I wanted to trade some Bitshares currency pairs which I couldn't access through wallet interface on new Crypto Bridge DEX. Specifically I wanted to trade with OPEN.BTC : BRIDGE.BTC currency pair but I couldn't. There are only some predefined currency pairs. There are no "My Market" and "Find Market" options.
I found a solution and I would like to share it with you:
First, you should access to EXCHANGE option for any currency pair. If you look at the Internet address in your browser you will see both currencies in actual trade currency pair.
Example (BRIDGE.EOT : BRIDGE.BTC):
https://wallet.crypto-bridge.org/market/BRIDGE.EOT_BRIDGE.BTC
After that you should only change one of both currencies in browser's Internet address like this ...
https://wallet.crypto-bridge.org/market/OPEN.BTC_BRIDGE.BTC
... and you can trade with any to any currency pair. In my example that's OPEN.BTC : BRIDGE.BTC currency pair.
This can be done on any Bitshares DEX/Gateway like Openledger or Rudex.
To be sure, use the following notation for currency: DEXNAME.CURRENCY like OPEN.EOS, RUDEX.STEEM or BRIDGE.EOT
Buy and sell trade orders will only be possible if you have appropriate balance for at list one currency.
Happy trading!
