Some financial quants and traders use Python/Numpy or Matlab, which are both interpreted languages with array operations. Is the main advantage of APL-derived languages such as kdb or q speed or more concise code? ETA: I found a 2019 article "A comparison of Python and q for data problem solving" https://kx.com/blog/a-comparison-of-python-and-q-for-data-problem-solving/ https://kx.com/blog/a-comparison-of-python-and-q-for-data-pr... that compares Python/Numpy and q on analyzing tick data.
