AVANTI looks highly overstretched. Buying at this levels not recommended. A close below 340 on weekly charts can trigger a fall which can be very string and fast.
Wait for 180-220 levels and after that lets take a decision wether to buy or avoid.
AVANTI Feeds channel (study purpose only)
Avanti Feeds is currently trading in the lower half of the rising channel and bulls need to be careful at CMP (2540+) and accumulate only on dips until the channel bottom.
