If it sustains above upper line of channel i.e. near 24.5 - 25, one can enter long with sl at 23 and trail with sl.
13DEMA crossover with price action from above will be a sign of bearishness and a good exit point only if this creates a rally here.
NOTE: This is my view about this stock, please analyse on your own before trading it. I haven't considered G.S.T effect in this.
