Using indicators to filter entry/exit points only make a fixed set of available trades in which to quantity trade statistics. If trading is a career, you’re going to take a lot of trades. If using indication based on historical prices, you’re hoping for a system that follows it’s expected value closed… without volatility.
Ie; Strategy A that wins 20-49% of the time at a R-multiple of 2. vs Strategy B that wins 30%-36% of the time at 2R. When the expected win rate would be 33%.
It won’t be the expected value that loses an account, it’ll be the imbalance of the distribution for wins & losses.
I’ve noticed this when buying a sell signal & selling a buy signal that yielded the same results.
I personally don’t use any indicators.
