Opening Range Time Parameters

[whinston]

I tried copying this formula from this http://forum.esignal.com/showthread....5&pagenumber=1 thread, and adding the function that Alexis recommended in the main function. My script now looks like this, but I get an error message in line 58 which states that efsInternal is not defined. Does anybody know what that means?

Thanks,
Whinston

FWIW the formula you posted is working fine as you can see in the enclosed screenshot

Re: Re: How to plot the opening range?

Thanks for trying it out. Unfortunately, it seems to give an error on my machine. I quoted it exactly (in fact, I simply copied and pasted it here). So why am I getting this error message? It says:

Wizard\WhinstonsEFS.efs, line 58: Reference Error: efsInternal is not defined.

Thanks for any further insight,

What version [and build] of eSignal are you running (see under Help->About)?

I'm using build 7.6, build 636A.

Sorry it's not the newest one, but I love this version and I don't want to upgrade. Hopefully you can figure out for this version.

Thanks,

The formula uses several EFS2 functions amongst which efsInternal() which were introduced with version 7.9 [build 719] and are not available on earlier versions so if you want to run it you will need to upgrade

Ok thanks. I'm considering upgrading, but before I go to that trouble, could you possibly show me a screenshot of a 3-minute chart with this EFS? Previously you had showed me a 15-minute chart, but what I would really like to see is a 3-minute chart.

I do realize that the EFS is calculated on the first 15 minutes of trading.

Thanks so much,

Line 11 and Line 12 of this EFS state the following:

setDefaultBarFgColor(Color.black,0);
setDefaultBarFgColor(Color.black,1);

I'd like to change the color to an RGB color, such as 71,94,79.

How would I go about doing this?

Thanks for any info,
whinston

[whinston]

Forget it, I just figured it out... Thanks!

[whinston]

If anyone is interested, the two lines would look like this:


setDefaultBarFgColor(Color.RGB(71,94,79),0);
setDefaultBarFgColor(Color.RGB(71,94,79),1);
