DOUBLE DUTCH

Double Dutch is an Excel spreadsheet costing £34.97 and marketed by Steve Davidson. It works on UK, Ireland, South Africa, New Zealand and more. For a market, either a horse race or a football match or whatever sport you want to use this for, you enter the odds of the various possible results. If the result is viable, the spreadsheet calculates your stakes using one of two stake pools.
