Weird and interesting at the same time. But the result is that your treasury is still empty. You probably have the wrong prices set for your services.
Based on this, it seems as if you are angry at eXch because they don't have enough XMR to cover the demand, while you don't see the problem in the fact that most other exchanges have stopped XMR withdrawal
With your displayed 24h volumes (which are absolutely unbelievable) - you are the biggest exchange on the market (with an empty treasury - ironic). So the price of Monero is set (according to you) mainly by you. There is obviously some mistake somewhere.
It may be hard for you to believe, but there are probably even now some open orders waiting for new funding to be executed. I challenge you to prove your theory, sell 1000 XMR on eXch and watch how long it lasts.
