Description

We found 23 issues in our data vendor's map files; these are extremely rare cases (23 out of ~30000) and refers mostly to low volume securities.

The issues are related to old securities map files having overlapping ticker usage.

The affected tickers are:

  1. VXZ
  2. TME
  3. OILU
  4. OIL
  5. GDYN
  6. ASX
  7. WES
  8. STRZA
  9. JJU
  10. JJE
  11. JJC
  12. ILTB
  13. TCF

  18. SWI
  19. HCACU
  20. NIO
  21. DHCNL
  22. PTMN
  23. ALQA

We already reported them, and we're working in an in-home solution to avoid this kind of issue in the future.
