ha? why would I use a service for exchange when I can do the exchange in the market myself?
What's the use-case here?

This is factually really big. I had been hoping someone would make something like this, as it's a vital piece of infrastructure.

The light wallet cannot trade on the DEX. With a bridge like this then all light wallets have access to easy trading with market orders. Once the system has proven reliable I think the best of these services should be incorporated directly in the GUI of the light wallets. Over time a rating system and alert system can be put in to reduce risk, but at first our focus should be the immediate UX benefit this service has over using the DEX directly for casual traders.

Awesome work! Once gateways join into Bitshares, their IOUs can be added in your exchange.
The site is very simple now... maybe needs @cass 's hand?

PS. Can you add price switching button?

yes, I should ask cass's help early. wish he still have time, so many project need cass.
I have much more tasks to implement at this exchange,
there will be heavy  work at web development

This is a great tool for lite wallet clients.   the speed with which things are happening and coming online has me very excited.

I don't know how to sent return and change in a single transaction, can you tell me? that will be very helpfull

Oh, I assumed you already knew how to do it because you did it with the bid and ask orders with BTSBOTS (https://bitsharestalk.org/index.php?topic=12289.msg164521#msg164521). But I see that the wallet_market_batch_update command only applies to market orders.

I am confident that the blockchain supports an arbitrary number of deposit and withdrawal operations within a single transaction (as long as the transaction size doesn't exceed limits), but I guess there isn't support to build such a transaction through the client RPC interface as of now. So it is in theory possible to custom build a JSON of such a transaction, then use the wallet_builder_add_signature command to sign and broadcast it, but that is a lot of effort so forget it (unless you want to!). I also wonder how the full client would visualize such a transaction in the transaction history.

How do you determine how much of the order to fulfill (and in what time limits)? I noticed that a lot of the orders with GOLD are partially filled (presumably because those markets are not very liquid?) and the rest is returned as change. Also, what do you think instead combining the partial fill returns and the change into a single transaction, just to make things simpler in the user's transaction history (plus it saves you an extra transaction fee)?

that's for test, I set the  max limit to 3 CNY at that moment. now I have change the limit to 100 CNY.

How do you determine how much of the order to fulfill (and in what time limits, since I noticed wildpig's gold order took 8 minutes to partially be fulfilled)? I noticed that the orders purchasing GOLD with USD are partially filled (presumably because those markets are not very liquid?) and the rest is returned as change. Also, what do you think about instead combining the partial fill returns and the change into a single transaction, just to make things simpler in the user's transaction history (plus it saves you an extra transaction fee)?

next, I'll try to find the best price order from wallet market, connect the market and  this exchange service.

Go for it!
