Modification EA Tema_Dema_Self_Optimization

Good morning,

I have the Tema_Dema Self-Optimizing EA and I'd like to make two modifications:

Sample #1:

For example, I have a BUY trade open, the EA performs the specified optimization, and we get a new, different result for the TEMA and DEMA.

The EA performs a second, identical BUY trade, and from that point on, I have two BUY positions open.

I'd like to set a parameter that only one position can be open during a trade.

Sample #2:

For example, I have a BUY trade open, the EA performs the specified optimization, and we get a new, completely different result for the TEMA and DEMA.

The calculations indicate that a reverse SELL position should be open at this point, but my EA doesn't change this; it just waits for the next signal – a Tema_Dema cross.
