chart.isLast#

True on the last bar of the current call (i === N - 1).

SYNTAX#

ctx.isLast: boolean

RETURNS#

boolean — true on the rightmost bar of the call.

REMARKS#

Common pattern: gate entity.* emissions to ctx.isLast so persistent overlays (support lines, target labels) only render after the warmup pass settles.

EXAMPLE#

function onBar(i, ctx) {
  if (!ctx.isLast) return;
  // Draw a target line only on the latest bar.
  entity.line({
    key: 'target', x1: candles[0].time, y1: 50000,
    x2: candles[i].time, y2: 50000, color: '#26a69a'
  });
}
