have a downward trend then it has first support at 1920 and breaking it will further drive a downtrend. However, if it bounces back and retouch 1960 then a call position is going to be profitable and if it is breaking 2000, then it ain't stopping till 2200.
I would take a buy position, if it visits 1920 again after going down.
