But overall I prefer to rely on trends and patterns that reflect the big picture nobody can willingly amend.
Perhaps there is another field where your idea may be right: Shares. I think markets of shares can be easier be manipulated as the volume is not so large and there may be this or those trader in the big factory hall trading rooms who does it regularly.
I wish you good luck!
But on the other hand CAD is laging AUD and NZD, which means we could see a much weaker and violent CAD when traders turn their attention to the CAD.
For now, I've a very very small long GBPCAD, but longer term it could rally big.
