How to get the last 3 point of ZigZag indicator?

New comment
 

How to get the tree last values of indicator Zig zag, last high or last low etc.

 

Try iCustom().

Seach backwards through the index and find the values.

 

//------------------------------------------------------------------------------------
// Nth ZIGZAG value
//------------------------------------------------------------------------------------
double getNthZIGZAGValue(string _SYMBOL, int _TIMEFRAME, bool UpperLower, int Nth)
{
double result = 0;
int i = 0;
int NthZIGZAG = 2*Nth + 1;
double ZIGZAG1 = 0;
double ZIGZAG2 = 0;

while(i < 1000 && NthZIGZAG > 0)
{
result = iCustom(_SYMBOL, _TIMEFRAME, "ZigZag", 12, 5, 3, 0, i);

i++;

if(result > 0)
{
ZIGZAG1 = ZIGZAG2;
ZIGZAG2 = result;
NthZIGZAG--;
continue;
}
}

if(UpperLower)
{
if(ZIGZAG1 > ZIGZAG2)
result = ZIGZAG1;
else
result = ZIGZAG2;
}
else
{
if(ZIGZAG1 > ZIGZAG2)
result = ZIGZAG2;
else
result = ZIGZAG1;
}

return (result);
}
//------------------------------------------------------------------------------------
// Nth ZIGZAG time
//------------------------------------------------------------------------------------
datetime getNthZIGZAGTime(string _SYMBOL, int _TIMEFRAME, bool UpperLower, int Nth)
{
double result = 0;
int i = 0;
int NthZIGZAG = 2*Nth + 1;
double ZIGZAG1 = 0;
double ZIGZAG2 = 0;
int ZIGZAG1Time = 0;
int ZIGZAG2Time = 0;

while(i < 1000 && NthZIGZAG > 0)
{
result = iCustom(_SYMBOL, _TIMEFRAME, "ZigZag", 12, 5, 3, 0, i);

i++;

if(result > 0)
{
ZIGZAG1 = ZIGZAG2;
ZIGZAG2 = result;
ZIGZAG1Time = ZIGZAG2Time;
ZIGZAG2Time = i - 1;
NthZIGZAG--;
continue;
}
}

if(UpperLower)
{
if(ZIGZAG1 > ZIGZAG2)
result = ZIGZAG1Time;
else
result = ZIGZAG2Time;
}
else
{

}

return(iTime(_SYMBOL, _TIMEFRAME, result));
}
