Alpaca is canceling my orders

Hi
I submit order with alpaca python sdk, get client_order_id, but then on get_position(symbol), position is not found, and in the dashboard it seems stuck, with status of NEW
it only happens with order of type=‘trailing_stop’

Any reason why?

Trailing stop orders are supposed to fill when the price hit the stop price. “Trailing” nature is that this stop price moves along with the market price, but other than that trailing stop orders are basically stop orders. Are you seeing order don’t fill even after the price hit the stop price of the order?
