Tradesignal at startup when there shouldn't be one

Actually it is not the program being confused but the conditions not being set/reset appropriately.
The enclosed revision of your script includes all 4 conditions and does not trigger any signals when loaded (or reloaded). Notice also that because condition3 and condition4 are now being reset they are never both true at the same time.
You can see this difference in the returns of the Formula Output Window. The bottom line is a reload of your original efs (which triggered the alert) while the top line is a reload in the same instant of the modified efs (which did not trigger the alert)
