If you want higher degrees of precision the indicator needs to be programmed to take advantage of FormatPriceMarkers().

public override string FormatPriceMarker(double price)
{
     // Formats price values to 4 decimal places
     return price.ToString("N4");
}

Thanks Josh...
So if the value I wish to adjust precision of is an indicator value being set as such:

Value.Set(KDRatio(Closes[Instrument1][0], Instrument2Close[0], Normalize)


How exactly would I treat this? Do I first pass Closes[Instrument1][0] and Instrument2Close[0] to "FormatPriceMarker", or do I just do something like:

Value.Set(FormatPriceMarker(KDRatio(Closes[Instrument1][0], Instrument2Close[0], Normalize))


Thanks
Shawn



public override string FormatPriceMarker(double price)
{
// Formats price values to 4 decimal places
return price.ToString("N4");


}

shawnh,

You don't need to pass anything into FormatPriceMarker(). All you do is override the method and all plots of that indicator will take advantage of the formatting you applied to the indicator.

[shawnh]

What do you mean by "override the method"? How do you do that?

[NinjaTrader_JoshP]

shawnh,

Just copy paste the code I have provided below and outside of OnBarUpdate() and then you should be fine. Notice how Initialize() and OnBarUpdate() are on the same "level". FormatPriceMarker() should be on the same level as them.

OK, thanks Josh.

I've posted an updated Ratio indicator in the Indicators section:

http://www.ninjatrader-support2.com/...d=1&linkid=288

Also, I've replaced the "Spread3.zip" file (3-instrument model indicator) in post #27 of this thread; it fixes a subtle synchronization problem, so anyone who is using the older version of that file should download the new version.

Ratio indicator

I downloaded your ratio indicator to see the code because I am a novice working on something similar, however when I tried to compile it in NT7 I got an error on lines 412, 384, and 404 that namespace name "grid category" could not be found. Any suggestions to get this to work?

[kdoren]

It compiles fine for me under NT7 B13 (and previous versions also). I can't explain why it's not working for you. Are you compiling under NT7 B13?

Update: I just compiled under B14 and it works fine there too.

Resolved

I got it to work- was sending it to compile in NT6.5 careless mistake great indicator though.

still searching

hi kevin, hi folks,
I´m still searching for such kind of ration indicators working with multiple instruments eg. cabe and euro - I already installed the correlation indicator which is great but even weightier is that I want to have displayed exact spread in points (difference) and percent.
can you (kevin) or anybody other assist me?
thanks!
