I changed it to :
order = self.create_order(
self.symbol,
quantity,
"sell",
take_profit_price=last_price*.8,
stop_loss_price=last_price*1.05
)

from advice from Strategy class:
>>> # For a bracket order
>>> order = self.create_order(
>>> "SPY",
>>> 100,
>>> "sell",
>>> take_profit_price=limit,
>>> stop_loss_price=stop_loss,
>>> stop_loss_limit_price=stop_loss_limit,
>>> )

[cannuri]

so you don't define the type at all? How would it know it is a bracket order then?

[aceacs123]

I was hoping to make limit buy/sells with this code. so I need to better understand this part.

[yannie95]

Anyone who has the solution for the type argument error?

[OWEBS]

Not sure if this answers your question, but I had this error and I simply got rid of the type="bracket" since the error states it is not expecting it. This allowed has allowed my program to finish. Hope this helps.

order = self.create_order(
self.symbol,
quantity,
"sell",
#type="bracket",
take_profit_price=last_price*.8,
stop_loss_price=last_price*1.05
)

[yannie95]

Thanks for your answer! But how can I submit a limit order now?

[M-Brock]

Lumibot changed the parameters apparently, type is not valid anymore. How to make a limit order or other types of orders (like a bracket order) can be found on their documentation https://lumibot.lumiwealth.com/entities.order.html#advanced-order-types.
