Navigating Shifting Markets: A Causal Approach to Smarter Trading
![A normalization process-applied to financial indicators including Money Flow Index, Relative Strength Index, Bollinger Bands percentage, and Moving Average Convergence Divergence for both EURUSDT and BTCUSDT-centers the data by subtracting a 5000-minute rolling median [latex]I~^{(k)}\_{t}=I^{(k)}\_{t}-m^{(k)}\_{t}[/latex], then scales it using the rolling Median Absolute Deviation [latex]s^{(k)}\_{t}[/latex] to produce a dimensionless, comparable metric [latex]Z^{(k)}\_{t}=\tilde{I}^{(k)}\_{t}/s^{(k)}\_{t}[/latex] that facilitates direct cross-indicator analysis and aggregation.](https://arxiv.org/html/2603.13638v1/x1.png)
