Behavior

The generator subscribes to real-time push data for the current instrument and updates the countdown every 500ms. The timer displays the remaining time in HH:MM:SS format.

When a new candle appears, the timer automatically repositions itself adjacent to it.

The generator includes a legend entry showing the current countdown value.
