Fibonacci Circle Question

[Alfred]

In drawing a Fibonacci Circle...set to divide price & time separately....the circles do not seem to fall on the set-up line correctly...

Screen shot attached...

I can replicate this on my end. I'll be investigating further into the expected behavior with this setting enabled.

% X the square root of 2...

Patrick....Remembered later today, had looked at this once before....when divide/time separately is checked...multiply the percentage you want by the square root of 2 (1.4142).....thus 100% becomes 141.42....61.8% becomes 87.39....50% becomes 70.71 & so on.

I can't remember now exactly how I figured this out, but it seems to work OK....

Here is what one example looks like doing it this way...

Alfred, you're correct.

Here is the specific code from the Fibonacci tool which governs this. You can find this file in Documents > NinjaTrader 8 > bin > Custom > DrawingTools > @FibonacciTools.cs:

double xRange = Math.Abs(anchorEndPoint.X - anchorStartPoint.X);
double yRange = Math.Abs(anchorEndPoint.Y - anchorStartPoint.Y);
double mainLine	= Math.Sqrt(Math.Pow(xRange, 2) + Math.Pow(yRange, 2));
float levelFactor = (float)priceLevel.Value/100f;
float r = (float)(levelFactor * mainLine);
float xScale = (float)(levelFactor * xRange);
float yScale = (float)(levelFactor * yRange);
float ellipseRadiusX = IsTimePriceDividedSeparately ? xScale : r;
float ellipseRadiusY = IsTimePriceDividedSeparately ? yScale : r;

If you'd like, I can submit a feature request to change this default behavior.

Patrick...

Yes....revised default calc's of this tool would be good to have....!!

But isn't this a bug fix ...(not a feature request) ?? ....the tool is currently incorrect when dividing price/time separately....don't feature requests generally take more time than a bug fix...??....just curious....

....in any case...thanks...!!

The Fibonacci Circle is currently calculating as expected. We would not consider this a bug. Since you desire a change to the expected behavior, it would be considered a feature request.

I'll forward your suggestion to the Development Team. I'll provide a tracking number when I have one. EDIT: the tracking number is SFT-2619.
