Would it be possible to allow traders to switch to a different view of the bets where not the price of the last made transaction is displayed, but the lowest bids to buy from and the highest bids to sell to? For the bet "Will Jon Tester be re-elected to the U.S. Senate in Montana in 2018?", you wouldn't see on 2018-03-06, 23:24 CT
but you would see something like
Yes 70 - 75
No 25 - 30
That would both signal the liquidity of the market (not high for Tester) and the possible trades to be made. The price of the last trade made should be available, of course, but not dominate the display.
