Vector Subtraction (SUB)

SUB performs element-wise subtraction of two data series: Output[i] = Input1[i] - Input2[i]. This mathematical utility is fundamental for calculating spreads, differences, and oscillators. Most oscillators (like MACD) are essentially subtraction operations. SUB enables explicit difference calculations between any two series.

Developers use SUB for creating spread indicators, calculating price differences between assets, or building custom oscillators. Essential for pairs trading (price1 - price2), relative performance tracking, and any strategy based on divergences or differences. SUB is the foundation of most momentum and oscillator indicators.
