Help modifying TMA centered bands indicator

Carl Schreiber 2016.11.30 09:14 #1

Sometimes the chart isn't painted correctly so that a painted break wasn't a break by the prices - if they are very close to each other and the scale of the chart is extreme.

Check the prices with the debugger at those points.

Hello,

I am attempting to modify a TMA centered indicator and could use some help. As the indicator stands now it plots points where price breaches either of the bands. The logic I am attempting to implement is fairly simple: If two consecutive breaches (the teal dots in the picture) of the upper band occur while the most recent breach is equal to or lower than the price of the previous breach a 'Sell" signal is generated. If two consecutive breaches of the lower band occur while the most recent breach is equal to or higher than the price of the previous breach a 'Buy' signal is generated.

I have attached a picture to show that the yellow arrows are generated correctly, however the most recent arrow is not and I am not sure why it is occurring. It will quickly correct itself and disappear but I am not sure why it is being drawn in the first place. I am assuming it has to do with assigning the past breach time to the current breach time but again, I am not sure. I imagine there is a better way of doing this but I am currently unaware of how to do that. I am not particularly good at programming, I know just enough to make a mess of things. I am hoping someone is able to help me correct this problem or direct me to a better way of doing it.

The portion of the code that plots the points is here:

for(i = limit; i >= 0; i--)
   {
      int      shift1 = iBarShift(NULL,timeFrame,Time[i]);
      datetime time1  = iTime    (NULL,timeFrame,shift1);

         tmBuffer[i] = iCustom(NULL,timeFrame,IndicatorFileName,"calculateTma",HalfLength,Price,BandsDeviations,0,shift1);
         upBuffer[i] = iCustom(NULL,timeFrame,IndicatorFileName,"calculateTma",HalfLength,Price,BandsDeviations,1,shift1);
         dnBuffer[i] = iCustom(NULL,timeFrame,IndicatorFileName,"calculateTma",HalfLength,Price,BandsDeviations,2,shift1);

         upArrow[i] = EMPTY_VALUE;
         dnArrow[i] = EMPTY_VALUE;
         upDot[i] = EMPTY_VALUE;
         dnDot[i] = EMPTY_VALUE;


               if (Close[i+1] > upBuffer[i+1] && Close[i+1] > Open[i+1] && Close[i] < Open[i]){

               pastUpperBreachTime = currentUpperBreachTime;
               currentUpperBreachTime = Time[i];
               upperBreachShift = iBarShift(NULL,0,pastUpperBreachTime);
               lowerBreachShift = iBarShift(NULL,0,currentLowerBreachTime);
               previousUpperBreachClose = Close[upperBreachShift];
               currentUpperBreachClose = Close[i];
               upDot[i] = High[i]+iATR(NULL,0,20,i);

                  if((upperBreachShift < lowerBreachShift) && (currentUpperBreachClose < previousUpperBreachClose)){
                  upArrow[i] = High[i]+(iATR(NULL,0,20,i) * 2.75);
                  }
               }
               if (Close[i+1] < dnBuffer[i+1] && Close[i+1] < Open[i+1] && Close[i] > Open[i]){

               pastLowerBreachTime = currentLowerBreachTime;
               currentLowerBreachTime = Time[i];
               lowerBreachShift = iBarShift(NULL,0,pastLowerBreachTime);
               upperBreachShift = iBarShift(NULL,0,currentUpperBreachTime);
               previousLowerBreachClose = Close[lowerBreachShift];
               currentLowerBreachClose = Close[i];
               dnDot[i] = Low[i]-iATR(NULL,0,20,i);

                  if((lowerBreachShift < upperBreachShift) && (currentLowerBreachClose > previousLowerBreachClose)){
                  dnArrow[i] = Low[i]-(iATR(NULL,0,20,i) * 2.75);
               }
               }

Thanks for any help or suggestions!

Centered TMA is recalculating/repainting.

As I have tried to explain in numerous occasions - using recalculating indicators in any form of "signaling" mode is dangerous and it does not lead to results that people expect. I would like recommend to all using centered TMA to read this book : https://www.amazon.com/Channels-Cycles-Tribute-J-Hurst/dp/0934380503 in order to get a clear picture how centered TMA (and bands) should be used

Thanks for the response and advice, I'll be sure to check out the book. I know you have to be tired of constantly explaining your indicators. Sorry about that.
