Obviously, this is not TA 101 day one. The forms are drawn by the price. Backward looking. The influences of buyers and sellers, large or small. The influence of company fundamentals, PRs, conference calls, general market conditions etc... TA doesn't ask why. I don't think size matters. It plots, it is interpretable. Trends are discernible. Interpretations are more risky at times than at other times. Sometimes it's as plain as day and wrong. You get the idea. Trends are suggestive. Trend breaks are too. Forms are tried and true observations having been made consistently over great long periods of time by skilled practitioners. If it dots, it plots. (I made that up.) Whether the future is indicated too is anybody's guess, which is all it is. Perhaps, an educated guess, lit by the lamp of the ages. Until the unfolding confirms or contradicts.
