I want to create a condition based on historic relative odds. I need to be able to back or lay a selection providing it hasn't traded below or above a certain price at all or throughout a certain time before placing a bet.
Eg
-Place back bet at 6 providing it has never traded above 10
-Place back bet at 6 providing it hasn't traded above 10 in the last 20min (not just at a point 20min ago)
How can I achieve a condition like this? I might not be thinking outside the box here
