The True Strength Index (TSI) is a technical indicator that measures the strength and momentum of an asset's price movements. It was developed by William Blau and was first introduced in 1991. The TSI value oscillates around a zero line, with positive values indicating bullish momentum and negative values indicating bearish momentum. The True Strength Index often identifies potential trend reversals and confirms existing trends. When the TSI crosses above the zero line, it may signal a potential buy signal, while crosses below the zero line may indicate a possible sell signal. Traders may also look for divergences between the TSI and the asset price as potential buy or sell signals.
