True Strength Index Ruby API Documentation

The True Strength Index (TSI) is a momentum oscillator used to identify building trends and trend reversals, typically by signalling overbought and oversold conditions. TSI fluctuates between positive and negative values, and traders typically combine its signal with other momentum oscillators to increase its strength. When TSI crosses the signal line into positive territory it is presumed to be an entrance opportunity and vice versa when the TSI crosses into negative territory.
