  Capstone Project Issue| 3. Data Analytics and Reporting (Fail "tradeContext Has Correct Format")

  Posted by ziong on September 26, 2022 at 12:00 am

  Hi all,

  I fail in a test case on exercise 3.1 “tradeContext Has Correct Format”, test report as below:

  testSection[`exercise3]

   

  quizItem success description                        error 
  ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 
  exercise3.1 Pass "tradeContext Is Defined In Process" "" 
  exercise3.1 Fail "tradeContext Has Correct Format" "" 
  exercise3.3 Pass "badTrades Is Defined In Process" "" 
  exercise3.3 Fail "bad Trades Has Correct Format" "" 
  exercise3.4 Fail "abort" "abort in before block due to error "/developer-1.5.0-linux/workspace/__nouser__/funds_capstone/badTrades.csv. OS reports: No such file or directory""

   

  i cross-checked with the project description, seems everything looks good.

  (example from project description)

  date	option_id	trade_id	time	price	qty	side	edge	exch_id	broker_id	bid	ask
  2020.08.06	FB20200720C230	“258”	13:01:30.268	22.82637	99	S	-230.8243	4	705	44.55	45.9
  2020.08.06	KO20201120P55	“142”	10:52:10.106	55.65839	68	B	172.7843	3	703	77.74	78.74

   

  meta tradeContext (tradeContext’s schema)

   

  c        | t f a 
  ---------| ----- 
  date     | d 
  option_id| s 
  trade_id | C 
  time     | t 
  price    | f 
  qty      | j 
  side     | s 
  edge     | f 
  exch_id  | j 
  broker_id| j 
  bid      | f 
  ask      | f

   

  5#tradeContext (sample data)

   

  date       option_id    trade_id time       price   qty side edge exch_id broker_id bid ask

  I have no idea which columns go wrong, anyone can give me some hits?

  Thanks.

  Dear all,

  I fixed it.

  for those who encounter the same issue, there is the correct schema:

  meta tradeContext

   

  c        | t f a 
  ---------| ----- 
  date     | d 
  option_id| s   p 
  trade_id | C 
  time     | t 
  price    | f 
  qty      | j 
  side     | s 
  edge     | f 
  exch_id  | j 
  broker_id| j 
  bid      | f 
  ask      | f

   

  good luck
