  Introduction to PyKX section 3 Exercise 10

  Posted by ziong on September 27, 2024 at 4:11 pm

  Hi all,

  for the exercise 10:

  Return all close prices and volume from tab_BTC for the last date

  
  

  I wonder that the suggested solution may be incorrect.

  tab_BTC.get(['volume', 'close', 'date'], tab_BTC['date'] == kx.q.max(tab_BTC))

  it returns all rows without filtering the date with last date.

  see attached.

  
  

  seems that this should work like this (returns 180 row):

  tab_BTC[tab_BTC['date'] == kx.q.max(tab_BTC['date']), ['volume', 'close']]
