Synthwave Indicator - FairyTrash/Legit?

So this is me trying to use the Synthwave indicator tool. In all fairness, to me, the logic behiond the way I've used it here just somehow makes absolute sense but then I step away for a second and when I come back to take another look at it, I think - what was I thinking and how did I get to this?

I don't know, what do you think? Im obviously using this wrong but if anyone knows how to use it better, please show us?
