Simple Coding Help - No Promise.

Dear friend Mercedes,
i will have to first understand this Supertrend afl :pompus:
Sir,

I think below AFL would be helpful. TrendUp and TrendDown variables can be used in desired output. But not a tech sevy, so difficult for me to code.

Code:
_SECTION_BEGIN("Super Trend");
Factor=Param("Factor",4,1,10,0.1);
Pd=Param("ATR Periods",10,1,100,1);
Up=(H+L)/2+(Factor*ATR(Pd));
Dn=(H+L)/2-(Factor*ATR(Pd));
iATR=ATR(Pd);
TrendUp=TrendDown=Null;
trend[0]=1;
changeOfTrend=0;
flag=flagh=0;

for (i = 1; i <BarCount-1; i++) {

      TrendUp[i] = Null;TrendDown[i] = Null; trend[i]=1;
      if (Close[i]>Up[i-1]) {
         trend[i]=1;
         if (trend[i-1] == -1) changeOfTrend = 1;
        }

      else if (Close[i]<Dn[i-1]) {
         trend[i]=-1;
         if (trend[i-1] == 1) changeOfTrend = 1;
      }

      else if (trend[i-1]==1) {
         trend[i]=1;
         changeOfTrend = 0;      
      }

      else if (trend[i-1]==-1) {
         trend[i]=-1;
         changeOfTrend = 0;
      }

      if (trend[i]<0 && trend[i-1]>0) {flag=1;}
      else {flag=0;}
      if (trend[i]>0 && trend[i-1]<0) {flagh=1;}
      else {flagh=0;}
      if (trend[i]>0 && Dn[i]<Dn[i-1]){Dn[i]=Dn[i-1];}
      if (trend[i]<0 && Up[i]>Up[i-1]){ Up[i]=Up[i-1];}
      if (flag==1){  Up[i]=(H[i]+L[i])/2+(Factor*iATR[i]);}
      if (flagh==1){ Dn[i]=(H[i]+L[i])/2-(Factor*iATR[i]);}
      if (trend[i]==1) {
            TrendUp[i]=Dn[i];
             if (changeOfTrend == 1) {
            TrendUp[i-1] = TrendDown[i-1];
            changeOfTrend = 0;
         }
      }

      else if (trend[i]==-1) {
         TrendDown[i]=Up[i];
         if (changeOfTrend == 1) {
            TrendDown[i-1] = TrendUp[i-1];
            changeOfTrend = 0;
         }
      }
   }

Plot(TrendUp,"TrendUp",colorGreen);
Plot(TrendDown,"TrendDown",colorRed);

_SECTION_END();

Dear friend cellclinic,
in the first pic, daily data is Empty, it is bcoz we r calculating moving average of 200 days, but there is not enough data , so it is shown as being Empty, n hence yellow dots on chart r not shown :happy:
yellow dots will only be shown on chart when current price is above the 200 sma of 15 mins timeframe n 200 sma of daily timeframe :happy:
change the periods in parameters to 10 or 15 n then yellow dots will b shown on chart :happy:
for scanning all stocks which r above the 200 sma of 15 mins timeframe n 200 sma of daily timeframe, just click on explore, n not on backtest :happy:
in this afl, i have not included the buy,sell,short n cover variables, without them u will get error in backtest :)
Hello Friend ...
