This was mentioned in that previous thread that ktm posted for you. There will not be a cancellation charge for a simulated order, which stands to reason since this charge is not an IB decision but a charge coming from a CME decision; a stop order is a simulated order for the CME.
I don't know why this has come to be, it will effect my trading minimally and only when I have entered a limit profit target that doesn't get filled and another price or exit has to be done instead. I do think I like this idea if it can remove some of the "noise" I feel when trying to get a sense of a lot of bid-ask changes and size shifts from the bid to ask or ask to bid and very few corresponding trades.
