I just downloaded some collected data from my VPS and thought I’d see how it compared to the Betfair Betting History. Coincidentally, the P&L since running on the VPS is zero, exactly. That’s after 11,500 bets settled across 2200 markets. I’ve only made very minor adjustments so far as I’m more interested in the amount of data I’m collecting – the more the better. Anyway, the data and betting history are well matched. Some discrepancies in the cancelled bets but this appears to be in how I’m capturing the greening trades, which doesn’t always include the sub £2 bets. It’s the bet modification that misses but I can code for this just in the greening procedure, so the fix shouldn’t be much and won’t impact the trading code.
