Price Alert Common Window

[philtong]

Is there a common window where I can view price alerts, other than the debug window?

What I'd like to do is at the end of the day, see if any of the 20+ charts have met a condition. I'd like to view them in one window. Is there a way to do that?

I guess I can try to write to a file... but I wonder if there will be any file access conflict when more than 1 chart tries to do this at almost the same time?

Hello philtong,

Yes there is such a way. What you will need to add to your formulas is Alert.addToList(). This function will add an Alert to the Alert List window. Any alerts from your charts will all be populated in this window. Make sure you have Pop Up Alerts enabled in the "Set Alerts" option under the "View" menu if you want the window to appear as alerts are triggered. You can also open the Alert List window manually by selecting "Alert List" under the "View" menu. If you open the Alert List window, you can also right-click on it to view the window's menu choices. This window is set to display a maximum of 50 alerts. If you anticipate receiving more than that, you can increase that number in the properties option from the right-click menu.

    // Alert.addToList(Symbol, Description, FG, BG)
    Alert.addToList(getSymbol(), "Buy", Color.black, Color.green);

Is there a way to log alerts without the Alert List window 1) popping up, and 2) taking active window focus?

For example, writing to a DateAlertLog.txt file?

Hello Lancer,

You certainly can write to a file. Here's how:

function preMain() {
    setPriceStudy(true);
}

function main() {
    var a = new File("myfile.txt");  //the file will be created in:  eSignal/FormulaOutput/
    var myData = 25;  //  example data
 
    a.open("w");   // Opens and overwrites the file
    //a.open("w+"); // Opens and appends to the file
    if(!a.isOpen()) {
        debugPrintln("Could not open file!");
    } else {
        a.writeln(" build a text string, " + myData + " more text etc. ");
    }
    a.close();
} 

Please note: If a formula tries to open the file when it is currently open by another process, the alert will not get recorded. I'm sure it would be a very rare occurrence, but it's something to consider. To ensure that all alerts get recorded, one could have each formula write to its own file.

Hi Lancer:

Here is a self-contained function that will create and update log files. It will initially create a log file with the symbol name + date (e.g., IBM02-23-2003.txt). Each line will be time stamped and you can pass as many parameters as you want to this function

Example:

logEntry( "hello" );

will write 16:23:03 : hello

to the log file

logEntry( close(), high(), x+10/3, "Stop Hit" );

will write something like:

16:24:17 : 89.34, 90.23, 15.6, Stop Hit

Here is the function, just place all of this at the end of your EFS file (after main() ). The log files will be written to your formulatoutput directory. Click on "Tools" and then "EFS Settings" to find out where that is. In case it is hard to read in this message, I will also post it up to the Specialty Groups - Miscellaneous section.

    catch( e ) {
        debugPrint("File Error: " + fStamp + "\n" );
        return;
    }

Any reason


Alert.addToList(getSymbol(), "ShortEntrySignal", Color.RGB(0,0,0), Color.RGB(195,0,0))

wont show up in the Triggered ALert List?

I am very sure the line of code was executed.

I just ran a test and it shows up in the Triggered Alert List when the conditions are met.

I added a debugPrintln before and after the alert line. The debug line prints ok, but not the alert.

if(bar=="red" && barOld!="red"&&arrow!="short"){
setPriceBarColor(Color.yellow);
//Alert.playSound("C:\\Program Files\\eSignal\\Sounds\\Ding.wav")
Alert.addToList(getSymbol(), "ShortEntrySignal", Color.RGB(0,0,0), Color.RGB(195,0,0))
barr=barr+1;
arrow="short";
bar="yellow";
//if(getCurrentBarIndex()==0)
debugPrintln("ShortEntrySignal");
drawShapeRelative(0, low()-0.25, Shape.RIGHTARROW, "", Color.RGB(255,251,240), Shape.LEFT, barr)
}
