Maybe not the slots are back up and working

Most of the other exchanges leech their prices from Betfair so if there's no prices on Betfair they can't price up. I looked at smarkets for the next race and the spreads are ridiculous a spread of 9 - 11 on Flying Sahkee and at least 3-4 ticks between the others with less than £100 liquidity at the front prices
Me too... I've come out of it £5 up when I was expecting to be either £6 down or breaking even. It looks like in the confusion I traded once more than I thought I had.
