Heikin-ashi formula

[fish7]

I pulled up the Heikin-Ashi EFS and like it as an alternative to the usual price candles since it smooths out the action a little.

How do I throw up other studies on top of the HA chart (e.g., Moving averages, bollinger bands, etc.) ?

You can make copies of the studies you want to "throw up" on the chart and have setPriceStudy(false).

Or in the HA study, setPriceStudy(true).

Buzz, Thnx for your reply.

If I setPriceStudy(true) in the HA study, that just overlays my HA study on top of the regular price candles, w/out using the HA study results as input for any indicators I put on that.

If I make copies of studies and setPriceStudy(false) in them, and then overlay them on the HA indicator, eSignal forces the scaling of all studies to max-out at the high and the low of the indicator window. Hence, if I scroll back and forth, looking for simple Moving Average Crossovers, the results are meaningless as they depend upon the size of my window and the bar spacing. Is there a way to turn off this auto-scaling feature of eSignal so that I can do a simple Moving Average crossover study on HA ?

I encountered the same problems when I first played about with Heiken Ashi.

In the end I plotted what I wanted in the indicator pane along with the Heiken Ashi, making a rather large efs.

Paul,

How did you turn off the auto-scaling?

[fish7]

Paul,

For example, here is my HA study with the 21 and 34 ema's on it (blue = 24, black = 34). I show the chart at two different times, just 10 bars apart. As you can see, as time goes on, due to the auto-scaling, the "Moving average crossover" disappears in the 2nd file.

Here's the 2nd image -- could not load w/the prior one, together.

[pmurraymc]

There is no re-scaling it is all in the same efs.

Just more values returned, for each new study added to the efs.

Paul.

[fish7]

ah, I see. Gotchya.

Was hoping there was a more elegant way to do this than to rebuild EFS's for each time I want to try a different indicator on top of another.

Thnx for your time.

[pmurraymc]

I'm sure I have seen posts where the more educated efs users mention a way round it - but it has never worked for me.

It was interesting to add stuff and not get too confused.

Paul.

Hey, this may be a place where the reload efs comes in...

Maybe you could change the limits in setstudymin/max...

Hmmmmmmmmmm

[fish7]

Paul,

Could you pls post the EFS for what you have pictured here.

I'm stuck and got an EFS that keeps crashing on me when I try to make a Heikin Ashi indicator that has a 21 EMA overlayed on top of it.

Thnx

Hi Fish,

this thread from Alexis has a smoothing line on the Heikin Ashi, which I built my study on, and you won't have to struggle through my coding.

Thnx, Paul.

That helped a lot.

Cheers!

No problem, I always grab any efs on the board to see if I can learn from it.

Paul.
