Hello, I use SCv1172. I have a chartbook with 3 charts and two are overlayed on the last one wich is very loaded in computed studies and alerts. I use Range Barchart that means during High volatility , number of bars could be numerous in a short lap time. My problem is sometimes I need to live change (6-10 times a day) some studies of the third Chart ; and It need usually 15 minutes to update all the chartbook because of the computation. In case of high volatility time, after the update is completed...I Have frequently the last 10 minutes of Bars missing !! and If I reload all the datas without changing any studies...the same. Is it possible to check what is the problem. Is the stack, the buffer inoperative ? Before this problem, I used the SCv1092 a very long time because I didn't have this problem that appeared later in the newest version. Now I'm very bothered because with datas missing in my chart ; calculation of my alerts are not accurate and sometimes false. Thanks for your great help |

Sierra Chart is not the provider of the real-time data feed in this case. The underlying problem is that you have some configuration which is taking a long time to perform calculations for. We have no idea exactly what that is. We recommend referring to help topic 30 here: http://www.sierrachart.com/index.php?page=doc/helpdetails30.html If there is missing data in the chart after the calculations, follow the instructions and help topic 7.1: Http://www.sierrachart.com/index.php?page=doc/helpdetails7.html When Sierra Chart has a direct connection to a data feed, which it does not in this case, even if the user interface becomes frozen for an extended time and the data feed is lost, when it is recovered, historical data will automatically be downloaded. So there should never be any missing data. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Hello Support, To check if I have the problem with my former v1091; I would like to open a SCv1172 ChartBook on SCv1091 ; I get the message "Unable to read newer Chartbook file format" !! I thought it was now possible to have the compatibility in the two ways ? Thanks for your help |

Chartbooks saved in a newer version can be used in older versions, but apparently 1091 has a check preventing the newer Chartbooks from being used. This problem has been fixed in newer versions.

Hello Support, To check the problem...I installed SC_v1091 and opened my latest old chartbooks running with v1091 and I migrated all my v1172 updated studies from my v1172 chartooks on each v1091 corresponding windows. I'm rather embarrassed because I don't have the problem of Datas swallowed/missing after the 15 min of calculation even with 3 big chartbooks running together. It seems that the buffer/the stack works fine with this version. Did you implement a different datas structure managing on v1091 Vs 1172 ?? Sure there must be something different....I'm really scared to be blocked working only with v1091 in order to keep my data files not corrupted as I still need to make regularly live update in my studies Can you help please. It would be very appreciated. Thank you in advance. Date Time Of Last Edit: 2014-08-22 10:17:30

When you say 15 minutes of calculation, is the Sierra Chart user interface in a frozen state during that time?

yes, all the graphic are frozen and all windows (displaying different markets too) of the chartbooks can't be moved during this time of calculation...but when it ends, datas recorded in the buffer (occuring during this time) displays correctly (without any gap) in the chart with SC_v1091 ; Amazing ! With SC_v1172, I have a data gap display of the last 15 minutes matching the calculation not only on the market of the studies of the chart I update but also with all the other markets opened in my 3 chartbooks. Thanks indeed for your kind consideration. |

We are testing this now.

We have done a test now where we have put Sierra Chart in a frozen state for about 3 minutes. Normally what should happen in this case is the TransAct bridge program should automatically shutdown. It is not. And the fact that it does not is a problem. However, we were not missing any data because all the data was received when Sierra Chart became unfrozen. We think we know what the problem could be from in your case. Make Sure Global Settings >> Data/Trade Service Settings >> Timestamp Using Local Computer Clock is set to False.
