I have a strategy which needs to alert on the actual candle where the buy/sell signal occurs. By default Trading View only alerts on the next candle, so I’ve tried adding calc_on_every_tick which did what I need, however generated too many alerts in a row “Alert was triggered too often and stopped”

Note I’ve also tried with either freq_all or freq_once_per_bar

What’s the best approach to have an alert trigger during the candle where the buy/signal first prints?
Is my current approach the way to go, if so, can we code so the alert only fires on the first time and exit?

strategy(title='Combined indicators', shorttitle='COMBIND', overlay=true, calc_on_every_tick = true)

// Code continues 
............
//ALERT
if buyCondition and not buyCondition[1]
    alert(long, alert.freq_all)
    //alert(long, alert.freq_once_per_bar)

else if sellCondition and not sellCondition[1]
    alert(short, alert.freq_all)
    // alert(short, alert.freq_once_per_bar)
