We own a floating week at KBC, and whenever we've deposited the week into II, we've just called Diamond and requested that our week be deposited without reserving a specific week for deposit. Can we ask KBC to reserve a high-value week such as Christmas and then request that the week reserved be deposited with II? Would that maximize our trading value with II? Not sure whether this is possible, but it doesn't seem like we are ever able to book trade for anything good, so that makes me wonder whether we have been doing it wrong.
