Alert when approaching High

[CAS1]

I am attempting to put together an EFS that will color the chart background when a stock is within .05 (or any other # desirded) of its day high. I would also like to have a sound play say every 5 seconds as long as it is within that range of the high. I would then do the same for the low side as well.

I have the following code as a start...i'm getting an error about calling the High:

var vLastAlert = -1;

function preMain(){
setPriceStudy(true);
setStudyTitle("High");

}

function main(){

var nearhigh = callFunction("gettodayOHLC.efs","High");

if (close() <=nearhigh -0.05)
onAction1()

return null;
}

function onAction1(){
setChartBG(Color.lime);

vLastAlert = 1;
}





If anyone has any ideas on how to complete this I would greatly appreciate it. I'm still searching the msg boards for answers as well.

Thanks,

cas

The enclosed code should do what you want

vLastAlert=-1;

function preMain(){
setPriceStudy(true);
setStudyTitle("High");
}

function main(){

var nearhigh = callFunction("/OHLC/getTodayOHLC.efs","main","High"); 
 
if (close() >=nearhigh -0.05){
onAction1();
}else{
setChartBG(Color.white);
}

return null;
}

function onAction1(){
setChartBG(Color.lime);
vLastAlert = 1;
} 

Also you may want to look at the Background.efs which is available here which may provide you with some further ideas.

Alex,

Thank you very much! that works great....then I got to thinking/cut/pasting..and realized that it would be good to have both the high/low side in a single EFS. The one I came up with below only colors the chart on the low side..not the high side....can you quickly see where my error is?

vLastAlert=-1;

function preMain(){
setPriceStudy(true);
setStudyTitle("NearHigh_low");
}

function main(){

var nearhigh = callFunction("/OHLC/getTodayOHLC_cas.efs","main","High");
var nearlow = callFunction ("/OHLC/getTodayOHLC_cas.efs","main","Low");

if (close() >=nearhigh -0.05)
onAction1();

if (close() <=nearlow +.05)
onAction2();


else{
setChartBG(Color.lightgrey);
}

return null;
}

function onAction1(){
setChartBG(Color.green);
vLastAlert = 1;
}
function onAction2(){
setChartBG(Color.red);
vLastAlert = 2;
}



Thank you again for all of the help!

The main reason the efs will not work is because you are using two callFunction() with getTodayOHLC.efs which is not set up for that.
Download and save to the OHLC folder the attached getTodayOHLC1.efs and substitute the efs name in your formula.
Once the above changes are implemented it should work (barring any syntax errors which I have not checked for)

Alex,

Thanks for the quick reply's.....I think i'm confused....since I am trying to get both the high and low of the day, I thought I needed to assign to a variable...hence my attempt at calling both...this is below is wher ei'm at....I get no errors....but no chart color either:

vLastAlert=-1;

function preMain(){
setPriceStudy(true);
setStudyTitle("NearHigh_low");
}

function main(){

var nearhigh = callFunction("/OHLC/gettodayohlc1.efs","main","High");
var nearlow = callFunction ("/OHLC/gettodayohlc1.efs","main","Low");

if (close() >=nearhigh -0.05)
onAction1();

if (close() <=nearlow +.05)
onAction2();


else{
setChartBG(Color.lightgrey);
}

return null;
}

function onAction1(){
setChartBG(Color.green);
vLastAlert = 1;
}
function onAction2(){
setChartBG(Color.red);
vLastAlert = 2;
}

As to making the two calls that was correct. It is the efs you were calling that cannot be used in that instance which is why I provided one that was modified to be used with multiple calls.
With regards to the efs it seems to be working (I just modified the nearlow value to +10 to trigger it with $INDU).

hmmm....yes, it does color on new lows...but in putting in charts at highs, I don't get results. I'm playing around with it still.....must be something very simple.

Thanks,

Change the conditions to the following
Alex

if (close() >=nearhigh -0.05){
onAction1();
}
else if (close() <=nearlow +0.05){
onAction2();
}
else{
setChartBG(Color.lightgrey);
} 

[CAS1]

Bingo! Thank you very much!

Alert - Near the High

Alex:
Is it possible to create an alert for this .efs instead of coloring the background or bar?

Harndog

The enclosed efs should do the following.
When the High (or Low) first crosses the pre-set threshold it should sound one ding and trigger an alert list. The alerts should reset once the High (or Low) of a bar crosses back under (or over) the threshold.
Alex

var nLastRawTime; 

function preMain(){
setPriceStudy(true);
setStudyTitle("NearHigh_low");

}

function main(){

var nearhigh = callFunction("/OHLC/gettodayohlc1.efs","main","High"); 
var nearlow = callFunction ("/OHLC/gettodayohlc1.efs","main","Low");

    if (getValue("rawtime",0) != nLastRawTime) { 
    
        if (high() >= nearhigh-0.05 && high(-1) < nearhigh-0.05){
            Alert.playSound("ding.wav");
            Alert.addToList(getSymbol(),"Near High",Color.black,Color.lime);
            nLastRawTime = getValue("rawtime",0);
        }
        if (low() <= nearlow+0.05 && low(-1) > nearlow+0.05){
            Alert.playSound("ding.wav");
            Alert.addToList(getSymbol(),"Near Low",Color.black,Color.red);
            nLastRawTime = getValue("rawtime",0);
        }
    }
    
return null;
}

Hello All,

Has anyone managed to get the script below to work? Each time I run it I get the following message even the file is located in the directory in which it is being called?


"Error Calling Function (main) in OHLC/gettodayohlc1.efs

Any assistance would be greatly appreciated.

Try using the attached version of getTodayOHLC1.efs and see if it returns the same error.

Alex,

Thanks for getting back to me. The attached efs no longer gives me an syntax errors, however its not showing any data on the chart at all.


Cheers

Alex,

What I meant to say was, "there are no syntax errors, however, its not alerting when a new high is approaching."

Cheers

Carlton
