Hi,

My system: MacOS, Python via Wine

(A) I have my real time feed connection and am looking for the best practice way to filter by 5 minute bars for symbols. I tried to add 'Most Recent Trade Time' to a select update fields message but I'm getting an error response:
- E,Most Recent Trade Time is not a valid fieldset field.,

(B) On top of that, I now get connection refused and can no longer access via port 5009.

Please advise on both.

Thank you,
Matt

Hello,

A, is likely due to not setting your protocol. Make sure that for each socket that you create you are setting your protocol to 5.2. and then the documentation will match and make more sense.

B, this is a guess, but IQFeed will close after 5 seconds if no client is connected, so you will need to restart the app when this event occurs.
