Coding needed for EliaSystem

Hello everyone, I'm using this trading system for about a month, Renko 10 PIPS SYSTEM SIZE try some programmer for an expert advisor that opens a buy order when the price breaks the 21 Ema and closes in profit when the price touches the 21 Ema, opens a sell order when the price breaks the 21 Ema and closes the order when the price touches the 21 Ema, as in the picture

if you need the indicators you ask and I'll share them

I'd also like an indicator that warns me with email when the price closes below the EMA 21 or closes above the EMA 21
some programmer who can do this indicator?
