Summary: IsReplayRunning() returns false on the last bar of a replay. I would expect a value of true. Connection Status: Disconnected Manual Replay settings: Mode: Accurate Use Start Date-Time: true Speed: 200000 Skip Empty Periods: true Problem: I need a reliable way to determine that I am backtesting. Is there is another method/property to determine this? |

The value of that variable must be accurate. So what you must be seeing, is the replay has ended when it is false.

Below is a log showing all study calls during a replay from 7/7/21 10:55 The last tick of available data is at 10:59:14 The study is set for manual looping The chart is configured for 1 minute bars Sierra Chart is disconnected Attached are the replay settings and the last tick of data for the symbol As you can see: IsReplayRunning is turned off starting at 10:58. Shouldn't this be set thru the last bar at 10:59? GetReplayHasFinishedStatus is set at 10:58. Shouldn't this be set at the 10:59 bar? The last bar of the replay (10:59) is called twice but with both flags cleared. Why is the last bar not included in the replay?

We have to look this over, but it depends actually upon when the study function is called in relation to the data read from the Intraday data file.

Any update on this? If this is not a bug, please explain why not. If it is, please acknowledge. Disappointing that you don't have a process to close tickets and are willing to simply leave them unresolved |

We have not had time to get to this yet. We expect to do it this week.

The problem is not reproducible at all. It is fairly involved to go through these tests, and this is why it was set aside until we had a chance. These tests were done with Accurate Trading System Back test Mode: Replaying Charts: Replay Mode This is with automatic looping: Chart: NQU21-CME[M] 10 Min #1 | Study: Test Function 2 | FinishedStatus. Index=212. ArraySize=213 | 2021-07-23 05:12:51.234 This is with manual looping: Chart: NQU21-CME[M] 10 Min #1 | Study: Test Function 7 | FinishedStatus. Index=202. ArraySize=203 | 2021-07-23 03:30:30.977 These messages occur just once at the end of the replay. And also understand the indexes are zero-based and will always have a value 1 less compared to the array size but they occur on the final bar. int FinishedStatus = sc.GetReplayHasFinishedStatus();
if (FinishedStatus) { SCString Message; Message.Format("FinishedStatus. Index=%d. ArraySize=%d", sc.Index, sc.ArraySize); sc.AddMessageToLog(Message, 0); } Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

The problems are 100% reproducible. Since you didn't share your code or complete log, I'm not sure what you tested but the attached code and output clearly show the following issues. Problems: 1) Replay stops 2 bars before the last bar. I would expect replay to replay thru the last tick available 2) The last bar is sent w/o any replay flags (IsreplayRunning, GetReplayHasFinishedStatus), recalculation flag, or reset of index. This is truly an invalid state and looks to the code like real time data but is in fact replay data. 3) Per the current GetReplayHasFinishedStatus() documentation, I would expect to see a final callback of the last bar "one more time" with GetReplayHasFinishedStatus flag set to indicate that the replay has completed. If that's not the case, it would be great if you'd update the documentation to match the functionality. Currently the flag is set prior to the last bar. This code run while disconnected with the attached replay settings: #include <sierrachart.h>
SCDLLName("ReplayTest"); //DLL name SCSFExport scsf_ReplayTest(SCStudyGraphRef sc) { if (sc.SetDefaults) { sc.AutoLoop = 0; sc.AddMessageToLog("SetDefaults",0); return; } if (sc.LastCallToFunction) { sc.AddMessageToLog("last call",0); return; } SCString s; s.Format("%s index:%d recalc:%d replay:%d finished:%d", sc.DateTimeToString(sc.BaseDateTimeIn[sc.UpdateStartIndex],FLAG_DT_COMPLETE_DATETIME).GetChars() ,sc.UpdateStartIndex ,sc.IsFullRecalculation ,sc.IsReplayRunning() ,sc.GetReplayHasFinishedStatus() ); sc.AddMessageToLog(s,0); } Produces this output: Chart: ESU21 [C][M] 1 Min #1 | Study: Custom DLL Study | 2021-07-26 14:05:00 index:8164 recalc:0 replay:0 finished:0 | 2021-07-26 16:32:01.552

We still have not had a chance to look at this, but one thing we want to know is this a multi-chart back test using a Processing Step in Seconds? The behavior might be different in that case. That has not been considered as to how sc.GetReplayHasFinishedStatus() would work in that case. Sierra Chart Support - Engineering Level Your definitive source for support.
