Technical analysis guy over here! It’s just probabilities. Some TA folks go nuts with indicators. Not too different from the Bitcoin fundamental dudes looking at hash rates and other on-chain metrics.
It definitely works for me, even simple things like Fibonacci levels, support and resistance, volume profiles, gaps, and RSI/macd are more likely than not to provide good valuable insight. Just S/R can be enough honestly.
Liquidation heatmaps are nice too!
