Stop behaviour question

[adamplatt]

Hi,

I'm just playing around with some automated scripts and have a question about the stop function. I was playing around with a variation of the front runner script and made it do a back bet with offset, greening and stop just before the off. The offset and greening work as I expected but I'm struggling with the stop.

In an example it placed at £2 @ 3.8 (matched) and placed a £2.60 lay @ 2.92 (unmatched) before the off and set it to "keep". In play the odds drifted and triggered the stop which then placed a £2.60 @ 5.6 giving a 11.96 liability on that lay. In this instance the horse fought back and won leaving me down more than the initial £2 stake. I wasn't expecting a stop loss to trigger a potential bigger loss. I'm obviously missing something about the way it works?

I would guess that you were probably expecting the size of the stop bet to change according to the stop position in the same way that a green up bet would.

However, I believe the software always sets the size of the stop bet equal to the offset bet.

The user guide says...

"Offset bet with greening and Stop - As 'Offset bet and stop' but Bet Angel adjusts the stake of the offset bet so that the profit from the trade is spread across all selections in the market. Note: the reduction of the stake of the offset bet will result in the stake used for the stop loss being reduced also."

It may be better for you to use a separate rule to green up if your loss exceeds a pre-defined amount.
