For bigger picture and context of what I am looking at have a look at long term charts first.
To start with, I plan my trades like I showed on the charts and this is not a direct trade signal, I will do that on my website when it is due next month. That's said I expect a correction for the USDCAD about to happen before we complete this weekly pattern for a wave C on weekly time frame.
On the 4 hour chart I described what I am looking for in terms of selling opportunities. I personally only enter a second position in the same pair once my first position is at Break-even but that's part of my risk management. Nevertheless look for breaks of the non-horizontal trend lines and ideally after a consolidation once we saw the break. This can be done on lower time frames as well for a more aggressive entry with a smaller stop loss.
Keep in mind that tomorrow we have FOMC on the agenda which might cause more volatility. Nevertheless the Technical outlook tell me that we should expect a retrace soon.
Once this wave 4 in Blue is over I expect another leg higher,this will be in line with another leg lower for oil and other commodities like Silver that are also bottoming according to my analyses.
