Is is possible to trade PTS against BTC using gateway? I changed my base-counter currencies to PTS/BTC, (e.g. my BTC issuer is Bitstamp) , It seems that Ripple support to trade this way.
Would you please tell how will Ripple build the order book of PTS/BTC, and how will the background transaction be with PTS&BTC?
My understanding is that my counter must have the same currency issuer as me, right? e.g. I stored 40PTS in xrpio, and trust BTC, Sell 40PTS for 1BTC, my counter store 1BTC on Bitstamp, Bid 40PTS for BTC, when the trade are made, no need to move PTS/BTC between gateways?
