Custom Moving Average Cross

Can someone create a moving average cross alert based on the custom moving average,

  1. An Alert with sound that will let you know that a cross has occurred between the moving averages, for example 21 and 90.

Thanks

so you’re looking for an indicator but not expert?

if so, here is an indicator, it’s called MA_Cross_Over, I found it on the MetaTrader_Experts_and_Indicators group on yahoo…

Hope this is what you need
