Hi Nicolas, yes I agree. I already wrote them, but couldn’t hurt to ask if anyone experienced similar problem. I compared the code to a a similar one, that does execute, and only thing I could find is I have coded a time frame for trading. A very simple one. Seem very odd that is should generate a rejection, but let’s see what the reply will be. It’s on demo account.

IF (Time >= 08000 AND Time <= 220000)then// OR (Time >= 130000 AND Time <= 170000) THEN // no trading during lunch
Tradetime=1
else
Tradetime=0
endif

IF Not LONGONMARKET AND longcondition and tradetime THEN
BUY PositionSize CONTRACT AT MARKET
ENDIF

// short
IF Not SHORTONMARKET AND shortCondition and tradetime THEN
SELLSHORT PositionSize CONTRACT AT MARKET
ENDIF

Thanks Nicolas. IG came with a respond. I will post it here for future references.
