Strange Problem or eSignal Bugs?

[spin0]

I've been troubleshooting this peice of codes for a couple days and I still don't understand whether this is a bug from eSignal EFS or not.

Basically I have variable gsYourPosition = "NEUTRAL".
In main(), I use Alert.eMail(..,gsYourPosition,..) and I get all the time gsYourPosition = "SHORT"

Can somebody see what is wrong?
Have you encountered this type of problem?

Thanks.

Here is the code:
// This variable can take following values: LONG, SHORT, NEUTRAL
var gcLONG = "LONG";
var gcSHORT = "SHORT";
var gcNEUTRAL = "NEUTRAL";
var gsYourPosition = gcNEUTRAL;


//Declarations


function preMain() {

//main() will be executed only after the bar complete or close
setComputeOnClose();
setPriceStudy(true);
setStudyTitle("TEST 1.0");

}

function main() {

var sTrend = gcSHORT;

Alert.email("Before if... "+ gsYourPosition+ "Trend " +sTrend, close());
//Why gsYourPosition is equal to "SHORT" at this step??????


//If you haven't taken any position yet and the trend is DOWN (SHORT)
if (sTrend == gcSHORT) {
if (gsYourPosition == gcNEUTRAL) {
Alert.email("TEST 1.0 - Get in SHORT position now (SELL).", close());
gsYourPosition = gcSHORT;
}
}
}

It does not == short..

I ran your code and changed the Alert.email() line to debugPrintln().

This is the result....

Before if... NEUTRALTrend SHORT1015.5
Before if... SHORTTrend SHORT1015.25
Before if... SHORTTrend SHORT1015.25
Before if... SHORTTrend SHORT1015.5

You'll see that the value of your indicator is NEUTRAL when the code first runs. Then your code switches it to SHORT - and it stays short for the rest of the codes operation.

I think your code it fine. Alerts are typically not generated until the current bar. So, your code starts out with everything in NEUTRAL, but changes the variables to SHORT.

By the time your alert gets triggered - it's SHORT because your code is forcing it to be SHORT.

Hope this helps..

Strange Problem or eSignal Bugs?

Thank Brad.

So this means that I cannot count on Alert.eMail() function to do any alerts. Unless I have a way to make sure that Alert.eMail() is executed and completed before it goes to the next line of codes.

Hello spin0,

The Alert object only executes in real time, or when you are at the bar index of 0. When a formula is first applied to a chart, the formula processes the bar data starting with the oldest bar first. The Alert object will not generate alerts on historical data, otherwise you would get flooded with emails.

Alert.email only works in Real-Time

I've found an easy way to test the Alert.email() object....

Use Advanced SMTP Server (http://www.softstack.com/advsmtp.html). It is free for 30 days. It needs to be registered if used beyond, but is a local SMTP server that LOGS the last 1000 messages. Nice to see if eSignal made an attempt at sending a message. Set View|Alerts|(Email) Settings|SMTP Hosts to localhost to use it. The softstack.com guys have a Free SMTP Server too, but I found that one doesn't have a message sent log, bummer.

I've found that eSignal only sends Alert email when the Tools|EFS|Settings|'Make all formulas compute on close' is NOT checked. Repeat: NOT CHECKED. It only works in Real-Time, ie. Tick-by-Tick.

One of the easiest ways to test the Alert object is to enter an Alert.playSound() into the function main() {} code and see if it plays.

Now I just have to figure out how to have my code check the last COMPLETED bar's close(), since the above doesn't work and I am trying to check the bar's close(), not the high()/low().

I went through a bit of pain to figure this out, hope it helps someone else.

good job

The conditional below is a check for a new bar

if (getBarState() == BARSTATE_NEWBAR){
//this is true at the beginning of a new bar

}

Do you understand that main() is processed every tick? and the above if statement is true at the beginning of a new bar.

Another way is to use the setComputeOnClose(); statement in preMain().

Hello tedsmith,

To get the last completed bar's close in real time, check for the bar state, BARSTATE_NEWBAR, and then reference close(-1).

if (getBarState() == BARSTATE_NEWBAR) {
    var vPrevClose = close(-1);
}

Wow, I'm impressed with all the responses!
Thanks all!
