Nine indicators equals zero indicators
If you need six confirmations before entering, you don't have six edges. You have one idea and five ways to arrive late.
Most indicator stacks are the same input transformed six times. They agree because they're all reading the same price series, so "confluence" is mostly autocorrelation wearing a costume.
I'm not saying use none. I'm saying be able to state, in one sentence, what each one contributes that the others don't. If you can't do that for all six, you have fewer than six.
