See my weekly video on the analysis i did on this pair.
As you predicted the pair to fall but it obviously went the complete opposite way so not only did you lose money on that trade but you got caught up in the pattern and missed a good long trade.
If they work for you more often than not and you earn money then good luck, its just my opinion.
Its very hard to pick tops and bottoms in the market and thats what they seem to be.
I trade with the flow and trend and Ive just come out of a losing streak myself so I'm well aware of the effort it takes to be consistent.
We could speak to 20 different traders and all trade their own way with success in their own right. good luck , if it isn't broke then don't fix it.
