COROMANDEL INTL - trading at lower line of the channel

The candle on D and W closed right on the line, so one can expect reversal.
There is also an Ascending Triangle forming.

Logically one may want to short for the next support.

But I would like to go Long with SL below yesterdays low 775.5

Targets
T1 - 50% of channel retracement
T2 - Once it breaks out of the triangle - take next resistance 862
T3 - 880
