Limit Sell Order Pre market

How can I place a limit sell order in the market that can then be executed on the upcoming pre-market?

Hello, Jimmyrakete,

Please refer to the rules of your exchange. If it accepts orders before the session starts, you can place an order in accordance with your script logic (in auto trading) or manually at the desired time. But it is not possible to place orders If the exchange doesn’t accept them before opening of the session.

In order to receive data during pre-market/post-market hours you can select 24/7 in Format Instrument -> Settings -> Sessions, or create and use your own custom session template:

E.g. CME you can manually place premarket orders everyday from 22:45gmt(bst) / from 22:00gmt Sundays.

If automated you will need to look at IOG.
