The HighLowMarkers generator displays horizontal marker lines for the high, low, and/or close values of a configurable lookback period. This allows traders to quickly see key price levels from recent history.
Use a Controller object to add the generator to a chart:
const highLowMarkers = controller.addGenerator('HighLowMarkers');
