Hi There,

When I am using extended_hours to true in python, I am seeing below error.

can you please show what is wrong here?

temp_buy_order_outcome = api.submit_order(
symbol=‘MSFT’,
qty=1,
side=‘buy’,
type=‘limit’,
time_in_force=‘day’,
extended_hours=‘true’,
limit_price=205.5)

@Nick_Peter, not sure if you’ve overcome this issue indicated above, but can you try using a boolean (True) – not a string?

Thanks a lot for your reply. Your suggestion helped me.

Thanks again.

Best regards

what boolean mean?
is the command below correct?
“extended_hours”: true,

Its binary true vs false. This is no a string. Try true, True, TRUE without quotation. Its up to your platform.
