Select symbol/timeframe you're interested in, add this script to chart and then you will be able to select these custom alerts in create alert dialog.
if those text not showed up, the alert also not triggered.
Am I doing something wrong? I already set up the alert to:
1. Kozlod - Parabolic SAR, PSAR Long, PSAR Long, Once per bar --> for long signal
2. Kozlod - Parabolic SAR, PSAR Short, PSAR Short, Once per bar --> for Short signal
at those 2 red X, the alarm didn't triggered
