formula

[pbeno]

hello,

can anyone inform me of why I continually receive a syntax error pertaining to the following statement:

var fullbuy=(var nclose-var nhigh)/var nhigh);

Please note, I have tried eliminating the "var" in front of "full buy" and adding an additional "=".

Thank you in advance.

PB

usually var is used to declare variables before -- function main()
ex. var fullbuy = 0;
after that, just use the variable

I think your main problem is any 'var' on the right side of =
also you have 2 right ')', 1 left

try
fullbuy=((nclose- nhigh)/ nhigh); // but declare variables first

Thx DZ for your input. It unfortunately did not fix my problem but I appreciate your input.

Hello PB,

You may need to post the actual code you are working with so we can see what the specific problem may be.

In the mean time, try this,

var fullbuy = ( close(0) - high(0) ) / high(0) ;

or this,

var nclose = close(0);
var nhigh = high(0);

var fullbuy = ( nclose - nhigh) / nhigh;

Response with code

Hello Jason,

The following is the code to date. I am aiming to develop a code that tracks my current position whether long/short and determine whether the subsequent moves, high or low, from that position is greater than 1.0%. Thx again.

function preMain() {
setPriceStudy(true)
}


function main() {

nSignalHigh=high
nSignalLow=low
var3=.01;
FullBuy=((close-nSignalHigh)/nSignalHigh>=var3);
FullSell=((close-nSignalLow)/nSignalLow<=var3);

if (Strategy.isInTrade()) {
if ((FullBuy==true) && (Strategy.isShort())) {
Strategy.doCover("ExitShort", Strategy.MARKET,Strategy.NEXTBAR);
Strategy.doLong("RevLong",Strategy.MARKET,Strategy .NEXTBAR);
Alert ("Full Buy");
debugPrintln("Full Buy");
}
if ((FullSell==true)&&(Strategy.isLong()==true)) {
Strategy.doSell("ExitLong",Strategy.MARKET,Strateg y.NEXTBAR);
Strategy.doShort("RevShort",Strategy.MARKET,Strate gy.NEXTBAR);
Alert("Full Sell");
debugPrintln("Full Sell");
}
if ((FullBuy==true)&&(Strategy.isLong())) {
Strategy.doLong("RevLong",Strategy.MARKET,Strategy .NEXTBAR);
Alert("InterimBuy");
debugPrintln("InterimBuy");
}
if ((FullSell=true)&&(Strategy.isShort())) {
Strategy.doShort("RevShort",Strategy.MARKET,Strate gy.NEXTBAR);
Alert("InterimShort");
debugPrintln("InterimShort");
}
}
}

Hello PB,

The code you have posted has many syntax and logic errors. Rather than go through each one for you here I recommend that you try to learn more about the basics of EFS and programming in JavaScript.

To learn more about general programming in JavaScript (the foundation for EFS), please start with our JavaScript for EFS video series.

Then move on to our Beginner Tutorials to learn about the specifics of EFS formula development. To learn more about creating back testing formulas, there are also a couple tutorials dedicated to this process, which can also be found at the link above.
