Hi,

there is a really big bug in Ninja:

I did the following:

1. Open a 3 Range chart of any instrument.
2. Put this indicator on your chart
(It's just:

if ( Close[0] == Open[0] )
BarColor = Color.Yellow;

)

3. Tell me why not every candle were the Close=Open becomes colored yellow ???

Here a screenshot:

Here a screenshot:

It is double.Epsilon issue.

You can try replacing your condition like this:

if ( Math.Abs(Close[0] - Open[0]) < TickSize * 0.5 )
BarColor = Color.Yellow;

Thanks for your response!

Now it looks better. That means every Open=Close bar
is colored yellow.
But also every bar were Open and Close only one tick away.

Please look at the screenshot.
What means double epsilon issue ?

I just edited my post (see below) to TickSize * 0.5

double.Epsilon is C# thing when dealing with double values - you have to be careful when comparing them.

Thank you so much!!!

I have to clarify:

IT'S NOT A NINJA TRADER BUG.
-only a programming issue

NINJA TRADER IS THE BEST TRADING PLATFORM EVER !!!
