is the indicator that you're referring to the RSI? intuitively, what does it mean when price is making lower low but the RSI is making a higher low? what is fundamentally happening here?
is that the 5 minute chart you're posting? can you define bullish divergence more clearly? if you change the scale of your charts then the divergence will "look" either weaker or stronger.
so you bet big on those 3-4 trades and your returns are due to you being right on those trades instead of compounding?
what are your drawdowns in terms of equity curve?
