Volume of Orders on CMC markets

Every order that goes through the CMC Markets system is given a sequential number. I found the numbers interesting because given that it was 11pm at night, and the Aussie Markets were closed (while the US markets were just opening), the difference of both my orders to enter and exit the trade was 1676. That means 1676 transactions in the CMC markets platform was performed in the 30 minutes I was in the market. I wonder how many orders CMC markets process every day?
