I've read the manual but I'm still confused.
In my trigger, I have a constant which is defined as 0.1 * balance.
The manual says
"Constants are variables whose values can be defined upon loading a trigger file they are stored in. That is, a constant can be declared before any trigger starts working."
So I load the trigger and all is fine.
I then made a deposit to betfair, and my "constant" was immediately recalculated to reflect the new balance. The trigger was not even running.
So How do I set a truly global constant, i.e. work out 10% of my bank and have that figure available even when the bank changes during the day?
