What each order status actually means
An order moves through a short sequence. Knowing which step you are on tells you whether to wait or to look into it.
Waiting
The order exists and nothing has arrived. Nothing happens until your deposit is sent and seen. If you have sent it, check the transaction on an explorer.
Confirming
Your deposit is on chain and the network is confirming it. This is usually the longest step and it is entirely up to the chain.
Exchanging
The deposit is confirmed and the trade is being executed. Seconds, normally.
Sending
The payout has been broadcast. The transaction id appears here, and from that point you can follow it on an explorer yourself.
Finished
The payout has been sent and the transaction id is on the page. Save the page or the receipt if you need a record.
On hold
Something needs a person to look at it. It is not lost; it is queued for a human.
