Measuring latency of opening a position in CTrader through FIX API

Hi,

I am trying to find out how much time it takes for an order request sent through FIX API to open a position.

In other words, what I would like to know is :

How do I know at what time CTrader platform received my order? and

How much time it took to fill the order?

I want to measure this because my client is interested in knowing the performnce of FIX application we are developing.

Any help in this regards will be appreciated.

Regards,

Pavan
