As I already wrote in another e-mail sent directly to AmiBroker uses
additional 3-bar smoothing for Stochastic Slow. The smoothing is so called
Wilders-smoothing very similar to exponential but not the same.

I am glad to hear that.

I think that this is the most important thing in AmiBroker -
that you can adopt it to match your needs. I am sure that you find
AmiBroker the most configurable program available.
For example Metastock has similar formula language but lacks
extensive automation provided by AmiBroker thru JScript, lacks ability to
perform searches on multiple stocks at once, lacks filtering by
groups/industries/sectors/markets and so on.
