Hello New Digital or others,

Has anyone come across an indicator/expert that sets off a sound and pop-up alert (1 time only!) when the close of a price bar crosses an MA? It seems like a basic function but all I've seen are alerts for two crossing ma's. For my use the ideal would be the basic Moving Average indicator in the basic MT4 Indicator folder, but with alert functions added.
It would be excellent if it was also possible to have an alert sound when a moving average level is crossed. For example one chooses a 50 ema, (close) with Levels set at +/- 30 pips. The alert could be set to go off when the price close crosses the 50ema, and/or when it crosses the -30 or the +30 level of the 50ema.
If anyone has seen such an alert I'll appreciate a 'heads up'. If someone is willing to program it in .mqh that would be excellent.
Thanks,

-MJ
