Hi, I have like 8 charts in my chartbook and when I replay with the option to replay All Charts in Chartbook, some of my slow loading charts fall behind. My slow loading charts take a couple of minutes to load but I start the replay from a short timeframe chart which loads in 2 seconds and starts replaying. Is there a way to make sure the replay of all the charts doesn't start until the data is fully loaded in all of the charts? I am using the Standard Replay with a speed of 30. I tried with Skip Empty Periods checked and unchecked, with the same result. Thanks. |

With regards to the charts staying in sync, refer to the following: Replaying Charts: Preventing Loss of Synchronization Between Different Charts During Replay With regards to the time to load, the only option is to start the replay further back to help the other charts load and get caught up.

Thanks. I have followed those directions. Also, starting replay further back is unlikely to help because the difference in load times between charts that load like 3 - 10 days versus the ones that load couple of years worth of data is above 2 minutes. The charts with smaller number of days start the replay as soon as they finish loading. Is the moment we click Play to start the replay the only controlling anchor for keeping all the charts in sync? If so, from there each chart then optimistically stays in sync for as long as it can depending on the other documented factors on SC.com, is that correct? If the above info is correct, I would urge you to delay the replay of all charts until the data is loaded in all of the charts. This will improve the chance of all charts running in sync significantly. If I have 6 to 8 charts, the longer I run the replay, more the chance of charts getting out sync and if I start replay with some charts being out of sync by 2 minutes at the outset, then there is almost no chance that they will later synchronize themselves. Thanks. |

Sorry to hijack this thread, but I would also like this to be the case.Currently, the replay starts when the initiating chart loads, with the other charts still loading. If there are overlays that formulas rely on, they are not synced until all charts are loaded. The only workaround is to start the replay much earlier than desired, guessing how long it takes the other charts to load. If the difference in the bar periods of the charts is great, it might not even be possible to start the replay early enough. Even if the replay is started early enough, it might take erroneous trades until the charts sync, invalidating the backtest accuracy. |

Please comment on #3 post above. It would be a great enhancement to make the replay work better for multiple charts with a lot of data loaded. Thanks.

We need to think about this.

What we are going to do is to add a new option to the Replay Window to start a replay paused. And then you can continue when all charts are loaded. All the charts that are replaying, have the very same starting Date-Time set for them which is used as a reference point and they will stay synchronized unless empty periods are skipped.

After updating from version 2443 to the current version, 2457, the chart replay function replays for one defined time interval (60s per default or any other user defined interval) and then automatically enters in pause. One has to press play again to have another time interval played and then the replay pauses again. All settings having remained the same as in the previous working version. Maybe this is a bug introduced by the above option that has been added or a new functionality introduced elsewhere. I could not find anything similar to this in the release documentation. Can you pls help?

When you notice this, does the replay status at the top left of the chart actually say "Paused"?

When I press play, it says "Replay". After a few seconds, it reverts to "Paused" and the chart stops replaying.

It sounds like you have not scrolled the chart back to where you want the replay to start from. Or, the other option is to enable the setting for Use Start Date-Time rather than scrolling the chart.

Your diagnostic is incorrect: Not only I always use "Use Start Date-Time", but I have also stated in my original post that the replay function was working fine before the upgrade, but not after; in fact, I decided to roll back the installation to version 2444 and the replay is working again.

We always have to start our diagnostics with the most probable and simple situations. You would be amazed how many times the item simply is "not plugged in". But, with regards to the replay, what you are stating should simply not be occurring. We do not see any issues with the replay. What version of the software were you on when you had the issue? Also, what was the Start Date-Time set to? For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

We are not able to reproduce this. There is a new setting on the replay window that says "Start Paused". Make sure this is not enabled.

It is not enabled; which version has introduced the new setting on the replay window that says "Start Paused"?
