Ema(20)[0] = 0???

[shodson]

I'm coding an indicator using NT7 beta 19 and any indicators I use inside of it are returning 0.

            double f = EMA(20)[0];
            double s = EMA(50)[0];
            Print(f + "::" + s);

Prints several lines of this to my output window

0::0
0::0

0::0
0::0
0::0

0::0

What gives? The chart is not a bunch of bars with price = 0.

Hi shodson,

Stick this in there and see where it gets hung up.

Want to make sure you have enough bars.

Print(" CurrentBar = " + CurrentBar);

Still no good...

        protected override void OnBarUpdate()
        {
            if (CurrentBar <= 50)
                return;
            
            double f = EMA(20)[0];
            double s = EMA(50)[0];
            Print(CurrentBar + "==> " + f + "::" + s);
        }

And these are the results

51==> 0::0
52==> 0::0
53==> 0::0
54==> 0::0
55==> 0::0
56==> 0::0
57==> 0::0
58==> 0::0
...
2622==> 0::0
2623==> 0::0
2624==> 0::0
2625==> 0::0

Hi shodson,

You may have to create series first, then double.


EMA ema1 = EMA(Close, 20);

EMA ema2 = EMA(Close, 50);


double f = ema1[0] ;

double s = ema2[0] ;


Print(f + "::" + s);

Yeah, I tried that, that's the sort of thing I usually do, I just dumbed it down for the sake of posting a simple example to the forums. It still doesn't work even if I use an EMA object. If I specify the Close DataSeries I then get a runtime error:

Failed to call method 'Initialize' for indicator '______': 'BarsInProgress' property can't be accessed from within 'Initialize' method

Huh? I'm not even using BarsInProgress, it must think I'm trying to use multiple time frames.

Forget it, NT7 is a fail, again. Worse product beta I've ever seen.

works fine at my end. did i miss something

shodson,

If you actually posted your Initialize() code we could then tell you which parts are erroneous. Otherwise we can only see what you have in OnBarUpdate() and would have no way to help with your Initialize() method.

Hi Shodson,

Try using Zerolag MACD in the NT 6.5 download area.

http://www.ninjatrader.com/support/forum/local_links.php?s=&catid=1&keyid=&filter=&page=1&pp=15&sort=n

Just download, import, rename, and modify that indicator to your criteria.

Simple and Easy!!!
