Hi As the header describes, Replay mode stops working if (after it starts replaying) you press pause and then play again. It IS working fine in 1952.......untill i upgraded! Cheers

What version do you notice this with? It might be related to the new ACSIL functions to control chart replays. We do not notice this problem with 1967. We also do not notice this with prerelease 1970 either. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Hey guys, just been running 1959....the market is fast now (real time) and Sierra Chart for the first time ever slow as hell ... as slow as XTrader was years back when I switched over to SC. 1952 WORKS OK ..... I dont know what code your changing but its making SC run like a dying dog !!! Please review your code ..... play back AND very slow in fast markets (I am running latest i7 with 64gb ram and SSD drives ... so its not me!)

Regarding post #5, refer to: High CPU Usage \| Inactive User Interface \| Poor Performance \| Long Time to Load Chart Data \| Charts Reloading Often Nothing has changed between versions in regards to performance. In general newer versions have higher performance over time. But if you are using Bid and Ask Depth Bars study, refer to: https://www.sierrachart.com/index.php?page=doc/StudiesReference.php&ID=213&Name=Bid_Ask_Depth_Bars#ImprovingPerformanceOfThisStudy If you are trading CME markets we recommend using this data feed for better performance: Denali Exchange Data Feed Sierra Chart Support - Engineering Level Your definitive source for support.

I am totally confused now. version 1952 works perfectly with fast markets, playback etc etc Never had a problem with SC with regards being slow...in any way I go to version 1959 and its terrible (im not exagerating, its like the old XTrader at market close) .... this is a few upgrades over a week or so 1952 ---> 1959+? Surely such a degredation of performance in such a sort period of updates is no acceptable? It worries me that you point me to computer minimum specs as though this is the problem? arrrrrgh!!!! My computer is not a problem in this scenarion as mentioned in #5. Also, the playback problem with 1959 onwards? has this been fixed ? I have jumped over historic hurdles with issues but am i right in saying that performance is going to remain at this level? Like i say something terrible has happened because v1952 works perfectly, even the playback works without any problems? can you explain why 1952 works perfectly and a week or so later there's big problems?

Whenever we get reports like this, it really is impossible from our perspective, to know what the issue is. And there is always some other explanation than what the users think. It is not like the newer versions are slower. That is definitively not true and we would never believe that because it makes no technical sense. And if you are using CQG, CQG market data processing is going to be more efficient with market depth now. Make sure you have the Replay Mode set to Standard Replay: https://www.sierrachart.com/index.php?page=doc/ReplayChart.html#ReplayMode What is the replay speed? Also, the playback problem with 1959 onwards? has this been fixed ? We have not been able to reproduce a problem. Sierra Chart Support - Engineering Level Your definitive source for support.

Actually, we know what the problem is. In your most recent post you are mentioning 1959 and there is a difference in the way that version works with timers. There is not any performance issue, but there are more frequent updates. This is talked about here: Managing Performance with Version 1959 and Higher and the Chart Update Interval However, the current version of Sierra Chart which is 1967, does not have this change until we have more time to improve upon it. So if you update to 1967 you will not notice any change. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I've always used Calculate at Every Tick/Trade up until Version 1952 with complete success. Since v1959 this option stops working when you hit pause and then replay... Standard replay is OK but not as accurate in my experience. Can this option be fixed please to as it was before v1959. I will monitor the slow performance issues also. Thanks

See post #10 above. We know what the problem is. The reason we did not catch on to this at first, is that these messages were interpreted within the context of what is the current version of Sierra Chart which does not have any issue like you are describing.

OK I've upgraded to 1971, "accurate trading system back test mode" & "calc at every tick/Trade" still don't work AFTER you press pause & then play again....Only "standard replay" works using pause & play.... I'll check out performance at market open of 1971 (hopefully as you say, all fixed with that aspect 🙏)

I have transferred my charts across to a new install of SC v1972, still does it. Create new chart in new install and still does it. The only thing that works as it should is standard replay. Like I say, v1952 works completely correctly so there is obviously some changes that have effected this functionality, otherwise if it was me then v1952 wouldn't work either, would it? Performance is OK though in latest version 👍

Dear Support I'm not sure if this is related but I'm noticing sync issues between different markets on playback - standard replay - even at just 360X. Currently I have 4 different markets and identical the timeframes, 12 mins for example will be out of sync by an hour even after just 2 months of data replay. May not seem an issue but its important I keep them the same. I have tried it with skip empty periods both checked and unchecked, just in case this was causing an issue but it's still occuring. Is this to be expected? It wasnt an issue in the past. Currently on V1971 32Bit and 28 charts in chartbook. Many thanks Date Time Of Last Edit: 2019-08-13 19:34:36

There should not be any synchronization issues. Here is the relevant documentation for that: Replaying Charts: Automatic Skipping of Periods Where There Is No Trading and Synchronization You definitely need to keep Skip Empty Periods unchecked consistently during the replay. But you are also replaying months of data, so the question is what are the symbols? It is also important to make sure there is no missing data in those charts.

Thank you the documentation on replay is very useful and was my first source of reference. The markets being replayed are GBPUSD; EURUSD; USDJPY; USDCAD and all charts and timeframes have ASCIL studies. My understanding was that if I am not skipping empty periods and given that all of the data I'm using for this is 1 minute, then I'd assumed SC would maintain synchronisation across all markets and timeframes, irrespective of whether it was actually Futures, SPOT FX or anything else? 1) Just to be sure, is this the case, or is it likely I'll still lose synchronisation irrespective? 2) I'm not auto-trading, or using tick data so the documaentation suggests ther use of - accurate trading system back test mode - to maintain synchronisation is not necessary, in addition this setting causes an issue for me as I cannot watch the bars unfold. As stated in the - replay section - as it will jump bars. For example on a 3 minute chart it may jump from 15:39:00 to 16:03:00; making - accurate trading system back test mode - not suitable for visual playback.. Out of interest, when I replay using a specific - start date-time - I notice that USDCAD and EURUSD are almost immediately 1 bar ahead of the GBPUSD and USDJPY on the 3 min charts which grows as time elapses. On the 12 min charts when paused the EURUSD and USDJPY are almost immediately 1 bar ahead of the GBPUSD and USDCAD which is not even consistent with the 3 min chart at start? Certainly I'm a little confused by this and possibly missing something. Many thanks. Date Time Of Last Edit: 2019-08-14 08:19:22

Update - additional issue noticed. All Charts Standard replay Skip Empty Periods (not selected) Speed 360 28 charts comprising 4 markets in chartbook; resource monitor low; ASCIL studies/indicators running in charts; not auto-trading; data start JAN 2012. When charts go out of sync I pause and restart. Charts seem to re-align themselves. However, if I pause and go back << "To the next bar" one line of charts (7 for same symbol)go right back to the beginning of the data file 2007 with each showing just 1 bar at start of each of the 7 charts. When I select play the 2007 charts begin to replay while the other 21 charts (3 markets) are frozen (waiting for catch I suppose) at 2012-01-25; the date when paused. Another concern is that when paused the charts with the same market/symbol do not reflect the same price and are oftern few points out - even though I felt they were built from the same 1 minute data file? Concern here is that bars may form differently, during different replays, over the same data. Grateful for your thoughts Many thanks Date Time Of Last Edit: 2019-08-14 10:31:51

I have this issue whenever I choose accurate trading back system test and all charts in chartbook and start at specific time. It does not matter what speed I choose
