Order cancellation not performed

(paper trading)

When I create an order and then quickly cancel it, the cancellation will not actually happen in many instances.

Here is a trace:

HTTP request: DELETE to https://paper-api.alpaca.markets/v1/orders/7dcb16ae2f86476887cc69d1838d0e85

Basically I create an order, retrieve it (optional, it's just for testing) and then cancel it. Everything seems to be going fine, except that the order is still being listed on the UI or when I list all orders programmatically.

Now, if I insert a delay of a couple of seconds between the POST/GET and the DELETE (two seconds seems to be the minimum), everything works just fine (same trace, it's just that the DELETE now actually deleted the order).

Hi @d-e-s-o - thanks for the report. We're currently testing a fix for this issue with our paper trading simulator, and we hope to release it soon.

We've released an update to our simulator, and issues like this should no longer be happening. Please file another issue if you see any more unexpected errors like this.

Awesome! I'll try it out tomorrow. Thanks for the quick turn around!
