ML Lorentzian Classification FREE is a machine learning-based technical indicator designed for the EURUSD currency pair on the M1 (one-minute) timeframe, operating in 60-minute sessions. It implements an approximate k-nearest-neighbours classifier using Lorentzian distance to reduce the impact of outliers and volatility shocks compared to traditional Euclidean distance. The model uses eight neighbors across five normalized feature dimensions: RSI, WaveTrend, CCI, and ADX.

Key features include a Nadaraya-Watson kernel regression line displayed in bullish and bearish colors, default active volatility and regime filters, and BUY/SELL arrows positioned according to ATR for proper scaling. The indicator provides sound and popup alerts on new signals at bar close, bar coloring by prediction strength with confidence gradients, and a collapsible on-chart panel showing direction, prediction value, confidence, kernel state, filter status, and live trade statistics.

Users can customize only the buy and sell arrow colors; all other model, filter, and kernel settings are fixed. The free version is limited to EURUSD M1 and requires restarting the indicator to begin new sessions. It does not support parameter changes, multi-symbol use, or email alerts. This version serves as a trial with the same core engine as the PRO version, which offers extended symbol and timeframe support, configurable parameters, additional filters, exit markers, and alert options.
