NxtChartPage.scalper constructor

const NxtChartPage.scalper({
  1. required ChartInterface dataProvider,
  2. String? initialOptType,
  3. Key? key,
})

A landscape, two-panel scalper layout: dataProvider's symbol on the left, its ATM CE/PE strikes on the right (see MarketDataInterface.atmSymbols).

initialOptType pre-selects which right-panel leg ("CE" or "PE") is shown first; pass null to use the default.

Implementation

const NxtChartPage.scalper({
  required this.dataProvider,
  this.initialOptType,
  super.key,
}) : _scalper = true;
