Reckon liquidity has dropped a bit.
Price has drifted a bit as well - not enough to stop using match as long as it doesn't get worse.
asians are a bit hit and miss as well - especially lacking on -0.5/+0.5 markets - guess you are favouring comm payers instead and are putting up splits instead.
beta (or current iteration) site is poorly designed for navigation and clarity of overview.
Old site much better (though not great in this respect)
