Stochastic Math

• %K Line: ((Current Close - Lowest Low) / (Highest High - Lowest Low)) * 100 calculated over the period (typically 14).
• %D Line: 3-period simple moving average of the %K line.

API Registration

Register the Stochastic Oscillator using the Charting API:

window.ChartingAPI.registerIndicator('stoch', {
  name: 'Stochastic Oscillator',
  type: 'pane',
  levels: [20, 80],
  params: { kPeriod: 14, dPeriod: 3 },
  defaultColor: '#ff9800',
  calculate: function(bars, params) {
    // Returns { kValues, dValues }
  },
  render: function(ctx, chart, values, bounds, color) {
    // Render %K (orange) and %D (blue) line plots...
  }
});
