When is a constant not constant?

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?

hi
with constants, they must have fixed amounts/letters, not formula's.
if you want to set the day's amount, then use a trigger to set the amount (trigger set to one time only) or add an action to a trigger that is set to one time only.
so Add trigger
set user variable
name (name of the variable)
value balance*0.1
no condidtions
selection favourite (only used for activating the trigger)
markets all markets
market status all markets
Execute one time only

this will set the variable to 10% of your balance and will only change if you reload the triggers

Sorted.

Many thanks for the great support, really enjoying getting back into programming with MFP.

Next issue - how can I reset total_won (or set it manually to zero) so that I can leave the trigger running from day to day?

hi
the only way to reset total_won is to use a new trigger to reset win/lose history.
so new trigger
action reset win/lose history
conditions
and selections trigger expression total_won is greater than (your set profit)
selection favourite (only used for activating the trigger)
markets all markets
market status all markets
Execute once per market
