I don't think anything like that exists yet, but it is definitely needed. People are using the BTER price as an argument that the market peg is not tracking accurately in some of my debates. Obviously all of the market depth and liquidity is on the decentralized exchange, so we really need something like this to easily track how well the peg is working. I would venture to say it is tracking much better than if you were to only look at the BTER chart and form your opinion.
Exactly. BTSX is traded a lot on bter, and every time the bitUSD price spikes one way or the other due to lack of liquidity there, everyone thinks that the peg has failed and starts dumping BTSX.
We really need a solid chart of the price, in USD, representing the highest volume trading that is occurring.
