Need to change a trigger

Hello guys and girls...

Need some help to change a trigger that bet before the race to bet in-play. 

"Backing on the selection with the greatest increase in matched volume%"

The trigger is this: https://marketfeeder.co.uk/learn/triggers/back-max-volume-increase/

I "only" want that this trigger start to check the variables only in-play and not 10 minutes before the off. And during the race, if the conditions are met the trigger fire the bet. You can keep all the same settings as it is.

I try by myself but it doesn´t work. Don´t see why... Can you give me a hand on this?

Hi
It is better to put a trigger request in to ask for the exact changes you want. But I will suggest a few things you can try:

• mins1 constant set to -0.16. this is 10 secs after the off
• mins2 constant. you need to decide how long to compare volume increase from remembering volume to placing a bet. for example if you want to wait 30 secs after volumes are remembered to find the max volume increase then mins2 constant should be -0.64
• the backing trigger sends a "back at SP" bet. this can only work before the off. so the trigger action needs to be changed to "back"
