What extensions for preferred stocks do you use?
For preferred stocks we use dot delimiter. For example, Berkshire Hathaway Inc.(BRKB) has two type of stocks A class and B class. In our system it will be BRKB.A and BRKB.B. This format is also adopted by the largest stock exchange in the world which is the NYSE.
Why do extensions for preferred stocks differ across exchanges?
Since there is no unique international standard, every exchange is able to use their own notations. Such notations can be:
Why the closing 1 minute price might differ to the 1 day closing price?
To update stock prices realtime, tick prices have to be used in order to ensure highest data quality. Some stocks with really big trading volumes can have different daily closing prices due to stock exchanges ineffectivness when they calculate the official stock closing for the day.
