I have a question out to their support for a couple days now about the fact that when a request is made about Lot Amount and Pip Cost, it is pushing back the incorrect values as discussed previously based upon the actual execution behavior. I updated the AssetList and using the Set_Patch broker command to use my values for the Lot size as being 1 rather than 0.1 and adjusting the Pip Cost 10 times higher. Will see how that works out. Will report back when I hear something from Oanda.

This is with the Oanda plugin directly. I do not know the behavior for MT4 nor MT5.
