How to get an alert

[averyhorton]

I am new...

If you could please show how to do that in the lin reg alert, I would appreciate it.

Further to yesterday's exchange on chat I just remembered that there is a much easier way to set the LinReg efs to emulate the Linear Regression Channel available with basic Charts.
Rather than having to count the number of bars loaded in a chart modify this line in the efs.

var vLinReg = new LinearRegressionStudy("HLC/3", 64, 2);
to
var vLinReg = new LinearRegressionStudy("Close", 0, 2.5);

The value of 0 sets the LinReg to include all data in the chart. As an aside one other item which may have accounted for the slight differences you were seeing between the two was also due to the fact that the efs was using HLC/3 whereas the Linear Regression in the basic Charts is probably using Close only, hence the change in the line above.
2.5 is the Std Dev as already mentioned yesterday.

Avery,

Attached is the EFS with pop-up Alerts added, and the sound changed to doorbell.wav. Also included is Alex's suggestion.

re changing the chart color

You could add

setChartBG( Color.yellow ); to the section of code sends the alert

Lin Reg...

Thanks everyone for your help.

It is so nice to find a community of people willing to help out a new guy.

One thing I notice if that the Basic Chart Window Linear Regression is "wider" than what I can get in the Advance charts...

The Lower LR line is the most important one to me.

It looks like the Upper LR in the Adv Cht is close to the LR (middle) line in the Basic Chart.

I really appreciate you guys taking the time to code the pop up.

Wish I had it earlier.. could have made a few hundred of off SONS!

As we discussed yesterday you need to make sure you are comparing apples to apples, i.e. both charts must have the same number of days/bars.
FWIW I ran a check across a number of securities and the differences can range between nil and maybe 3 cents over 1500 bars.

Thanks for your reply.

I would be happy if the upper and lower lr was only off by 3 cents... but it is a whole lot more.

I just can't see to get the two to sync up.

Avery,

Can you give some examples of symbols you are seeing large discrepancies with? Perhaps some screenshots would help as well.

To save a screenshot (image) of what you are seeing, click on the eSignal Snapshot icon in the Windows System Tray to bring up the Capture Window.



Then drag the crosshairs to the chart or charts you wish to grab an image of until they are highlighted in a red square. The Image Publisher will then display. In that window, you will want to select Save to Local File and then Browse to where you wish to save this file.



After the file is saved, you can then attach the image file to your post by using this function.

Here is but one of the many I have tried. The difference is 1 cent on the Upper, 3 cents on the lower and 0 on the centerline over a 5 day period.
Other than that I really would not know what to say.

I could do that but first, Please

pull up the charts on your system for CHTR and AMR

and tell me what your settings are for the basic chart window, advanced chart window and what the settings are in the lin reg formula.

I am using 2 days data, 1 min interval, tick filtering and 5:00/16:00 open/close times.

You may recall that yesterday Jay said that if one uses trading hours outside of RTH you are bound to see differences because of the different ways data is handled in the two charts. Basic charts show all periods whereas Advanced Charts omit periods with no trades.
If instead one compares apples to apples ie two charts with the same data then the results are yet again within a few cents of each other as can be seen in the following chart.

Ok I will set my charts to RTH and see what happens.. thanks again.

Hi,

Did they ever fix the wav issue where you can change the wav sound from a ding?

Thanks as always for all your help,

I believe it has been fixed in the beta version (latest build is 578). If the wave file is in eSignal/Sounds folder you can simply type the name of the *.wav file without the directory and the change will take effect.

LIN REG STILL NOT CLOSE
