Hello.

Some suggestions:

- First try the system without any filter at all, compare results.
- Then use a simple moving average filter for determining trend, just something like price > sma or sma > sma[1], compare results.
- Give MMI a try as stated in WorkShop6.

Sometimes this works better than other more elaborated models. On the other hand, trying to filter flat periods is not easy, you are most times better off just diversifying on assets/algos or just using phantom trade.

Also, maybe you are using the right strategy on the wrong timeframe/asset. Try a portfolio of assets and compare performance.

Greetings.
