reset/rearm sound alerts

[stockwolf]

I need some help in resetting/rearming sound alerts other than reloading formulas Is it possible to create a reset text box? or some other way to rearm the alert once the alert situation has been dealt with from a trading or maintance standpoint?

TIA

Hello stockwolf,

You could use a text button to rearm an Alert. There's many ways to control this type of action depending on the specific logic of your formula. It sounds like you have a situation where the Alert is being triggered on every trade once your alert condition is true. If you only want the alert to be triggered the first time during the bar interval, take a look at AlertOncePerBar.efs. This example rearms the alert condition once a new bar starts and will only allow the alert to be triggered once per bar.

Thanks for the reply Jason, I should have provided a bit more information. The problem that I am having is the alarm is sounding on every tick, I have included here the portion of code which paints chart bars the same color throughout the entire cycle of a BUY or a SELL, and this is also where I am attempting to have the sound alert called from. Perhaps the sound alert needs to be called from a different location or by a different method

else if(BAMMSValue > vSMA)
setPriceBarColor(Color.green);
setBarThickness(2);
setBarFgColor(Color.green);
Alert.playSound("C:\\Documents and Settings\\My Music\\outthere.wav");

} else if(BAMMSValue < vSMA) {
setPriceBarColor(Color.red);
setBarThickness(2);
setBarFgColor(Color.red);
Alert.playSound("C:\\Documents and Settings\\My Music\\hello.wav");
}

Thanks for your help

Hello stockwolf,

You need to incorporate some global flags that only allow the alerts to trigger the first time the condition is true. The example formula I pointed out in my previous message uses this method.

Your code would look something like below.

else if(BAMMSValue > vSMA) {
    setPriceBarColor(Color.green);
    setBarThickness(2);
    setBarFgColor(Color.green);
    if (bLong == false) {
        Alert.playSound("C:\\Documents and Settings\\My Music\\outthere.wav");
        bLong = true;    // global var
        bShort = false;  // global var
    }
} else if(BAMMSValue < vSMA) {
    setPriceBarColor(Color.red);
    setBarThickness(2);
    setBarFgColor(Color.red);
    if (bShort == false) {
        Alert.playSound("C:\\Documents and Settings\\My Music\\hello.wav");
        bShort = true;
        bLong = false;
    }
}

Thanks for the help Jason, after inputting the flags like you suggested I am getting an error which tells me that "bshort is not defined"

Thanks again

Hello stockwolf,

You need to make them global variables by initializing them outside of main().

var bLong = false;
var bShort = false;

function main() {
...
...

Great and thanks Jason, that did the trick.

Well, I'm not much of a programmer, unfortunately the gal who has helped to put my ideas into code form has MS and is not doing well. Anyway, one last question, and I really do appreciate your help, how can I get the alert to sound at the Close of the signal bar, for example, when the alert sounds now, if the bar changes from red to green and back to red then to green on the same bar, the alerts sound each time the bar changes color. (I have adjusted the inputs to cause multiple changes per bar)

Ok
Thanks a ton

Hello stockwolf,

You can do this two ways. The easiest thing to do is add setComputOnClose() to your preMain() function. This will force the EFS to only execute once per bar after each bar closes.

The other option is to use getBarState() and put your code inside a check for BARSTATE_NEWBAR, which only occurs once at the open of a bar. This will essentially do the same thing as setComputeOnClose(). However, you will also need to change the conditional statements to look at the values from the previous bar. Your code would look something like below.

if (getBarState() == BARSTATE_NEWBAR) {
    var BAMMSValue_1 = BAMMSValue;  // BAMMSValue needs to be global
    var vSMA_1 = vSMA;  // vSMA also needs to be global
    ...
    ...
    
    else if(BAMMSValue_1 > vSMA_1) {  // create _1 variables that store the previous bar's values.
        setPriceBarColor(Color.green);
        setBarThickness(2);
        setBarFgColor(Color.green);
        if (bLong == false) {
            Alert.playSound("C:\Documents and Settings\My Music\outthere.wav");
            bLong = true;    // global var
            bShort = false;  // global var
        }
    } else if(BAMMSValue_1 < vSMA_1) {
        setPriceBarColor(Color.red);
        setBarThickness(2);
        setBarFgColor(Color.red);
        if (bShort == false) {
            Alert.playSound("C:\Documents and Settings\My Music\hello.wav");
            bShort = true;
            bLong = false;
        }
    }
} 

This new modification may also make the global boolean variables, bLong and bShort unnecessaray.
