Clarifying "Once per bar" and "Once per bar close" alert optionSince I can't find any official documentation about this, I am posting this to help others like me who struggled sorting this out.
When creating an alert, be it a custom alert or not:
- "Once per bar" will not wait the bar close to trigger the alert. If the condition is triggered once but ends up to be false at bar close, the alert will have triggered but will not show on the chart and backtest.
- "Once per bar close" will wait for bar close to trigger the alert. With this option you are sure to stick with the backtest and avoid less strong signals, but waiting for bar close might reduce profits.
