Because of this, series may be drawn with unnecessary gaps where missing points should have been. To remove these gaps, set the ignoreEmptyPoints property to true.

• If a series must have a unique argument field, specify the same property, but do so in the series object within the series array.

Binance offers a WebSocket API to get live candlestick updates and I would like to build my own live Bitcoin price ticker with it in the future.
