At this point, it is a lost cause for us to recover the missing historical data for NASDAQ TotalView. We have tried. The best we can get to is about 11:45 AM and then we start running into problems. Update: We now understand why there was a problem at 11:45 AM, on Friday, June 12, 2026. This issue was encountered both in real-time and during historical data recovery. At that time there was either some faulty data or unexpected data from NASDAQ TotalView, which caused a high CPU usage condition that just simply went on endlessly. We do not know more than that. We did not record the raw data at that time to be able to debug it. We have never seen this before. Maybe we can get the data from the exchange. But that is not necessarily an easy process for multiple reasons. The NASDAQ TotalView TCP feed is simply unusable on days like today (June 12, 2026). And if anyone doubts what we say about NASDAQ TotalView needing to use multiple channels, for their data feed, this is not something which is debatable. The CME, has numerous channels for their data. The US equities data from UTP and CTA, use 6 and 12 channels respectively. And NASDAQ is trying to push, the entire US stock market and also, market depth data, through a single channel. It is way too much data. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.
