Trade Multiple Systems in one IB account, any issues?

Hi all,

Just want to know your experiences on trading multiple systems on one IB account, especially the systems trade one instrument eg. E-mini. Whether this will cause any problems? I just worried about each system generated signals intervene with each other’s signals and positions. If I trade multiple ES systems in a single IB account, is this going to cause any issues?

I would be grateful if you can let me know your experiences. Thank you very much.
