Euro Strength Index Pro is a custom Mt4 indicator that gauges the Euro’s relative strength across seven major Forex pairs (EURUSD, EURGBP, EURJPY, EURCHF, EURAUD, EURCAD, EURNZD) with equal weighting.
It computes the percentage change over a configurable LookbackPeriod (default 14 bars) for each pair, averages these moves into a single raw ESI value, and then applies two successive EMAs: one to smooth the raw index over SmoothPeriod (default 5) and another to generate a SignalLine over SignalPeriod (default 5).
Positive and negative values are plotted as a green/orangered histogram, while the smoothed ESI and its signal line (gold and blue) are drawn as optional lines in a separate window.
