I added FAST below with the same error.
Do you have an example please.
Thanks

function run()
{



StartDate = 2005;
EndDate = 2015;
BarPeriod = 60; // 1 day
BarZone = WET; // Western European midnight
Weekend = 1; // don't merge Friday and Sunday bars
LookBack = 3; // only 3 bars needed
NumWFOCycles = 10;

set(RULES+TESTNOW+FAST);
