  Capstone 2.3

  Posted by bldulam1 on April 24, 2023 at 12:00 am

  I am having trouble with Exercise 2.3 in the capstone project. I tried making both trade_id and exch_message as strings, but my solution is still incorrect.

   

  here is the meta messages:

  c | t f a

  ————| —–
  trade_id | C
  exch_message| C
  broker_id | j

   

  This is my solution:
  messages: update trade_id: string trade_id, exch_message, broker_id: extractBrokerId each exch_message from messages

  extractBrokerId: {[exchMsg]
  temp: “-” vs exchMsg;
  msg: temp[0];
  res: temp[2];
  if[msg~”ISE”; res:temp[1]];
  “J”$res
  }

  Hi  – you are very close! I had a go running your solution and see a different meta than what you have shared.

   

  It’s the first column trade_id where the issue is – you should not need to add string in front of it.

   

  messages: update trade_id: trade_id, exch_message, broker_id: extractBrokerId each exch_message from messages
