I need a feature added to indicator 'TMA centered MACD v1 TT (mtf)' that is attached.

The feature will be the option to have an email alert (on/off).

When the email alert is on, the indicator will send an email when the TMA changes direction.

     The alert message will say: TMA has changed (up/down) on (currency pair)

It must only send one alert maximum per bar.
