Create an EA for crossing moving averages

I need a simple EA that performs inputs and outputs according to the crossing of moving averages. It should operate with 03 moving averages, as follows:

Sales Order Entry: MA01 crosses MA02 Down
Sales order output: MA01 crosses MA03 to high

Purchase Order Entry: MA01 Crosses MA02 Up
Purchase order output: MA01 crosses MA03 down

The inputs and outputs must be performed according to the current price, it is not necessary to close the candle.

This EA will not work with Stop Loss or Take Profit, because all inputs and outputs will be based on crossing the averages.

Thank you!
