Recent High/Low Alert

Hello. I'd like to ask if it's possible to make a small change to the Recent High/Low Alert indicator. The indicator now triggers the alert every time it touches the low or high, the lower or upper line. This way, the alert sounds on every candlestick and every low. I'd like the alert to sound only once, the first time it touches the upper or lower line. There shouldn't be a new alert until the opposite line is touched. https://www.earnforex.com/indicators/Recent-High-Low-Alert/

Why not set the TriggerCandle to Previous? That way, you will only get the alert when the candle is finalized.
