need simple ea based on filter extra indicator


hi,please create this simple EA based on filter extra indicator.this indicator does not repaint,not even the first bar(not even if the price goes against it) .
EA opens sell position when color change to red and closes it when color change to blue and right away openes a buy position and closes it when red and so on... ea should have the feature to change the lenght of the indicator and lots(I manually now use it on daily chart with lenght 2).Other features you may want to add. thank you
