the thread with the above title has been locked ZigZag & Swing Hi/Lo: SERIOUS ISSUE you claim this has been fixed but it has not. the ZigZag indicator still fails to repaint its printed values (from previous bars) for SG5 Accumulated Volume. you have locked further discussion on this issue prematurely. this is sloppy support IMO and discouraging. fix it, show the proof, do it right or leave the thread open and keep working on it. |

We will be reviewing this.

you may have fixed part of the problem but SG1 of ZigZag can be easily seen changing (whether in Spreadsheet or a reference study based on ZZ) upon recalculating the chart. what concerns me is the fact that i have to constantly Recalculate the chart in order for studies based on ZigZag to properly re-draw their recent past. rather, charts should update automatically, even if a derivative study like StudySubgraphReference is referencing a ZigZag SG. i should not have to Recalc manually to see past events relocate to their proper positions. i realize that a study like ZigZag is constantly re-evaluating the current swing; i just believe it should auto-redraw it on the chart (and ditto for derivative studies). thank you.

i should mention that i am seeing this behaviour in Market Replay mode (on any speed). i have not tested it with realtime market movement.

i have verified that the same non-repainting/non-updating behaviour of StudySubgraphReference studies based on ZigZag occurs both in realtime market mode as well as in replay.

This is going to be a problem and we cannot reasonably solve it: even if a derivative study like StudySubgraphReference is referencing a ZigZag SG. i should not have to Recalc manually to see past events relocate to their proper positions.

understood. but between this, and not being able to access bid/ask volume at exact prices within the bar (VAP[] not fully working), and volume profiles/Numbers Bars not drawn proportional to the values for the whole session or whole chart (comparing them within the bar is almost useless), SC is starting to seriously fall short of my needs.

SC is starting to seriously fall short of my needs. Therefore, we advise that you consider using another program.

We have now developed a solution for this kind of problem. We will make changes to Study Subgraph Reference to work properly under this kind of scenario.

It seems that a number of users have made comments about how the Zig Zag study does not calculate accurate swings in real time and a full recalculation needs to be down manually. In the documentation, you have said- "In the case of a chart bar where it creates a new low or new high for the current Zig Zag line and also triggers a reversal to start a new Zig Zag line, there can be a difference between the bar where the Zig Zag line reverses direction at between real-time updating of a chart and when a chart is fully recalculated like when selecting Chart >> Recalculate or modifying Study Settings. There is no solution to this. This is inherently just a limitation of the study working with complete chart bars because the Zig Zag study does not know how the chart bar formed within during a full recalculation whereas it can during real-time updating." Why can you not adjust the code to auto-execute the calculation following the close of each bar, or when a new potential ZZ point is reached? |

You are welcome to make the change. This is not something we would change.

Sure. *It's just that in the documentation you have said there is "no solution to this" So there is a solution, you just don't have time to implement it? Date Time Of Last Edit: 2017-06-20 06:26:44

We do not agree that there is a reasonable solution. We are not going to implement something that does not make sense to us.

At present, the ZZ study is only accurate on historical data. It makes sense to me to make it as accurate as possible on real-time data as well. Is there any documentation that shows how I might execute a recalculation? |

It is going to be most accurate as a chart bars are forming in real-time. A recalculation can simply be done with Chart >> Recalculate.

Sorry, I should have been more specific. The real issue is when referencing ZZ subgraphs. For example, using an Arithmetic( subgraph ratio): Zig Zag(SG1)/ Accumulated Volume(SG5) Correct values will not print in real-time. You must re-apply the study or recalculate. See image attached, historical( green)/ realtime( pink), and on the right is after the study is reloaded. -The same issue occurs whenever you reference any of the Zig Zag subgraphs -I'm trying to build real-time alerts from Zigzag subgraphs, so having to manually reload/ recalculate is not a practical solution. So I am asking if you can link to any ACSIL documentation on how I could programmatically execute a study reload/ recalculation. |

Neo, have a look at this thread: request for a very simple ACSIL study |
