[amibroker] Re: Vortex Indicator

["Richard" <richpach2@xxxxxxxxx>]

Hi "droskill",

I am a little confused by the rules as well. Sum(abs(....)..) will never go below 0 and you can see it if you plot VIP or VIM.
As the result, he rules do not generate any Buy or Sell signals.
Buy=Cross(VIP,1); seems to create some reasonable entries but this is not what the rules say.

Regards
Richard

While the formula for the indicator is listed in the magazine, I was wondering if anyone has written a code for turning this into a system and testing the validity of this indicator. The Tradestation and Nuroshell has code for an entry, exit and shorting strategies.
