salam Pooya khan. if this counting is correct, so ending diagonal structure has been ended and we have to wait for a reversal to upside, so price wont come to lower trendline again; MACD and divergence telling us that momentum is upside as we expect. but if this counting is incorrect, there is a possibility for another down move to lower trendline of channel and then it will reverse to upside. So because we dont know whether this counting is true or not, its better to wait for the break of upper channel, that is confirmation for a upside move.
good luck :)
