Create a indicator that can detect M pattern or W pattern with the interaction of the 13 EMA

I would like to develop a indicator  to help identify M orW patterns  

W - Price come from above 13 EMA  to below it and close to create a 1st leg 

Price then rally up and close above it to make the Apex 

Price then drop below 13 EMA 

All must be closes above and below 13 EMA 

And maybe we need a minimum. no of pips per leg 

Then rally and close above it and give us an alert that the W pattern is complete on the m15 time frame

The inverse for a M pattern 

I think it would need a few filters 

pattern usually happens after ASIAN session and between london and NY session 

and normally forms at Low of day  W or high of day M

or Previous days low or high  the 50 EMA or the 200 EMA  Sometimes it can also form at the Average daily range projected high or low also 

I guess i could monitor these things manually 

Not all legs are always equal either .... 

I could also set the indicator manually if needed as per if to look for W or M etc 

We can discuss 

The aim is to help keep me away from the chart a little bit  I am trading Market makers method 

I already have a template i use for my trading for mt5 which i have made which also shows the Highs and lows of day etc if that is helpful ?  Maybe it can be added to the template...
