This theory sometimes invokes the use of "oscillators" such as Welles Wilder's RSI or Gerald Appel's MACD, both of which convey information about the momentum of the variable of interest. One influential contributor to this theory developed %b [percent-b] bands which, along with the %R [percent-r] indicator and parabolic SAR lines, are used as overlays in its practice. In this theory, upper and lower bounds of a certain variable are described as "resistance" and "support" levels. Unlike its counterpart, it does not involve assessing the cash flow involved with a security. Pioneered by John Bollinger and Charles Dow, it entails following the price movement and trends of a security to determine whether to enter a long or short position. For 10 points, identify this theory of finance contrasted with fundamental analysis.
