formatPriceNumber()

[dloomis]

I was suggesting you calc the len of the fractional part of the price to determine the number of digits past the decimal point.

ok but that won't work as in the example I gave, e.g. price of 32 where symbol is displayed with 2 decimal places. I need to calculate the number of displayed decimal places for the symbol

Hi bpschoch,

Have you tried using typeof() to determine if it is a data type issue? Short of anything more substantive, I am tapped out. I believe Murphy is probably in cahoots with Peter Cottontail on this one. ;~) Hope everything works out.

Cheers!

e.g. price of 32

I thought of that too, however if you use the suggestion I made you will have to keep track of the max number returned, that way if the security trades at 32, then 32.1 then 32.34 then only trades with a max of 2 decimals, you would quickly realize the number of decimals was 2.

I think the thing to do is to wait till someone from esignal can chime in. These calculations are done at initialization so I only get 1 price. In the end formatPriceNumber should be working and consistently, perhaps there is something wrong with the install that isn't working. Wel''l see what they say.

Hello Bernie,

I've been testing the following code and haven't been able to reproduce a zero length string for fp.

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

}

 
function main() {
    var nState = getBarState();
    var sym = getSymbol();
    
    if (nState == BARSTATE_ALLBARS) {
        debugClear();
        var p = close();
        var fp = formatPriceNumber(p);
        var intp = p.toFixed(0);
        var dec = fp.length - intp.length; // calculates number of dec pts in sym
        if (fp.indexOf(".") >= 0) dec -= 1;
        
        debugPrintln("dec: " + dec);
        debugPrintln("intp: " + intp + "  fp: " + fp + "  p: " + p);
    }
    
    return;
} 

The only thing I can think of codewise is that p is not getting set to a valid value before passing it to formatPriceNumber(). I would suggest applying some validation to p before allowing the script to continue.

Try something like if (isNaN(p) || p <= 0 || p == null) return;

Jason, I have an idea of what may be happening and it's a guess on how charting works. The other system (which doesn't work) is earl's who doesn't have interday stock but gets daily data for stocks (remember this works on my system ok). I suspect that formatPriceNumber uses a 'dictionary' that has data on how to format the symbol and that because he doesn't have intraday data, that dictionary is not loaded and therefore formatPriceNumber doesn't know how to format and then returns null. If that's the case then that dictionary should still be loaded

Hello Bernie,

So Earl is running this on Daily intervals only? I think you're on to something. I'll find out if this is supposed to work with EOD subscriptions.

[eSignal_JasonK]

Hello Bernie,

Your suspicion was pretty close. According to our development team, the formatPriceNumber() function does use some information sent with a quote record that may not be available in EOD versions. They are looking into it.

[bpschoch]

Yes I was able to duplicate it with the German Dax AX #F-DT which I don't subscribe to but do get a daily price and it fails there on my system also, so that's it.
