Equity curve trading is not so hot topic these days, but there are traders who are profitable using it's techniques!
I'm using EC trading to smooth my overall equity curve. These two blue line are calculated just like Ichi cloud lines but they use average of hl2 instead of median!
In long-term 20 years back-tests breaking this kind of cloud reached a satisfactory level of profitability but note that it's not always activated in all pairs.
Considering rules for activation and deactivation this trading setup reached around 30 percent win rate, which makes it profitable regarding to it's good R to R ratio.
NOTE: indicator based strategies are not always active and do not work in all instruments.
