Randomly choose another markets/timeframe

idea from forum by mabi:

multitimeframe settings can create endless of combinations . You can generate on time frame combinations and instrument combinations. It would be good to be able to randomise mulitimeframe settings aswell doing it manually and go thru possible combinations one by one

Options could look like.

1. Select  x additional charts to look at

2. Additional instrument should have a  Randomize option to be selected from a group of instruments.

3 Additional Charts time frame should have a Randomize option as well.
