On chain analysis hasn't been any more (or less) useful than technical analysis (for me). Mechanically different but both capturing the same thing: human behaviour and market psychology. I think OCA is less useful as a timing tool, and don't look for absolute confluence between OCA and TA. Both methods are noisy, so the risk is doubling the noise and confirming your bias through finding even more metrics to agree with. In addition, neither exist in a vacuum, so if you're looking for confluence, both are subservient to macro.
