setting up alerts

I have done quite a bit of searching but can not seem to find what I am looking for.
Is there a tutorial on how to set up alerts with mt4? I have found some on setting up for backtesting but am more interested right now in learning about setting alerts for ema crossings which simultaneously occur with certain indicator levels.
Any help would be appreciated . thanks

I doubt that you can simply set alerts the way you you describe it. I think that you would need to have te alert programmed into an indicator. I might be wrong.

I applauded alertfx dot come in another post simply because it can not only send simple price alerts.....BUT...it can also send on some techincals including crosses of ema. I have not used nor tried it for that however it is free to use so is worth a try.
