betfair imposed delay & exposure exceeded

[littlebazz]

When backing in running i have started getting a message in red on the bttm of the screen counting down from 3 saying delay imposed by betfair, when it reaches 0 there is a message of error placing bet exposure exceeded.
I am backing only and the stake is less than half of the account balance, there is also no exposure on other markets, i have very little knowledge of BA & use it for backing in running only but have never had a problem with single click backing before, any help greatly appreciated

Hi,

Betfair impose a bet delay on in play markets which for horse racing is 1 second.

See http://betfair-en.custhelp.com/app/answers/detail/a_id/2667/kw/bet%20delay/

The fact that you are seeing a 3 second delay suggests that you are using below minimum stakes because in order to do below minimum stakes bet Betting Assistant has to place 3 bets.
See the following video which explains how you submit a below minimum stake bet on Betfair:-

As you can see from the video if you wanted to place a 50p bet you still need to have at least £2.50 available balance.
I suspect you are working with a very small available balance which is why you are getting the exposure exceeded message.

Regards,
Mark
