I have been trying to place trailing stop loss orders but I cant seem to do it. I can place other orders just fine, buy sell, stop loss.

Here is my code

api.submit\_order(  
symbol=‘AAPL’,  
qty=1,  
side=‘sell’,  
type=‘trailing\_stop’,  
trail\_percent=0.05,  
time\_in\_force=‘gtc’,  
)

and here is my error,

* * *

TypeError Traceback (most recent call last)  
 in   
----\> 1 api.submit\_order(  
2 symbol=‘AAPL’,  
3 qty=1,  
4 side=‘sell’,  
5 type=‘trailing\_stop’,

TypeError: submit\_order() got an unexpected keyword argument ‘trail\_percent’

Whats wrong with my code? It’s taking from the alpaca api docs.

trail percent needs to be string
