auto trade thru IB performance vs manual trade

Hi,

Any one using auto trade thru IB successfully for last 5 months ?

How about the performance, it looks better than manual trade?

Whether, only market open order is placed? or
any new strategy found to place limit order with 100% execution in IB-Auto trade to match with R2G or Personnel trading systems recommendations.

This is my first year anniversary with portfolio123.com,
Would like to know how others are doing with auto trading + IB and portfolio123 tools.

Still learning from these forum when find time after my full-time job.

Thank you
Kumar

If I remember correctly trades placed through an API cost 50% more than through the IB tws

P123 TRADE sends order via the FIX protocol, not their API. I was no aware of their API price difference, but FIX is an industry standard and probably has the same commissions as TWS.
