Heiken-Aishi Bars.

[Eric1704]

How do I get Heiken Aishi Bars on my chart? I found the study in efs but it plots the bar in a separate pane. How can I get it to plot the heikin Ashi bars on my price pane itself? I would like to use HA bars rather than regular bars.
Thank you.

Hi Eric,
Is the attached similar to what you are looking for?

Thanks Diane. I tried that but it plots the HA bars besides the regular bars on the same pane. Is there way you can only have HA bars on pane rather than both types?
Thank you.

Eric,
I minimize the chart bars & increase the size of the HA bars & it works well for me. Sorry it doesn't help you. You might try changing the color of the chart bars to match the background color of your chart & then apply the HA study.

[Eric1704]

Thank you.

How do you minimize the bars Diane? I will try changing the colors on the chart too.
Eric.

[Eric1704]

Thanks Diane. I will try changing the colors. How do you change the size of your bars?

Hi Eric,
At the top of your chart screen, you should have an Advanced Chart ToolBar.You'll see a thick bar & a thin bar on that toolbar. If you click the thin bar, it will make your bars thinner thus smaller. Hope this helps.

OK, let's ask this another way.
How do we modify the chart to display the bars using the Heikin-Ashi OHLC values and NOT over-wright the display? I don't want to resize my bars everytimg I resize or rescale my chart AND I want to be able to use OHLC bars OR candlesticks and have the display reflect the Heikin-Ashi values. I guess what I am asking for is a Heikin-Ashi modifite to the various "chart types". Is that possible in and EFS? Thanks in advance, Dennis

[Diane P]

Hi Dennis,
To my knowledge, there is no "blank" price chart on which you could display only Heikin-Ashi bars. The chart types would display their indicated types, ie., a bar chart would display bars. A candlestick chart would display candlesticks, etc. I don't believe there is an efs that would do what you are asking.

Diane,
Thanks for the reply. I really think this is a short coming of eSignal that would be easy to correct and/or implement. The calculation is quite simple and would not require a significant amount of CPU time. I think I'll send it in to the "development team" as an upgrade suggestion.
Dennis

[Eric1704]

Thank you Diane and Dennis. That is what I was trying to figure out. Just plot Heikin Ashi bars only on the chart. Sorry for the confusion.
Thank you.

Hi Diane,

Thanks for posting the coding for Heiken Ashi bars. I noticed in the coding notes that it creates only the last 200 bars of HA bars, is there anyway to increase that number??

Thanks for your help.

Hi Kanirajan,
1) In the main, add "nLength" .(without the quotation marks).

2) At line 114 insert, if(nLength==null)nLength=300;(or whatever number you want). I haven't tried this, but hopefully it will help.

Hi Diane,

I'm not sure what you are referring to when you say the "main". I don't have much experience with coding on ESignal. Here is what I have:

Hi kanirajan,
On line 112 you will see function main. After nKAMAPeriods, and before the close parenthesis, add nLength. Hope this helps.
