Numpty, sorry MarkV, trigger attached.
I stared at this for an hour last night but just couldn't figure how you changed the stake to an equal amount each bet.
Also, I would like to set up a secondary trigger (completely separate) that is similar to the original but looks at BSP between a certain range, say between 20 and 40. Then, if the in-play SP goes down by 50% a bet is placed. I'm not sure whether I will do this on cumulative percentage betting or fixed amount bets. However, once I see the rudiments of what you've done I'll be able to adapt it.
Once again, thank you for your help.
Kind regards
Rob
