There was a problem hiding this comment.
Another place this can come in handy is when showing lot sizes during registration. For display purposes only, especially if they are paying their fees in a market's quote asset, we could show them a conversion based on the current price without needing to subscribe to the market order book.

If anyone else looking at this on the simnet harness, I'll note that testing is a pain because we interpret our 24 hour change from the 5-minute candles, so even if you put some action on the books immediately, it can take 5 minutes before you see a non-zero change. |
