What don't you understand?

Do you expect that the slow MA will just keep rising when price has been dropping?

Bro, the Price still go up, fast MA not drop down!

I call 2 MA with the basic code

MA300[i]=iMA(NULL,NULL,MAPeriod,0,0,0,i);

MA300slow[i]=iMA(NULL,NULL,MAPeriod,-40,0,0,i);

Please don't call me "Bro"!

You obviously don't understand how MAs work. Study them.

Your new image is showing a shifted MA, not a slow MA.
The vertical line looks like a trendline.
