GBPCAD is currently facing multiple MA trendline resistance (20MA daily, 200MA 2H, 1H and 100MA 1H) so if market is not fierce it should respect the technical indicators just a bit :D
Overall GBP is not out of it's downtrend at all so let's be careful about this setup.
SL: a few pips below any of the MAs, I set it rather low, it can be as tight as 1.738 if you wish to take the risk
