Had a couple of YM mkt. buy stops fail to trigger on Friday afternoon. First time ever having any problem with IB & stops. Anyone else with IB weirdness on Friday afternoon?
When I tried to place an order late friday afternoon, TWS gave me the message that the order would not be placed at the exchange until a certain date / time. Don't know the exact date / time, but my guess is that the ECBOT didn't accept stops because of the holidays... I was able to trade however, so my guess it that it was only affecting NATIVE STOP orders
They are simulated since A/C/E was replaced by ECBOT. For simulated stops there is a default setting: "regular trading hours" (AFAIK defined as 9:30 am to 4 pm ET on "regular trading days"). If you want to avoid trouble with "regular" trading hours" then you will have to change your TWS settings. See TWS Configure / Order / Stop Trigger Method / Time Restriction BTW, last Friday was MLK day (not a "regular trading day") and simulated stops were already inactive before 4 pm ET (with the default setting).
