This is clear cut triangle pattern breakout in Grasim,my view is buy after breakout at 488.
this is purely education purpose only shearing my view on it,not recommending to buy directly.
if you see bigger time frame 1 hr then you will see there is chart pattern breakout after that there is retracement is happening so my view is it can go down fast after crossing 886 and can go up-to 860 but depends upon market sentiments also if market is flat or bearish then can achieve the levels,sharing only my view for study purpose.
