IYO, what risk per trade, as a percentage of Account Balance, indicates that a signal provider has confidence in his/her signal ? - page 3

[Ubzen]

If all signals provider used full kelly or optimal-f or some other criterion based on the system's edge then their percentage sizes would reflect confidence in their system. But because I don't believe most providers use proper money management, therefore, I don't believe there's any correlation to be drawn between percentage risks and providers confidence.
