Mladen made a range of experimental indicators that were pleasing to the eye, and those indicators were dubbed as the experimental "Fancy" & "Hollow" versions.
This is the Schaff Trend Cycle "Fancy" version which, just like the Stochastic "Fancy", can be used as a regular non-repainting Schaff Trend Cycle indicator with different visual options.
For the Stochastic "Fancy" version, you can find it here: Stochastic "Fancy" Hollow version for MT4.
