ARIMA_SAX_Hybrid_Forecaster

This repository is a research framework for testing ARIMA and SAX hybrid forecasting. It does not claim profitable trading performance and must not be interpreted as a validated trading strategy unless explicitly demonstrated by reproducible out-of-sample evidence.

Purpose

This is a research project first, not a trading-product project. It builds a reproducible research harness to answer one central scientific question:

Does a hybrid ARIMA + SAX forecasting architecture provide statistically and economically meaningful incremental predictive information compared with appropriate baselines and with each component individually?

The two conceptual references are:

Method	Reference
ARIMA	https://www.mql5.com/en/articles/18247
SAX	https://www.mql5.com/en/code/75543

These are methodology and implementation references only. They are not evidence that either method (or their combination) has trading edge.

Research posture

• No assumption that either model has predictive edge.
• No assumption that combining two models improves performance.
• No live trading / execution in this harness.
• No lookahead is permitted. A failing no-lookahead test is a hard stop.
• No Edge and insufficient analog conditions are legitimate outputs, not implementation failures.
