Better functioning MA indicator

I have the following two problems. My system works with changes in the MA indicator. So the trigger order is made by using the Moving Average indicator. When the candle is moving across the Moving Average indicator, there will be an order. My problem is, how can I change the setting that quickly placed a new order, see code below. And in addition, I would also like to see this MA indicator pictured in my system. Does anyone know how?
