MA-EMA Crossover Alerts

This is a script for getting alerts for the MA-EMA XO Strategy that I published recently.
This is probably the first version that I am putting out for this logic.
Based on feedback (and some coding suggestions and support if anyone is willing), I will try to improve this further.
So, what do we have in this script -
I have created 5 alert conditions. The 4 alerts are straight-forward : Entry / Exit alerts for Long / Short.
The fifth alert is just a single Alert which is triggered if any of the 4 alert conditions are met. Then user can check the chart to see what trade is triggered.

I am not explaining the logic of the indicator here since it is kind-of covered in the strategy.
