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.
Indicators are only a signal of potential market trends, whether bearish or bullish. This is just a statistic, nothing more. When talking about statistics, it will require analysis. You must understand very well how trading strategies are carried out using the wrong indicators in predicting trends. This is certainly not the wrong indicator, but maybe our analysis is not precise enough. If you find a suitable strategy, it indicates that the market conditions when you analyze are still stable, so your analysis can be in accordance with the trend.
Statistics are calculated from an analysis. It's not like I created it, this is how market works, since late 1700.
