time form cash out hints

The 'Cash Out' facility on Betfair is NOT fast enough to cope with the furious speed of the ever-changing 'in-running' odds/Markets on Horse Racing.

You will/would never get matched - and most especially at the mythical, and false, amounts that Cash Out occasionally displays.

Cash Out is purely for slower moving Markets - like a Football Match - where the prices merely move a couple of ticks at a time.

Of course - you could continue using a pre-set price, put into the 'In-running' market - or similarly, a 'Keep' Lay - as the Markets turn 'In-Play'.
