Custom watermark

The CustomWatermark module controls the large background watermark text — shown over the chart canvas — with full control over visibility modes, colors, and content overrides.

Overview

Edit custom-watermark.js to call window.ChartingAPI.setWatermark(). By default the watermark auto-displays the active symbol, description, and resolution.

Settings API

window.ChartingAPI.setWatermark({
  show: true,
  watermarkMode: 'always', // 'always' | 'replay' | 'none'
  showWatermarkTicker: true,
  showWatermarkDescription: true,
  showWatermarkInterval: true,
  showWatermarkReplay: true,
  symbol: 'BTC', // Force a specific symbol text
  description: 'Bitcoin', // Force a specific description
  interval: '30m', // Force a specific interval text
  defaultSymbol: 'BTCUSD', // Fallback when no chart loaded
  defaultDescription: 'Bitcoin / U.S. Dollar',
  defaultInterval: '30m'
});
