Robot order of execution

Hi,

does anyone know the order of robot/instance execution?

For example, if the following robots are listed in cAlgo/cTrader in the following order:

Robot_1

- Instance_1 (e.g. EURUSD)

- Instance_2 (e.g. GBPUSD)

- Instance_3 (e.g. AUDUSD)

Robot_2

- Instance_1 (e.g. USDJPY)

- Instance_2 (e.g. GBPJPY)

- Instance_3 (e.g. CHFJPY)

Questions:

What is the order of execution, assuming that all the instances are all set to trade at the same time (e.g. Hourly)?

Do the robots run from top to bottom (Robot_1, EURUSD, GBPUSD, AUDUSD then Robot_2 ..., ..., ...) one after each other?

Do the robots start from top to bottom and run in parallel (asynchronous, finishing in and unknowable order)?

Do the robots start according to some other logic (e.g. alphabetically or even depending on the folder where they are saved)?

This would be useful to know so I can prioritize the execution of some robots over others.

Thanks for any advice,
