MACD with level

Hi, I'm looking for someone to modify this already existing EA, I downloaded it from the database here at mq5.com. You can find it attached.

The expert advisor works only in backtesting, I could not indicate why it does not open positions in real accounts (demo).

I mainly need it to open positions. This is the first thing, so someone needs to check if the expert advisor can really work. I do not know the closing criteria of the positions already present in this expert advisor. I know there is but alternatively I would like a mm under my control.

So I would ask you to add a money management item to choose as an alternative to the existing system. I would like the possibility to choose a fixlot with fixed tp and sl and alternatively (true vs false option) a management percentage (1% to 100%). In other words, a choice between three items: default, fixlot, percentage.
