How I can get "clean" buy/sell signals in AFL?

[rasnitsyn@xxxx]

Hello!

Is it possible to get "clean", i.e. filter out repetative buy/sell 
signals in AFL?

The following is an example of what I'm trying to achieve:

buy : { 1, 0, 0, 0, 0, 0, 1, 1, 0 }
sell: { 0, 0, 1, 0, 1, 1, 0, 0, 1 }

I need to get the following vectors:

realbuy: { 1, 0, 0, 0, 0, 0, 1, 0, 0}
realsell:{ 0, 0, 1, 0, 0, 0, 0, 0, 1}

Is it possible to od this in AFL?

Thanks in advance,
Dima.
