Support and Resistance (Barry) indicator

yang Support and Resistance (Barry) indicator re-paints the final three bars. Particularly, when a assist or resistance stage is drawn, this stage first seems on the open of the third dot on that stage. It then paints this candle with a blue/crimson dot, and paints the 2 earlier candles on the identical time.

I want to edit this indicator in order that it contains an AUDIO ALERT, when a brand new assist/resistance stage first seems (on the open of the third blue or crimson dot/candle). I solely need the alert to sound as soon as, at the very same time because the third (assist or resistance) dot seems.

If anybody might help, i'm very grateful.

Thanks loads
