CM_Ultimate_MA_MTF_V2 with Alert Long and Short

Hello All,

Here is a scirpt of ChrisMoody modified with the alerts of purchases and sales.
I just have a problem with automation. At the bottom of my script my alerts "Buy1" and "Sell2" give alerts constantly and I wish to have a single alert before the order is completed. Before "Sell1" or Buy2 ".

I found the function "barstate.isfirst" that could possibly work?

Does anyone have an idea ? :)
