Technicals are price, volume, positioning, sentiment, etc., which are typically measured quantitatively or via a chart to assess momentum or mean reversion. I think that’s okay, and there’s some basis for that (momentum anomaly, cointegration between price and volume, the way large orders are distributed as a % of adv, option positioning pinning to round numbers, etc.).
What’s stupid is to stop your analysis there or to base a trade on a pattern you believe is forming. The “chartist” or “I only look at price + technical indicators” approach is dumb and I doubt you’ll find people who make excess returns from it. But I mean hey good for your broker lol.
