Help converting mql4 to mql5

New comment
 

Hello I am new to mql5 and I realize that I am having a hard time converting my indicators written in mql4 to mql5 because I lack a point of reference.

My indicators are similiar to the one Rosh wrote here: https://www.mql5.com/en/code/7072

Can someone show me what this sample code would look like in mql5.

What happens to the 'shift': i?

does it go away and is it handled by some other variable, and if so how?

DIPlus = iADX(NULL, 0, per, PriceType, MODE_PLUSDI, i);

And what about the MODE_PLUSDI too? The modes no longer exist.


If someone could convert this old format to MQL5, it would explain a lot about the new structure by providing a one to one example for us all.
Thanks for any replies

int hIADX;
double adxMain[];
double adxPlus[];
double adxMinus[];

hIADX = iADX( symbol, timeframe, adx_period );
ArraySetAsSeries( adxMain, true );
ArraySetAsSeries( adxPlus, true );
ArraySetAsSeries( adxMinus, true );

CopyBuffer( hIADX, 0, shift, 1, adxMain );
CopyBuffer( hIADX, 1, shift, 1, adxPlus );
CopyBuffer( hIADX, 2, shift, 1, adxMinus );

Print( "iAdx values at ", shift, " are ", adxMain[0], ",", adxPlus[0], ",", AdxMinus[0] );

for(i = limit; i >= 0; i--)
     {
       DIPlus = iADX(NULL, 0, per, PriceType, MODE_PLUSDI, i);
       DIMinus = iADX(NULL, 0, per, PriceType, MODE_MINUSDI, i);
       ADX = iADX(NULL, 0, per, PriceType, MODE_MAIN, i);
       DIPlus1 = iADX(NULL, 0, per, PriceType, MODE_PLUSDI, i + 1);
       DIMinus1 = iADX(NULL, 0, per, PriceType, MODE_MINUSDI, i + 1);
       ADX1 = iADX(NULL, 0, per, PriceType, MODE_MAIN, i + 1);
       //----
       DIPlusLead[i] = 2*DIPlus + (alpha1 - 2) * DIPlus1 + 
                       (1 - alpha1) * DIPlusLead[i+1];

Thank you for the reply fireflies, but there is one part that still eludes me. How do you avoid getting an array out of bounds error if I were to increment the DIPlusLead by one...DIPlusLead[i+1]?

Declare the array size as big as needed

// define MAXDI at least as big as i+1

double DIPlusLead[MAXDI];


 
nice job
