Heikin-ashi Chart Display Peculiarity

[blackhawk]

There appears to be some sort of a display peculiarity with Heikin-ashi charts - love them by the way and thanks for all the "variations" you have produced.

I have no problem producing Heikin-ashi charts and they seem very effective. I am also aware of the limitation in displaying >200 bars as currently specified within the efs. However, if you open another window partially over a Heikin-ashi chart, the Heikin-ashi display seems to simply disappear to just a series of "foggy" dots, especially if you pass the cursor anywhere over the partially obscured Heikin-ashi chart window. This also happens if a non-eSignal window is opened over a Heikin-ashi chart. If that eSignal or non-eSignal window is then removed, the Heikin-ashi chart still appears as a series of dots but the full display will re-appear just by passing the cursor over the Heikin-ashi chart - you only have to pass the mouse over the display, not even click the mouse. Is there a specific reason for this display problem since it does not occur with normal candlestick charts or any other eSignal charts?

Thanks

Hello blackhawk,

I was able to reproduce the screen refresh issue with the Heikin Ashi studies. However, to force the study to refresh I had to click on the chart or the study pane. A simple mouse-over did not refresh the study on my machine.



I've tested the same scenario with some other studies that use drawn objects and everything was fine. But I don't think there is something specific in the code responsible for this. It may be exposing some unique graphic display issue with lines drawn with drawLineRelative() in the way this study does. I'll send a note about this problem to development.

Just for you knowledge, the dots that you see beyond the most current 200 bars are the data series for the Heikin Ashi bars using the plot type of PLOTTYPE_DOT. These are the returned data series for the study that allows us to view the OHLC data for the HA bars in the cursor window. The wick and body of the HA bars are drawn using the drawLineRelative() function to create the bars for visual purposes only. This is the only way to create candlesticks from within EFS currently.

Thanks Jason, that is exactly the type of display I am getting if you overlay the Heikin-ashi window with another window - it fades out to a series of dots. Hopefully this graphics display issue will be corrected in a future version of eSignal.

Please have a look at the Heikin-Ashi-Graph.

eSignal is just plotting the dots, refuse to display the candles.

Do You know what went wrong, running this efs?

There are several versions of the Heikin-Ashi efs so it would be useful if you could also add a link to the specific version you are using

Surprisingly the H-A-Chart today is shown correctly. But I watched this some times before. One day it works fine, sometimes not.

Restart of eSignal did not help to solve the problem yesterday.

FWIW it appears to be working fine at my end on daily and intraday charts for all the symbols I tried

Just after my posting I opened a new chart, trying to draw a H-A-Chart. In this new chart window eSignal refused to display the candles again.

So in one window the H-A-Chart is shown correctly, in the other one not. Seems it has to do with some settings or parameters.

One reason to work with the Heikin-Ashi-efs is, to modify it for charting a candle chart in overlay.

I am not sure I understand what you are trying to accomplish.
Irrespective I have been running the Heikin-Ashi efs concurrently on multiple charts with different symbols and intervals and so far I have not seen the problem you reported

Heikin Ashi screen view issue

Hi there,
I have had a similar issue with regards to the screen view on Heikin Ashi charts. I am not sure whether anyone can help, but I had this study developed by TS Support in version 7.6. I had to lay off the trading due to other commitments for a while. I loaded up the latest version of 7.9.1 and now the study doesn't work. The guys at TS Support have been very good and they are adamant that it works on their PC. Can someone please put me out of my misery and tell me what the problem maybe before I lose anymore money? Please be gentle.

Many thanks in advance

The Heikin Ashi study is set by default to draw only the last 200 bars (see enclosed image).
If you want it to draw more historical bars open the efs and replace 200 with a higher value in the line
if (iCntr > 200) iCntr = 0;
Note however that drawing more graphical objects will use more resources (hence the reason for this limitation in the script)

Tried HA download but it doesn't display

Alexis thanks very much for your response. I tried out the downloadable version on this thread and I still get the same results. I am looking for some additional inspiration now. Any ideas

I created a chart for the same symbol and interval as the one you posted and set it up using also the same settings (Time Template, colors, etc) and studies you are showing. As you can see in the enclosed image the Heikin Ashi study is working fine (note that I have even put the Cursor on the same bar as the one indicated in your chart ie 11:10 EST which corresponds to your 16:10 GMT).
The one difference I am seeing - and I am not sure it is related to the issue you are having - is that the price values in both your Cursor Window and Y-Axis are not showing all the decimals.
Is the chart you are using carried over from prior installations or was it created from scratch since you installed 7.91?
Also is the default Advanced Chart carried over from prior installations?

Alexis,


The study was created in version 7.6 I believe. I had to take some time-out from trading I while back. For some reason I had lost the original 7.6. Therefore I loaded the latest version 7.9.1.

I am going to show my naivity now. To be honest, I only know how to load up the advanced chart by doing File then right down the bottom I get Advanced Chart. It is this version that is currently saved I believe.

You might need to walk me through how to set a new one up from scratch. Perhaps that may work I don't know.

PS I have put the cursor over the last bar which seems fine
