  fundamentals capstone 3.4, 4.6

  Posted by Kal8na on April 12, 2024 at 1:16 pm

  In exercise 3.4 I’m getting an error when I’m saving the badTrades csv.

  answer:

  save `:getenv[`AX_WORKSPACE],"/badTrades.csv"

  error: getenv/AX_WORKSPACE. OS reports: No such file or directory

   

  In Exercise 4.6 I’m having a type error. I just wanted to check my below code is right or I have an misunderstanding of the question.

  answer:

  timeSeries:`edge`Qty`numTrds!{(exec x from edge15)}`$/:{exec i from edge15} each `edge`Qty`numTrds;

  error: type: Mismatched types

  Hi @kal8na ,

  There is a typo in your line

  save `:getenv[`AX_WORKSPACE],"/badTrades.csv"

  You’re missing the $ operator.

  I can help clarify what’s being asked in 4.6.

  You will need to use the xbar function to create the edge15 table, and then use exec to extract the fields you need for the timeseries dictionary. It should be a simple

  timeseries: exec ... from edge15

  Hope this helps!
