I've discussed this with developer support recently but I thought a formal request in the forum may help things along.

Please send us trade Corrections & Cancellations. Without them any data grouped by tick or volume following an extra/incorrect trade is garbage or even dangerous. Even the derivative data calculated by iqconnect.exe would be incorrect without a fresh call.

My understanding is that the current workaround is monitoring the "Total Volume" for reductions and then calling HTT comparing some time span of trades to the historical lookup for the error...

Thanks,

William

William,

Thanks for following up with this post. We did receive your request and have it added to our roadmap for IQFeed. I don't have a timeline for if/when it may become available but we do appreciate you taking the time to provide feedback.

I also wanted to note that we currently have full correction/cancellation information being transmitted as part of our NxCore data service. You can take a look at the documentation for NxCore at www.nanex.net.
