Binance Scheduler Element

The Binance Scheduler ekement synchronizes subsequent elements with the time of the Binance server. Regardless of your local system time, the Binance Scheduler ensures that you get always the latest marked data.

Scenario:
,,Real" Binance time 15:52, time on your machine: 15:59. If you would have setup a standard scheduler to query marked data every full hour, you would query 53 minutes old data on 16:00. The latest marked data would be available on the Binance serve when on your local machine it is 16:07.

To prevent such a scenario, you should use the Binance Scheduler element to synchronize subsequent elements with the Binance time. You can also apply an offset (e.g. +10s) to ensure that the latest data is available on the server when you start your query.
