Post From: Attached order (take-profit) cancel/replace rejected during partial parent fill

This issue is strictly a Rithmic specific issue. We cannot help with this.

If you want to use Rithmic, then we cannot help. We just simply cannot help with this at all. These are not Sierra Chart issues at all.


1. Is there any Sierra Chart-side setting that would prevent the Trade Service Log popup from opening automatically when this rejection occurs, without disabling all error notifications?
Refer to:

General Settings Window: Never Automatically Open Message Log or Trade Service Log (Global Settings >> General Settings >> Log >> Log)


2. Would disabling 'Adjust Attached Orders to Maintain Same Offset on Parent Fill' help avoid the rejection, and what would be the exact side effect on stop/target quantity management?
No. The order modification would occur anyway because the quantity has to be increased.


3. Is this rejection specific to Rithmic's handling of cancel/replace during fast fills, and is there any known workaround short of switching to Teton?
Yes it is a Rithmic specific issue.


Would server-side bracket orders (Use Server Side Bracket Orders) change this behavior for Rithmic, or is Rithmic's OCO/bracket handling client-side here?
Is there anything specific about Rithmic's cancel/replace handling during fills that makes this worse, versus other trading services?
Rithmic does not support server-side bracket orders. You will not have this problem when using Teton order routing or the Trading Evaluator service from Sierra Chart.
