I'm trying to solve a problem with the DtdOsc signal and find out why I got it wrong; There are other errors - MQL4 and MetaTrader 4

How to compute WPR value of an indicator buffer?

Saji · 2013-12-29T09:59:18.0000000Z

Hi, all: I want to calculate the WPR value of a detrended price series. First, I use an indicator buffer to store the detrended price series. But to simplify the question, I directly transfer the raw prices to the buffer. Export the so called "detrended price series" into the chart, we can see it's exactly the same as the raw prices.(see below) Now, the question is how can I use an effective way to calculate the WPR value of the detrended price series. Because there is no "OnArray" function to use, I guess the only way is to write "for" code to directly calculate the value. Below is the code I use: //---- Oscillator of Detrended Signal Computing for (i= 0 ; i<limit; i++) { DtdValueMin[i] = 999999 ; DtdValueMax[i] = - 999999 ; for ( int k= 0 ; k<=Osc_Period; k++) { if (DtdValue[k] > DtdValueMax[i]) DtdValueMax[i] = DtdValue[k]; if (DtdValue[k] < DtdValueMin[i]) DtdValueMin[i] = DtdValue[k]; } DtdOsc[i] = 0.02 *((DtdValue[i]-DtdValueMin[i])/(DtdValueMax[i]-DtdValueMin[i])* 100 - 50 ); if (DtdOsc[i]> 0.9999 ) DtdOsc[i]= 0.9999 ; if (DtdOsc[i]<- 0.9999 ) DtdOsc[i]=- 0.9999 ; } return ( 0 ); } You can see that there is a "for" circle in another "for" circle, which is not a fast algorithm I think. And the result is odd....... Theoretically, the calculated result should be exactly the same as iWPR in the MT4. But the result is not the same, so there must be errors. And I can't find it, so if anyone had think about this question before, pls HELP! saji

if I remove the code of limitation to the DtdOsc value:

/*      if(DtdOsc[i]>0.9999)
         DtdOsc[i]=0.9999;
      if(DtdOsc[i]<-0.9999)
         DtdOsc[i]=-0.9999;*/

then I got the second signal in the last pics,which has exactly the same dynamics of the raw price data.

So I think there must be other errors, mostlikely in the computing of the local Max/Min value of DtdValue[].

You could just use iHighest() and iLowest() and then use these bar values with High[] and Low[]

You know that iHighest() just can be applied to the raw price series, which is not appliable to my "detrended prices" buffer.

int iHighest(

string symbol, int timeframe, int type, int count=WHOLE_ARRAY, int start=0)

It means the input series should be the raw prices, not certain buffer.

It seems that no one could solve this yet.....

Can anyone provide the original code of iCCIonArray() function in the MT4?

So I can refer to it, and find out my errors in the code.

Thanks!

Or maybe I can use the ArrayMaximum() instead....I'll find out

And you array is comprised of Close values . . .

DtdValue[i]=Close[i]

Man! I'm really tied of explaining again and again......

In this simplified version, i use a local mean of zero value to calculate the DtdValue[].......Again, to simplify the question!!!!

What if I use a Simple MA trendline as a local mean?

And will DtdValue[i] still equal to Close[i] again? No!!!!

The DtdValue[] will just be an indicator buffer, and its value will not equal to any existed price data!!!

So I have to calculate the WPR of an indicator buffer(again,not the raw price) by myself!

If you are tired, I suggest you to take some rest.
If you are not able to program it yourself, you can try to hire a programmer.

Do you normaly speak to people that way when you expect them to do something for you ? It makes me wonder what kind of people we deal with on here....
