SDPOS = Sum of Up Deviations Over Minor Period (CL - MA)
 SDNEG = Sum of Down Deviations Over Minor Period (MA - CL)

Is this formula above what your pcf represents?  I get numbers returned that are seem too high.  Thanks for your assistance in advance.

Don

Not scientific but I used half a dozen symbols as the test one and all came back 85 to 100.  I used ones I would consider in less strength of an uptrend than what I comprehend the number should be.  Let me do a little more research and get back to this.  Thx.

inputs:
 AvgLength( 60 ),
 DevCalcLength( 30 ) ;
variables:
 Avg( 0 ),
 SDPlus( 0 ),
 SDMinus( 0 ),
 Dev( 0 ),
 Offset( 0 ),
 TII( 0 ) ;


Avg = Average( Close, AvgLength ) ;
SDPlus = 0 ;
SDMinus = 0 ;

for Offset = 0 to DevCalcLength - 1
 begin
 Dev = Close[Offset] - Avg ;
 if Dev > 0 then
  SDPlus = SDPlus + Dev
 else
  SDMinus = SDMinus - Dev ;
 end ;


TII = SDPlus / ( SDPlus + SDMinus ) * 100 ;

Plot1(TII,"TrendInten");

=============================================

Dont know if this helps but its TradeStaton Code for the indicator.


Thanks
