Cancel oco parent id I can see still stop loss leg status new

Getting Started with Alpaca

Hi Alpaca Team,

I’m using the Trade API in paper trading mode, and here’s the workflow I’ve implemented:

  1. I successfully submit a buy order using the Trade API.
  2. After the buy is filled, I submit an OCO sell order (limit + stop) using the same API.
  3. I’m able to update/replace the OCO order dynamically based on certain price conditions.
  4. When the condition is false, the program does not update the OCO order (as intended).

However, I’m facing an issue in the final step:

  • Every time the condition changes, I cancel the previous OCO order and submit a new one — this is working most of the time.
  • But occasionally, when I cancel the OCO order, only the limit order gets canceled, while the stop order remains active.

Could you please help me understand:

  • Why the stop order might not be canceled?
  • Is this a known issue in paper trading?
  • Is there a recommended way to ensure both legs of the OCO get canceled?

Thanks in advance!
