Struggling to Define My 'Edge' - How Do You Guys Pinpoint Yours?

Hey everyone, fairly new here, still trying to get my feet under me. I've been doing a lot of reading and practicing, and one concept that keeps coming up is defining your 'edge'. I understand it's what gives you a statistical advantage over time, whether it's a specific setup, a unique market interpretation, or even just superior risk management.

The issue I'm having is actually putting a finger on what my edge is, or could be. I feel like I'm trying a bit of everything – some basic support/resistance, a few simple indicator-based strategies – but nothing feels consistent enough to call it 'my edge'. It just feels like a collection of ideas rather than a cohesive strategy. For those of you who have been at this for a while, how did you eventually identify or develop your specific edge? Was it through extensive backtesting, just screen time, or something else entirely? Any advice on how to approach this would be super helpful.
