Why did my Tradier paper order fill on a weekend?

Tradier's paper sandbox can mark a resting order as filled on a weekend, at a price no real market printed. Tradier's API reports it as a fill, so Nyria records it and the bot moves on to its exit. Judge Tradier paper results on regular weekday sessions only.

Official documentation

Check a weekend paper fill on Tradier

  1. 1

    Check the day

    Note whether the fill landed on a weekend or after the close.

  2. 2

    Check the account type

    Only a Tradier paper (sandbox) account does this.

  3. 3

    Open the bot logs

    Expand the row to see the Tradier order id and fill status.

  4. 4

    Set the fill aside

    Do not judge the strategy on a weekend sandbox fill.

  5. 5

    Test on a weekday

    Re-run the check during the regular session, Monday to Friday.

What happens on the sandbox

  • A limit order placed late on Friday can show as filled on Saturday.
  • The price was never printed by a real market.
  • Tradier's API reports the order as filled.

What Nyria does with it

  • Nyria records the fill as Tradier reports it.
  • The bot then moves on to the exit step.
  • Nyria does not second-guess a fill the broker reports.

Does a live account do this

  • No. Only the sandbox shows this behavior.
  • A live Tradier account fills against the real market.
  • If you see it on a live account, note the Tradier order id and contact support.

How to judge paper results

  • Use regular trading hours, Monday through Friday.
  • Ignore weekend sandbox activity.
  • Compare the Nyria log row with the Tradier dashboard order id.
