EFS Calculate Intraday using prior days' extremes

[TBond]

I'm trying to write a few studies - the one below the current one I'm working on. Here is what I would like to accomplish (what I have so far only works using intraday bars - i.e., the prior 4 H-O etc is the prior 4 intraday bars)

I would like a study and alert that triggers on the following conditions:

1. is updated intraday on anytime timeframe chosen if today is day "0"
2. upside alert: today's high is greater than or equal to today's open plus the average of the prior four days' intraday highs - open e.g. today's high >= today's open plus average of ((High-Open)day"-1"+(High-Open)day"-2"+(High-Open)day"-3"+(High-Open)day"-4"
3. downside alert: today's low is less than or equal to today's open plus the average of the prior four days' intraday lows - open e.g. today's low <= today's open plus average of ((Low-Open)day"-1"+(Low-Open)day"-2"+(Low-Open)day"-3"+(Low-Open)day"-4"

On an intraday basis I want the calculation done using DAILY highs - opens and lows -opens for prior days and then add or subtract that to today's open. Therefore for instance on bonds if the calculations for the daily h-o and l-o for prior days is +7/32 and -7/32 then today for the entire day the upside alert would be equal to the open for the day at 0820 ET +7/32 or -7/32. only when those prices levels are broken on an intraday is the alert generated.

=======
function preMain() {
setPriceStudy(true);
setStudyTitle("Strategy");
}

function main() {
var avgh = 0, avgl = 0;
var vHL = high() - low();
var vVar = vHL * 0.25;
var vaddvar = vVar * 0.35;

for(i = -4; i < 0; i++){
avgh += high(i) - open(i);
avgl += low(i) - open(i);
}

avgh /= 4;
avgl /= 4;

if(high() >= open() + avgh){
Alert.playsound("Alert.wav");
Alert.addtolist(getsymbol(), "upside alert", Color.black, Color.green);

}
if(low() <= open() + avgl){
Alert.playSound("Alert.wav");
Alert.addToList(getSymbol(), "downside alert", Color.black, Color.green);

}


}

Thanks!
