# StockCharts Theoretical Indices

## Definition <a href="#definition" id="definition"></a>

StockCharts publishes a series of “theoretical” indices that show an idealized pattern or trading sequence. For example, $THEW charts an ideal Elliott Wave sequence with three waves up and two down. $THHS charts a classic head-and-shoulders pattern on the chart. These indices can be used to understand how indicators react under these theoretical conditions.
