Post From: Charts lagging on extreme active periods

On Monday my charts were lagging by about 30 seconds. As a Transact client I am aware of the changes that you made on the data feed some months ago.(Which is much better now) If I assume correctly, the chart feed is now a LIVE trading feed with Sierra Charts controlling 'LIVE' or 'SIMULATED' modes. The Transact trading DOM which was also open on the same computer with the same internet connection (25 mps download/5 mbs upload) did not exhibit this lag. I am NOT a programmer and please do not take this as criticism but may I suggest that if the data servers were NOT overloaded and lagging that sampling the incoming RAW data at several times per second and processing and charting the resultant sampled rate could result in non lagging charts during extreme active periods. I know that this is not true unfiltered data and would not satisfy some, but possibly a practical solution. Even dual sampling, ie. sample the raw data and then sample the result. I repeat, this is NOT criticism in any way but a genuine desire to suggest an idea that your programming team could look at. Regards Tech Trader |
