We have a few systems that we would like to backtest for Betfair. So this job is programming those systems, and testing them out. You will need to have a background that includes both betfair and statistical analysis. The systems are not very compllicated, but you will need to know how to program them and test them thoroughly. This is an interesting job for the right person. The hours are flexible and you can work as and when you want.
You can probably do the job in Excel or Ninjatrader or another of your choice.
