about Fibonacci Arcs .......these arcs meeting the trendline at Fibonacci levels of 38.2%, 50%, and 61.8%.
How is it be drawn? X-diff on Xaxes and y-diff on Yaxes and trendline length?
another ,what is "scale object property"?
Ellipse is determined with 2 lines - big radius and small radius.
2 points determine big radius (or rather double radius from center to one point and from center to another point ie diameter line). Big line is measured as x-axis in time units.
Small line is measured as y-axis in points.
Scale is the relation between big line time units and small line price units.
Set your chart for fixed 1:1 scale. It means 1 logical time unit contains as much physical pixels as 1 logical price unit. If you set ellipse scale as 1.0, then you get a regular circle
Setting 1:1 is nice...
In future, consider permitting user to specify X:1
1:1 can be useless on some instruments except in smallest timeframe.
Maybe you can help me with formulas for radius? depending from scale?
Im looking for 2 coardinates to use OBJ_ELLIPSE for Arc. insted of OBJ_FIBOARC.
