hello support , Im having issues with historical chart replay . While paused the DOM is still moving as is the foot print . My request to replay my full chart book is all skewed playing different price points. The pop up save trade history reoccures and is different for each chart in my chart group. Play/ pause only effects certain charts and not others . I nave dom , market profile , VWAP , delta charts up but they all seem to jumble in the replay . Please help me before my PC ends up out the 5 story window . Thanks |

The first thing is to make sure that you are replaying the charts that you want to replay. Refer to the following option on the Replay window: Replaying Charts: Charts to Replay And then refer to the following regarding keeping charts in sync: Replaying Charts: Preventing Loss of Synchronization Between Different Charts During Replay For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Hi, The replay is so fast even at 2x speed and i wonder how/ why can I trust the quality of the replay as You claim it suppose to reflect as real as possible realtime market conditions, while it works so fast... Does it still consider all the tick data - last prices and last bid-ask volumes- from the data file? I ran the footprint chart and sometimes I really saw only glimpses of the chart at 2x speed... Haven´t made any studies with calculations yet. May-be that brings the speed down a bit. Though have experienced the MT4/5 backtester speed... also really fast, but they claim its not reflecting the realtime market conditions of course... And read that Zorro (C-lite) can optimize 12 characters strategy with tick data in 25 seconds > https://zorro-project.com/features.php) > have not experienced that... Compared to NT8 = got sctuck at 10x speed at around 13:00 running from 07:00... Hope the strategy optimizer is under dev, right? > Optimization and Strategy Report Thnx. |

The replay considers all the tick data. When you increase the speed of the replay, the system is just processing the data at a faster rate since it is already in memory, as opposed to live, where the data comes into the system whenever it does. The reference you make to the old thread regarding 'Optimization and Strategy Report" states that it is not something we are working on. We are not even sure what is being asked for in that thread at this time. The original post was from 2015.

The general rule is that the study is called whenever there is new data or an order update. But, you can force an additional update at each "Chart Update Interval" by setting the sc.UpdateAlways variable. Refer to the following: ACSIL Interface Members - Variables and Arrays: sc.UpdateAlways In the end, your study will get called often enough. If there is an issue, then most likely it is something in your code not doing what you are expecting. We know nothing about MT5 and we do not pay attention to what other systems do. If you are looking for something specific, then we need to know what exactly it is. We have no idea what you are looking for in terms of "optimization".

Thank you, basically optimization func is making 1000-s of backtests (or replays) with different settings starting from one value, steps of values and final value * different parameters. Based on that making report ranking the best values targeted. Doable?

This is not something we would do in relation to a custom study. The system does not know anything about your study and what parameters you would want to change. It is fairly simple for you to do this yourself. You can have one study that controls the backtesting and adjusting parameters for another study. Refer to the following: ACSIL Interface Members - Functions: sc.StartChartReplay() ACSIL Interface Members - Functions: sc.SetChartStudyInputInt() For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |
