Head & Shoulders 4H Chart USDCAD 03/12/2018

As we can see on the 4H chart, there is a potential that the price will create a Head & Shoulders pattern, If my prediction that I marked on the chart will come true, we will see the Head & Shoulders pattern up there, the reason I'll sell at the supply above is not the pattern, I'll sell at this supply because it's a level with unfilled orders waiting there for the price To come back, Also, this supply has changed the bullish momentum to bearish, this supply created after this week starts with a GAP at the price, I'll sell high and buy low, meaning, I'll sell at the supply and my target will be the demand below.
