It's going to be quicker for someone to modify the MQL4 code than to port the MQL5 code to MQL4 . . . probably.
- You could SEARCH for kama+mql4, get the indicator, and call iCustom.
int init(){ OnInitKama(); : } //+------------------------------------------------------------------+ //| Perry Kaufman's Adaptive Moving Average | //+------------------------------------------------------------------+ #define FASTEST_PERIOD 2 #define SLOWEST_PERIOD 99 #define LOOKBACK 10 double kama.High.value, kama.Low.value, fastestAlpha, slowestAlpha; int KamaCounted; void OnInitKama(){ KamaCounted = 0; fastestAlpha = 2. / (FASTEST_PERIOD + 1), slowestAlpha = 2. / (SLOWEST_PERIOD + 1); } void KamaUpdate(){ int iKama = Bars - 1 - KamaCounted; if (KamaCounted == 0){ iKama = Bars - 1 - LOOKBACK; kama.High.value = High[iKama]; kama.Low.value = Low[iKama]; } for(; iKama > 0; iKama--) KamaUpdatePrice(kama.High.value, High, iKama) KamaUpdatePrice(kama.Low.value, Low, iKama) } KamaCounted = Bars - 1; // Haven't done bar zero } void KamaUpdatePrice(double& value, double price[], int iBar){ int iLimit = iBar + LOOKBACK; double noise=0.00000001, signal = MathAbs( price[iLimit] - price[iBar] ); for (; iLimit > iBar; iLimit--){ noise += MathAbs( price[iLimit] - price[iLimit-1] ); } double alpha = signal/noise * (fastestAlpha - slowestAlpha) + slowestAlpha; kama.value += alpha * (price[iBar] - kama.value); } int start(){ KamaUpdate(); }

IF you see in MT5 you could find this indicator. I have attached it here.
There are similar ones in MT4. My problem is that I want to apply it to "Low" or "High" not only to close. You could do this in MT5, But because my broker is using MT4 I need to do it in this platform.
Can Anybody help?
I appreciate your time,
Regards,
