After I　bought or sold TMSC by wallet exchange when testing , I checked my address in bitcoin block explorer, I got this message as follow
1EXoDusjGwvnjZUyKkxZ4UHEf77z6A5S4P 0.00006 BTC
(Escrow 1 of 157rMRZUve... 1PJCYPLdjP...) 0.00018 BTC
I'm confused with the Escrow line,could you please tell me what does it mean,where did the 0.00018BTC go to?
In addition,when buying or selling TMSC using wallet p2p exchange,I cancel my transaction,but I　still have to pay for 0.00035BTC . I don't think it's reasonable.

The 'Escrow' is actually a multisig address. It's what we call "Class B transaction" - see the spec. You need not worry about it, it's just an implementation detail.

Regarding canceling orders - any action that changes the state of the DEx needs to be broadcast as a bitcoin transaction - there is no way to do that without paying the minimal transaction fee. Note that 0.00035BTC currently equals about 22 cents.

The DEx does not work like centralized exchanges, it has benefits and downsides. One of the downsides, unfortunately, is fees that needs to be paid per operation. However consider when buying large blocks on the DEx, you will not pay a relative fee, but rather just a fixed amount - so it should end up cheaper (not to mention you don't need to trust an exchange).
