Hi , 
I got paused in the exercise 4.6 which has a query
4.6 Extract the 15 minute aggregate series for each of edge, qty and numTrds usingedge15 (or otherwise) as a dictionary and store this in a variable timeSeries.

can anyone explain how to approach this and what is required as a final output from this exercise?

Here is sample output for what the timeSeries variable should contain - expected output is a dictionary.
