You can find the Triggers for all weekly events in the Trade Plans.
Each economic indicator will have at least one Trigger. Speeches and other non-numerical releases don’t have forecast values and therefore don’t have numerical Triggers.
Not all events will make use of all Trigger options. Some events require three Triggers to account for a maximum number of surprises. But on other occasions, two or only one Trigger may be enough.
The Next Trade is displayed on the very left side of the MacroTrader trade terminal, within the event prompt.
The FX Bolt EA has a Volume Parameter for each Trigger: T1_Vol; T2_Vol; T3_Vol. This way you can size your positions for each trigger level individually.
The higher the Trigger, the bigger the surprise and the stronger the anticipated market impact.
Note: An aggressive Trigger may receive decent follow-up while a safe Trigger may at times not. Always be prudent on your money management.
