Helo,

Is it possible to drwa support and resistance arcs for a security in wealth lab pro.

Sure, anything is possible. You can draw just about anything in code using functions in the Cosmetic Chart category of the QuickRef (F11).

If you're looking for a manual drawing tool, check out the FIB arcs tool in the right border of the app.

Thanks Cone.

I actually meant drawing support & resistance arcs like the one shown in the below website

If you look at the S&P 500 chart in the above link, you will see the support & resistance arcs. Is it possible to draw these either computationally or manually in wealth lab pro?

Thanks again.

One night a few years ago I played around with curve fitting in Version 4 solving for the coefficients of a quadratic (3 points). It's not very useful since you need to identify and plug in the 3 {x,y} points by hand, and using a bit of trial and error to get the right curve. The result -



Let's try to find and apply something more useful like an optimized curve fitting algorithm already available in C# in ALGLIB. In fact, we'll have to investigate the GPL license to see if it's feasible to pack that up as an extension for Wealth-Lab 5.

Hacked around a bit with ALGLIB's Cubic Spline method. Here it is, somewhat automated, connecting 5% peaks -



I think we need something more of an monotonic interpolating solution that doesn't necessarily hit all the input points exactly to really get the smooth curve or "arcs". I'll do some more digging as time permits.
