sp back amount

Hi, I've been trying out a trigger which involved small back bets at sp. I couldn't get it to fire. Is there a minimum bet below which I can't place an sp back bet, even if the allow small bets box is ticked in settings ?

Hi
From BetFair:
"What is the minimum stake for an SP bet?
The minimum stake for a back bet at BSP is £2 or the local currency equivalent as per normal. The minimum liability is £10 or the local currency equivalent."

Allow small bets is accomplished using three bets. This can be done at a specific price, but because the SP is not known until the bet is matched, small bets procedure will not work. Effectively if the SP bet is below the stated minimum it will be rejected by BetFair.

that explains a lot, many thanks

If you set it to place a 'normal' small bet at 1000 with the persistence set to take BFSP at in play you should get the desired effect - its also a way of making BFSP bets effectively cancellable.
