I am trying to create a ZigZag indicator and draw it on the chart using MQL5. However, I'm facing difficulties in getting the indicator to appear on the chart. Here's my code
void TrendLineCreator::TrendLineCreatorDrawer()
{
double ZigZagBufferHigh[];
double ZigZagBufferLow[];
double ZigZagHandler = iCustom(_Symbol, _Period, "Examples/ZigZag");
int ZigZagCountHigh = CopyBuffer(ZigZagHandler, 1, 0, 100, ZigZagBufferHigh);
int ZigZagCountLow = CopyBuffer(ZigZagHandler, 2, 0, 100, ZigZagBufferLow);
ArraySetAsSeries(ZigZagBufferLow,true);
string trendlineName ="ZigZag_";
datetime time1;
datetime time2;
for(int i = 1; i < ArraySize(ZigZagBufferLow)-2 ; i++)
{
if(ZigZagBufferLow[i] != ZigZagBufferLow[i+1])
{
if(iLow(_Symbol,_Period,i)!=ZigZagBufferLow[i])
{
time1 = iTime(_Symbol, _Period, i);
time2 = iTime(_Symbol, _Period, i+1);
trendlineName = "ZigZag_" + IntegerToString(i);
ObjectCreate(0, trendlineName, OBJ_TREND, 0, time1, ZigZagBufferLow[i], time2, ZigZagBufferLow[i+1]);
ObjectSetInteger(0, trendlineName, OBJPROP_STYLE, STYLE_SOLID);
ObjectSetInteger(0, trendlineName, OBJPROP_WIDTH, 3);
ObjectSetInteger(0, trendlineName, OBJPROP_COLOR, clrRed);
}
}
}
}

welcome.
I would check the
ZigZagBufferLow[i]
by adding a line to print out its content:
for(int i = 1; i < ArraySize(ZigZagBufferLow)-2 ; i++)
Print("ZigZagBufferLow[i]: ",ZigZagBufferLow[i]);
{
if(ZigZagBufferLow[i] != ZigZagBufferLow[i+1])
{...
You could print the other element
ZigZagBufferLow[i+1]
as well.
Hope this helps.
