Re: Do exchanges let you fill your own order?

This scenario feels pretty weird to me, I don't think it makes sense for the exchange to forbid the sell order from being submitted, but I also don't think it makes sense for it to execute the trade. What is the expected behaviour here?
Of course, it's weird and will most likely never happen in reality. However, as Royse777 said, these are 2 different orders, so I assume that the exchange also places them (and has them fulfilled). I would not know that Exchanges check the orders of a user among themselves for consistency.

You could of course try this yourself by placing sales with fractions of BTC and purchases with very small amounts of USD. However, as I said, I assume that these will also be fulfilled.
