Yes, if the Minimum number of trades = off, then the optimizer produces zero trades. I got results when I switched Minimum number of trades = on.

I tested several times, but then I got this kind of situation:

I had to manually set minimum strating values into the default indicator dialog to get it working rightly.

This moving average crossover is intended to be the trade direction and trend filer to prevent trades against the main trend.

I agree that this is a bad idea to optimize loosing strategies. I use limited optimization at the beginning of the strategy development. I have found that it's reasonable to optimize only 1-2 indicators in the strategy.

I included my unfinished strategy idea. I used 250 000 bars of data within the optimization.

The optimizer sets equal number in order to prevent trades. It seams no combination of the selected parameters can lead to a winning strategy.
But this must not happen if "Minimum number of trades" is set to some number.
If your case is not this, please attach the strategy and your config file in the forum. I'll check it.

Hi Popov

There is a strange behaviour in Optimizer. I tried to optimize this indicator with the option: fast MA > slow MA:

Then I got a zero strategy. Both fast MA and slow MA values are the same (21).

I tried this several times.
