Re: Fundamentals Capstone 2.2

Hi ,

I think one thing that could be helpful is using conditional evaluation Cond | Reference | kdb+ and q documentation – Kdb+ and q documentation (kx.com)

So you’ve got:

 

extractBrokerId: {[exchangeMessage] parts: "-" vs exchangeMessage;

 

Which is correct.

If we take a look at our messages table we can see that if the exchange message begins with CME – the brokerId is going to be at the end.

If it begins with ISE – the brokerId is going to be in the middle.

So using the conditional, we can basically say if the exchange message is like “CME*” then use the last part else use the middle part.

Let me know if this helps,

Megan
