Short NZD CAD at Channel Limit

looking for a bearish stochastic crossover at the upper limit of the trading channel which has been well respected by price so far. The upward trend has had strong support so I'll trade this with a tight stop in case there is a continuation, will move to B/E quickly and will exit at the bottom of the channel or when there is a bullish stochastic crossover especially it it occurs at the 50 line. As ever comments, advise etc are appreciated. Cheers
