Periodicity not shown correct on chart/chart header

asked this on February 23, 2011 02:29

MD 10.3.6. User since april 2010. Problem occurred for first time when I started to use the Delta option as periodicity. Prior to this I could change and use any periodicity I wanted without any issue (but I never used the Delta periodicity option before !).

Issue: When I change a chart to a Delta periodicity I often see the chart header description being corrupted. In the piece that is generated by MD it says: @EU# (200d), @EU# (200d) 200 POC Vol, Session 31. Now the 200 POC Vol part should indicate 200 Delta. When I change to other Delta values, back to other periodicity values, then my chart may become in a state where I can not change the periodicity. I can select a periodicituy in the chart properties, but the selected value may not become effective in the chart itsself. In the end I can only delete the chart and build from scratch. All periodicity selections will work (minute, range,volume, renko) until..... I select a delta periodicity.

What also happens: after 10 minutes - or 2 hours - suddenly the chart shows the correct header information. I tried to refresh data, recalculate the chart, logoff/logon to MD in order to get a correct chart header, but htese actions seems not to be working. Only time seems to solve this issue.

Question: It seems as if the Delta periodicity is causing a different behaviour. I woud like to use the Delta periodicity as any other periodicity in MD. In the trading room I m I see that the moderator sometimes has the issue where the chart header will not display the correct periodicity as well. So it seems as if this issue is not related to my PC only.

Issue occurs with both DTN IQ and Transact data feed.

I realize this issue seems vague to you, so please let me know what other information I may supply to you. I run a i5 based 8Gb memory with latest MSI motherboard series on Windows 7 professional.

I will include one chartdefiniton fro TFH1 (Russell) on Transact. Here the header says in the MD generted part of the header: TFH1 (0.1Re) 1000 minutes, session 31. I will also include a screenshot of the chart and you can see that this is not a 1000 minute chart !. Whatever I select on periodicity, I do not seem to be able to get rid of the 1000 minutes mentioning. I know that a solution is to delete the chart and start all over again. But the case is here that all works fine until i use a Delta periodicity. That is the case: the usage of Delta periodicity just like any other periodicity.

Thanks in advance for your reply.

Hi Michael,

This particular chart is one of the more complicated L2ST charts. It has multiple periodicities and elements on it and it does not respond to normal changes in periodicity. You have to individually change the periodicities of all the elements if you want them to all change.

I'll admit it's a bit tricky working with this chart, and for charts like this it is best to query the actual individual that developed it. I can't easily tell if the pane title issue is due to the multiple periodicities or perhaps the chart has become corrupt, as can happen after extensive manipulation of a chart such as this, which is loaded with many different elements.

Also, this chart is using Renko periodicity and there are different ways to create Renko bars in MarketDelta, one of which is quite sophisticated.

When I manually change both symbol elements on this chart to 5 minutes or 200d, for example, then the pane title works as you'd expect. So probably that is the issue. But I'm not sure if the developer planned for only one element to be a Renko while the other element was an alternative periodicity.

Hi Andrew,

Many thanks for your clear explanation. I queried the knowledge base and tried to find an answer on how to change the periodicity for each element, but I do not know how. I always just right mouse click in the main pane and change the periodicity. What else should I change to reflect the new periodicity to all elements? I would appreciate your guidelines here.

Thanks in advance.

Hi Michael,

Double-click your chart and you will an element list. Don't double-click on any actual bars or indicators, just a blank part of the chart's background.

Then you will see all instances of the symbol, like multiple TF items, for example. Double-click one of these and adjust the periodicity in there. Then when done, do it again for the other TF instance.

Once the two elements are aligned to the same periodicity, you may find that they change together when you change one or the other using the simple technique you already know.

Cheers.

Hi Andrew,

Thank you very much for your patience with me and the clear way you explain things. I highly appreciate this. Your guidelines seems to solve the issues I encounterd. I do have a small request: could you please delete the chartdefinition attachment I sent to you as this chart originates from L2ST and as such I feel their intellectual property should be protected. I think it would not be appropriate if any third party simply can download these chartdefinitions from this forum. If it would a chart I developed myself I would have no issues at all. The screenshot of course can remain in order to be of help to the forum members who also encounter this issue and also would like to learn from you.

Thnaks again for all Andrew !
