Chork's Puzzle 26

Difficulty Rating: 3

Chork had been on a long space trip (which explains the lack of puzzles during this period) and got to see many new and interesting things. For instance, on this planet, he met an alien which was drawing some weird symbols according to a strange pattern. The following are the first 5 members of the sequence.

He notices 4 other different symbols which are supposedly the next 4 members of the above sequence (but not necessarily in that order). Note that the symbols are labelled A, B, C, D ONLY for easy reference to the particular symbol.

A: B: C: D:

Can you arrange the four symbols in the correct order so that they continue the sequence of 5 symbols above?

What is the order?
