Hi Yoshi, nice Trailing Stop is a nice feature. I tried it today in Paper Trading with a short. It worked but not quite as I expected: here is what I got:

Trailing Stop Buy with trail price @ $4.25 and HWM $107.30
created at 09/24/2020 09:55 AM
filled ($109.84 each) @ 09/24/2020 01:32 PM

I would have expected it to get filled above $111.55. It was AAPL (it that helps). Any explanation?

@yoshi Thank you for implementing this! When I use execute the following code:

live_api.submit_order(symbol="SWKS", qty=1, side="sell", type="trailing_stop", time_in_force="gtc", trail_price="5.0")

I get the following error:

TypeError: submit_order() got an unexpected keyword argument ‘trail_price’

Any explanation? Thanks

I’m having trouble with this feature.

If I follow the example in the documentation https://alpaca.markets/docs/trading-on-alpaca/orders/ but via Python

api.submit_order(symbol='AMZN', qty=1, side="sell", type="trailing_stop", time_in_force="day", trail_percent=1)

I get the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: submit_order() got an unexpected keyword argument 'trail_percent'

I’ve messed around with switching the side and from trail_percent to trail_price and get the same error. If I remove the trail_percent or trail_price from the call it then tells me it’s required.

I’m sure this is user error, but any guidance would be helpful.

Thanks

I just had to update my alpaca. I used:

pip install -U alpaca-trade-api

Good luck everyone!

Fixed for me as well!
