Indicators: Relative Vigor Index (RVI)

 

Relative Vigor Index (RVI):

The main point of Relative Vigor Index Indicator (RVI) is that on the bull market the closing price is, as a rule, higher, than the opening price.

I have been analyzing several different pairs using the RVI. I find using three RVI indicators of different values works very well. I have zero programing skills and find the web instruction very difficult to follow. Could someone create an EA or Indicator for me?
 

What about the SUM value: NUM = SUM (VALUE1, N). Does it mean that the value of VALUE1 should be added to the value of N, the period of the smoothing?

Is the period of smoothing the one we change in the extern double? Is it the same as extern int ExtRVIPeriod=...?

Also, why is 'CLOSE' not 'Close[]'? It gives me errors when I try to compile it.

In general, if I'm creating an EA using two lines of an indicator, should I include/call that particular indicator using the double iCustom or cut that indicator's formula manually and paste it into the EA I'm making?
