Moving average cross-over signal with selectable alert?

QUESTION.
Does anyone know of a moving average cross-over signal and a separate moving average cross-over alert based on the IMMEDIATE crossing of two moving averages? This obviously will give many false signals for those waiting for confirmations, but for a scalper, it will be highly helpful as it can be used with other indicators to give a heads up for certain types of trade, REVERSALS in my case.
Attached are the only MA crossing signals and separate MA crossing alert that I have been able to find.
They fire too late to be of meaningful use, that is they only fire on completion of the timeframe candle. This lack of ‘meaningful use’ is directed at my own system and not a general comment.
Reversals are obviously the most profitable trades to get right and scalping within those reversals is a sound method of trading, that is scalping with the trend until there is a reversal – the perceived change in the trend.
Thank you in anticipation.

Trade what you see and not what you Hope.

Couple ideas.

If you're looking for the alert to fire as soon as the price crosses the line, just set the fast ema to 1 or 2.

If you're looking for the alert to fire as soon as the two MA's of choice cross, but on, say a 1 hour chart, it takes an hour before it rings.... Maybe set the alerts up on a lower timeframe like 5 minute or even 1 minute and adjust the value of the MA's accordingly. At least you wouldn't have to wait as long.
