You are showing your TWS settings in the .png image (I assume). I should know that as you are executing manually... Not sure where it is in TWS client. Seems logical it would be with Smart routing. Definitely a different setting box between API and TWS client... My evidence is way too little to draw conclusions, but across around 120 trades (120 before and 120 after) long & short, the results are nice. I think >100 smoothed out some big 'pothole' slippage hits, and the "price improvement" added a nice overall touch. But ask me after 1,000 trades :-0 I'm at 939.3 too. I attached image of the price improvement 'info' bubble for the check box. Found the setting in one of IB's demos or manuals. ![]() |
