You said you have discovered this strategy 2 year ago and it works but you only take trade when the signal shows up strong. I want to know if you have been using just this strategy to trade only Bitcoin for that two years or you have use the strategy to trade other coins.
When I started trading years back, it was with indicators but now, I don't even trust indicators anymore because I believe it doesn't work for me again. Although, I have my own strategy that works.
