I'm having trouble understanding the difference between static&dynamic data types.
By the looks of it (before reading that is), I'd assume static is essentially historical data, wherever stored; and dynamic is live data.

But as per documentation, live trading data is also considered a static type. Guess it all boils down to the different data types (on the language level)
they feed listeners with (array vs object), but I'm still unable to grasp the difference.
