Questions from Beginners MQL5 MT5 MetaTrader 5 - page 1297

[VVT]

Good afternoon, can you tell me if the swap is calculated in money or in points? How do I get the swap value in points?

PositionGetDouble(POSITION_SWAP) ???

[Oleg Kolesov]

Hello, can you help me? Question. I am trending by the angle in my EA. When a new bar comes, it sees one, butignores the secondanchor point.

#include <ChartObjects\ChartObjectsLines.mqh>   // Класс ChartObjectsLines   
CChartObjectTrendByAngle myline1;   // Объект класса ChartObjectsLines
// координаты опорных точек трендовых
   datetime time1=iTime(_Symbol,_Period,1);
   datetime time2=iTime(_Symbol,_Period,Period2);
   double price1=iClose(_Symbol,_Period,1);
   double price2=iClose(_Symbol,_Period,Period2);
    myline1.Create(0,"STrend",0,time1,price1,time2,price2);
    myline1.Create(0,"STrend",0,time2,price2,time1,price1);

Why do you create the same object twice? But you don't initialize the line angle (CChartObjectTrendByAngle::Angle method) ?

[Oleg Kolesov]

Vladimir, the last one is redundant. I wanted to show (if you swap the variables), does it draw the trend lines by one point only?

[Oleg Kolesov]

Vladimir angle(Get) property, you need to get. myangle1.Angle(); // Object angle value

[Oleg Kolesov]

double CChartObjectTrendByAngle::Angle(void) const?

[Oleg Kolesov]

ChartRedraw (0); doesn't work! Does it draw one point at a time?

Read the reference - where did you get the idea of one or two dots?

Create	Creates "Trend Lineby Angle"graphical object
Properties
Angle	Get/set "Angle" property

Thank you Vladimir. I'll give it a try.
