Receiving an unsolicited email titled ‘Mastering exchanges: we’ll teach you to understand the principles required to be a successful trader,’ I’m about to file it in my special folder marked ‘trashcan’ when I notice a short biog indicating the signatory, Mr Clyde Wolpe, is a consultant for Betfair with over 15 years in the sports betting industry. A couple of mouse-clicks later and www.exchangepro.co.uk turns out to be advertising a new bricks-and-mortar training course, primarily looking at betting exchanges.

The £275 fee initially raises an eyebrow, but considering it’s spread over six hours – equating to £40 an hour – I’m thinking it’s a small price to pay if the course does exactly what it says on the tin.
