Betfair market anomalies

12/01/2012 | By More

An interesting couple of days so far this week in the markets. Interesting for an anomaly that we have seen. It’s only a couple of days old, so I can’t draw any conclusions just yet, but it is unusual so I thought I’d post about it.

We monitor the markets cloesly and ‘felt’ that matched bet volume on occasion was much higher than we would expect. We noticed this because, in the latter stages of a racing market just before the off, we were suddendly seeing very high per second volume. So this morning I had a nose at the data from this year so far.

In the last two days there have been three races each where volume was over one million. But since the start of the year, ten days, we have seen 20 in total. So that doesn’t seem stand out on it’s own, 20 vs. perhaps an expectation of 30.

But the the overall average volume has been much higher than normal, 123% of averageĀ on the 9th and 143% yesterday. I have deliberately rebased the volume to take account of different pricing that may distort the overall volume.

It’s difficult to know if this is a trend or some else is happening, but something changed over these two days. It could be temporary of there could be some other explanation, but we will be keeping an eye on it.

I left a good job in the consumer technology industry to go a trade on Betfair for a living way back in June 2000. I've been here ever since pushing very boundaries of what's possible on betting exchanges and loved every minute of it.
