True Strength Index Strategy: Momentum Trading with TSI
The True Strength Index (TSI) is a momentum oscillator that measures price change momentum through double exponential smoothing, producing a line that oscillates between roughly +100 and -100. It's designed to separate genuine trend moves from short-term noise. I've been running this on TSLA daily charts since November 2024, and the zero-line cross caught the December rally a full two sessions before most lagging indicators confirmed it. For traders who combine this with the Average Directional Index (ADX) for trend strength analysis, you get a dual read on both momentum and trend conviction — and I find the combo cuts false signals by a noticeable margin.
