Alerting on Changes in the Best-Fitting Regression Model
Summary
This alert tool monitors an indicator that compares linear, quadratic, logarithmic, and exponential regressions, then selects the model that best fits the analyzed data. It notifies the trader when that selection changes, including when the fitted regression type switches from one form to another. The alert is intended to draw attention to possible changes in regression-based support or resistance and help traders react to potential breaks.
The document illustrates how a change appears in a graph and an alert panel, but gives no test results or detailed rules for interpreting a model switch as a trading signal. It cautions that using very short timeframes or monitoring many symbols can produce frequent alerts. The alerts therefore identify changes in model selection; they do not establish that a support or resistance break has occurred or indicate how to trade it.
Key ideas
- The indicator compares four regression forms and selects the best fit for the analyzed data.
- An alert is generated when the selected regression type changes.
- A change in the fitted model may draw attention to potential support or resistance breaks.
- Short timeframes and large watchlists can produce many alerts.
- The document provides no performance evidence or independent confirmation rules for the alerts.
