Strange ! I already have this test PaireDevise[i]<>'' and have to add Bid*Ask>0 to be sure no bid or ask price equal to 0 ?

if (TradeOK = true) and (PaireDevise[i]<>'') and (Bid*Ask>0) then
begin

if SendInstantOrder( PaireDevise[i], op_Sell, LotToTrade , NewSL, NewTP ,Commentaire, MonMagicNumber , OrderHandle) then

Philippe,

Please add "Print(PaireDevise[i]);" log, maybe this will help you to find a problem.
