You are confusing EasyLanguage with the TA-script that you posted. The original indicator was written in EL and could be found if you search a little harder. eg, this is not EL: Code: (- File Name: Trend for All Markets -) var var FastLen, MMLen, SlowLen, Length, StDv, Average1, Average2, Smooth, i: integer; FastLen, MMLen, SlowLen, Length, StDv, Average1, Average2, Smooth, i: integer; xAvg1, bbMacd, xAvg21, xAvg22, xAvg23, xAvg31, xAvg32, xAvg33: TSeries; xAvg1, bbMacd, xAvg21, xAvg22, xAvg23, xAvg31, xAvg32, xAvg33: TSeries; sDev, upperBand, lowerBand, t3Trnd, t3TrndSmth: TSeries; sDev, upper band, lower band, t3Trnd, t3TrndSmth: TSeries; begin beginning FastLen := 12; FastLen: = 12; MMLen := 34; MMLen: = 34; SlowLen := 26; SlowLen: = 26; Length := 10; Length: = 10; StDv := 1; StDv: = 1; Average1 := 32; Average1: = 32; Average2 := 5; Average2: = 5; Smooth := 5; Smooth: = 5;
