Nesting of MA and TEMA

[riofenix]

Nesting of MQL5 handles as iMA and iTEMA is not possible. I would need the Triple Exponential Moving Average of a Moving Average e.g.:

      int PRICE_GD_OPEN = iMA(_Symbol,PERIOD_CURRENT,10,0,MODE_SMA,PRICE_OPEN);
      double GD = iTEMA(_Symbol, PERIOD_CURRENT,4,0, PRICE_GD_OPEN);

How can I realize this?

int PRICE_GD_OPEN = iMA(_Symbol, PERIOD_CURRENT, 10, 0, MODE_SMA, PRICE_OPEN);
int GD = iTEMA(_Symbol, PERIOD_CURRENT, 4, 0, PRICE_GD_OPEN);
:
:
CopyBuffer(GD, 0, 0, rates_total, TEMA_Buffer);

Thank you. Still I do not know how to make it run.

int PRICE_GD_OPEN = iMA(_Symbol, PERIOD_CURRENT, 10, 0, MODE_SMA, PRICE_OPEN);
int GD = iTEMA(_Symbol, PERIOD_CURRENT, 4, 0, PRICE_GD_OPEN);

Both are handles. But

PRICE_GD_OPEN

in the iTEMA handle function as the last value should be entered as double value. But this double value is available only after CopyBuffer in OnTick and not yet in OnInit operation.

Entering

CopyBuffer(GD, 0, 0, rates_total, TEMA_Buffer);

adapted as

CopyBuffer(GD_handle, 0, 0, 100, GD);

only shows errors:

I feel unable to bring the routines in a right order:

double  GD[];  
int     GD_handle;          // handle of the indicator iTEMA

double  PRICE_GD_OPEN[];  
int     PRICE_GD_OPEN_handle;          // handle of the indicator iMA

int OnInit
{
  PRICE_GD_OPEN = iMA(_Symbol, PERIOD_CURRENT, 10, 0, MODE_SMA, PRICE_OPEN);
  GD_handle = iTEMA(_Symbol, PERIOD_CURRENT, 4, 0, PRICE_GD_OPEN[]);
}
  
void OnTick()
  { 


   CopyBuffer(GD_handle, 0, 0, 100,GD);
   
   CopyBuffer(PRICE_GD_OPEN_handle,0,0,100,PRICE_GD_OPEN);
   ArraySetAsSeries(PRICE_GD_OPEN,true); 

Can you help please?

iTEMA

The function returns the handle of the Triple Exponential Moving Average indicator. It has only one buffer.

int  iTEMA(    string                          symbol,               // symbol name    ENUM_TIMEFRAMES      period,               // period    int                              ma_period,         // averaging period    int                              ma_shift,            // horizontal shift of indicator    ENUM_APPLIED_PRICE  applied_price     // type of price or handle    );

applied_price

[in]  The price used. Can be any of the price constants ENUM_APPLIED_PRICE or a handle of another indicator.

What double value are you talking about?

The applied price or another indicator handle value will be entered here.

double  GD[];  
int     GD_handle;          // handle of the indicator iTEMA

//double  PRICE_GD_OPEN[];  
int     PRICE_GD_OPEN_handle;          // handle of the indicator iMA

int OnInit
{
  PRICE_GD_OPEN_handle = iMA(_Symbol, PERIOD_CURRENT, 10, 0, MODE_SMA, PRICE_OPEN);
  GD_handle = iTEMA(_Symbol, PERIOD_CURRENT, 4, 0, PRICE_GD_OPEN_handle);
}
  
void OnTick()
  { 


   CopyBuffer(GD_handle, 0, 0, 100, GD);
   
   //CopyBuffer(PRICE_GD_OPEN_handle,0,0,100,PRICE_GD_OPEN);
   //ArraySetAsSeries(PRICE_GD_OPEN,true);

Thank you so much, I have been not aware about your outpointed details. It runs smoothly changing

int OnInit

to

void OnInit()

What does this change (substantially) ? I am not aware of the difference.

I also had copied the whole thing without realizing this.

Without the parentheses, it would not be recognized as a function and should result in an error.
