Can any one write an AFL for Range Action Verification Index.
Following is the Metacode sample :

Thanks

use this:

/*
RAVI stands for Range Action Verification Index.
This is a technical indicator that also helps to recognize trending markets, for the same purpose of helping trend following systems
to avoid entering whipsaw trades in sideways markets. The RAVI index is a moving average crossover system itself?it uses a 7-Day fast
average AND a 65-Day slow average. The RAVI index value is defined as the absolute value of the percentage difference between the 7
AND 65 Day averages. When a market is moving sideways, the two averages tend to have the same values, so the difference is small.
Conversely, when the market is trending, the fast average rapidly pulls away from the slow average, producing a larger difference
AND larger index value. Generally speaking, a RAVI value below 3 percent indicates sideways prices, AND above 3 percent, trending prices.
*/

x= MA(C,7)/C;
y= MA(C,65)/C;

z = x- y ;
z1 = z*100;
Plot(z1,"ravi",1,1);
Plot(-1,"",1,1);
Plot(1,"",1,1);
