View historical values.

[redbaron1981]

Hi Guys,

First post here so apologies for being new. I did try the search button before posting here so if my question is repeated apologies.

I have the ACD indicator(See Attached).

Is it possible in Esignal so that I can see historical values of this indicator on the chart?

It only displays current values but no historical and so is little use in this current state.

Any Help would be much appreciated.

Thanks.

RB.

I think this does what you asked for.

Hi Wayne,

Thanks for trying to help out.

I tried the code and it compiled fine however I still seem to have the original problem of seeing the levels from past days.

Do you think its anything to do with my esignal configuration?

All the best,

James.

[waynecd]

Use this revised version. My original repeated the current days price.

xMin Range_ACD LInes All.efs

It only displays current values but no historical and so is little use in this current state.

I expect menu settings are the issue:

The first thing to note is that the efs does not draw on daily, weekly, or monthly intervals.

Here is an explanation of what the added menu items do.

Menu Item Titled:
"# Of Days To Display": if set to 1 it will display one day so increase the # to have it draw more days
"Display Past Price Labels": checked=the price will be displayed for days in the past, unchecked= they won't be drawn
"Price Label Font Size": modifies the size of the displayed price font
"Past Price Line Length": modifies the length of the drawn line for past days
"Bar Index To End Todays Line": sets position of displayed price only for the current day

Play with those settings on a 60 min chart that displays several days so you can easily see what they change on the chart.
It will draw the same on other non daily/weekly/monthly intervals.

Hi James,

Just in case that what you are asking for is for the lines to extend to the right edge of the chart past the most current bar: It can easily be done but you will end up with a mess of lines indistinguishable as to origin date for dates not displayed on the chart.

Hopefully that made sense.

I corrected an error so it's best if test/use the following version:

xMin Range_ACD LInes All.efs

Wayne,

Thanks so much for helping me with this. It works perfect and just needed a few tweaks as you suggested.

I have just migrated over from Tradestation and the Esignal is nothing like easy language like I am used to.

In the future I will be looking at modifying this indicator so that the tick value is a percentage of TrueRange over 10 - 20 days so that it adapts for changes in volatility.

I also intend on creating 3 more versions of this indicator one to display levels on a weekly basis using 1/2 trading day for the opening range. A monthly indicator using the first day of the month for the opening range and quarterly which will use the first week of the quarter for the opening range.

Do you think that a noob would be capable of completing these projects? If not would you be interested in this work or can you recommend a programer for this? How much would you say that I would need to budget for these modifications?

All the best,

James.

James,

Your welcome.

I am not a programmer. I like you, had an interest. I just jumped in and learned it. The programming you describe is not so complicated and something I believe you can do after overcoming the learning curve.
Here are some resources:
eSignal File Share (for sample and functional scripts)
Forum searches yield answers to the majority of efs programming questions.
as well as resources listed at http://www.esignal.com/community.aspx?tc=

If you prefer a paid programmer here are eSignal web pages for that:

Developing eSignal Formula Studies
Formula Developers. Divergence Software, Inc. was used by an acquaintance who was pleased with their work and price. I haven't used them.
