Change QFL Percentage by available Balance
You can use a custom condition to find out how much percentage of your total Balance is currently available. And depend how much is available, you could update the start conditions.
I am actually not sure if that rule makes sense
but you get the idea of a custom expression.
This one will be true, if there is more than 75% of the total balance available in BUSD.
You could then have different levels/percentages to switch between conservative or more aggressive start signals.
