Hello,
I found your signal intresting.

Is it possible to add a sound alert when a signal change its status?

It would be great

Thanks
Jeff

To play the sound when signal appears just specify true in the parameter Play Sound (the parameter before the last parameter of the signal, false (do not play sound by default)) and choose a wav file to play in the Sound File parameter (this last parameter).

Hello Nikolay,

i use the VoltyChannel Stop Signal on higher timeframes to confirm TREND CHANGE - would it be possible to add an EMAIL ALERT function to the signal - this would be very helpful !

Thank You very much

Oktoeight

Added to development cue.

Email functionality is added.

BTW, I don't think that we should support it anymore. VoltiChannelStop strategy does exactly the same in case 'trading mode' is off.

Thank You very much !!

- i just saw the Volty Channel Stop Strateegy today - will use this for sure..

Great Work !

Hi Nikolay, this is not an indicator but a signal, in fact the trading station gives me the error loading, please can you develop for this indicator the corresponding signal? I would be grateful. Thanks for everything. Luigi!!!
