[NOTE]
====
_remainingTimestamp_ is just an indication and _volume_ can change even after _remainingTimestamp_ has reached _0_.
This is because some exchanges will only update kline _K1_ once the first trade for kline _K2_ has occurred.
_closed_ will be _true_ only once the kline has been finalized.
