Nifty had formed a symmetrical triangle on 5 minutes time frame. If it breaks level of 17650 i.e breakdown of triangle can give us a 1st target of 17500 i.e 150 points and 2nd target of 17440. On the other side if breaks the level of 17800 i.e previous day high (PDH) can give us target of 17850 and 17970 levels.
