I would like to use the EA at a time when there is no scheduled event. Is that possible?

Yes, you can adjust the EA times manually. This function can be used for the MacroTicks and MacroStraddle EA. Scroll down to the day or time parameters and adjust them according to your needs.

Please note, if you make use of the duplicate function of the MacroTrader, these parameters will be automatically reset to default for the duplicated strategy.
