Alert for combination of 2 existing indicators

[Guilherme Guimaraes Dias]

Is it possible?

I would like to create an alert, for when the combination of the two indicators show the arrows simultaneously on the same candle.

The alert will be output according to the arrows.

I don't have the .mql4 files for the indicators, just the .ex4.

You don't need the source files. Write an indicator. Just get the value(s) of the indicator(s) into EA/indicator (using iCustom) and do what you want with it.

You should encapsulate your iCustom calls to make your code self-documenting.
