IB TWS - Creating limit orders with pre-defined offset from last price

[TraderZones]

Quote from jpatet:

I too would like to use these user-defined offsets. But I also need to use the Good After Time and One Cancels All functions that are available on the order ticket for the same order. It seems that the offset functions are not available on the Order Ticket and the GAT/OCA functions are not available on the hot keys. Why wouldn’t these offset functions also be available on the Order Ticket? Anyway, I suspect this may be achievable somehow in TWS. Can you help with this?

I believe you cannot specify user defined offsets for futures where you just say get me in at a stop/limit/market at some price X +/- Y ticks, at least for entries...
