To express the number of points, you must divide by Point. This seems to be a so-called predefined variable, which is the size of a single point. Oh, no, no, that's not it. Let's say you have a certain price value, let's say 1.2244. If you want to add 5 points to the price, you have to write it as 1.2244+(5*Point), it will be 1.2249. Do you understand?


It all makes sense now, thank you very much!

Can you tell me if there is already an indicator that calculates the index (basket) of currencies as a percentage?
for example from
Euro 37.4
Japanese yen 9.4
Pound sterling 11.3
U.S. dollar 41.9
 

Hi folks, could you please tell a newbie how the "mikahekin" indicator changes the displayed buffer? And how do I get the "Alert" function to shout out when the trend is changing?

P.S. The indicator is below.

Files:
mikahekinv1.0_.mq4  5 kb
 

Tell me, is it possible to crack a file with the extension ex4, which is on the password. And what else can be done besides the password written in the tutorial Kovalev, so that the expert is not hacked (if possible, of course) ?

Thank you.

Let them break in. It does not matter. No Expert Advisor will change the market, and everyone in the market cannot make money, it is not possible.

you can.
 

Hello, Professionals! Please advise me, I've been testing the Moving Average Expert Advisor, but after the weekend the tester gives error 131 wrong volumes... but before that everything was fine... I've been testing with a platform from MetaQuotes Software Corp.

 
Zhunko:

This script works for me:

This expert works strangely. You could say it doesn't work. It switches the TF on itself only up to M5.

I'll wait for the real ticks. I do not understand how the problem appeared. Something has changed in the new builds of MT4.

I have messed up with Expert Advisor code. The looped EA will switch the TF by itself, but the code is too cumbersome.

It could be simpler. This is for those who have access to autonomous update of the chart (it will work on Saturday and Sunday):

#include <ServicesMT4.mqh>
int g_hwndChart = NULL;
int g_nCounter = 0;

void init()
 {
  g_hwndChart = WindowHandle(Symbol(), Period()); // Получаем системный дескриптор графика.
  if (UninitializeReason() == 0) ServiceRefreshChart(g_hwndChart, 2000); // Запускаем обновление графика каждые 2 секунды.
 }

void deinit()
 {
  if (UninitializeReason() == REASON_REMOVE || UninitializeReason() == REASON_CHARTCLOSE)
   {
    ServiceStopRefreshChart(g_hwndChart); // Останавливаем обновление.
   }
 }

void start()
 {
  ServiceSetTimeframeByNumber(g_hwndChart, g_nCounter % 9);
  g_nCounter++;
  Sleep(2000);
 }
This is for those who can't access offline chart updates: 
#include <ServicesMT4.mqh>
int g_hwndChart = NULL;
int g_nCounter = 0;

void init()
 {
  g_hwndChart = WindowHandle(Symbol(), Period()); // Получаем системный дескриптор графика.
 }

void start()
 {
  ServiceSetTimeframeByNumber(g_hwndChart, g_nCounter % 9);
  g_nCounter++;
  Sleep(2000);
 }

Or like this:

#include <ServicesMT4.mqh>
int g_nCounter = 0;

void start()
 {
  ServiceSetTimeframeByNumber(WindowHandle(Symbol(),Period()), g_nCounter % 9);
  g_nCounter++;
  Sleep(2000);
 }

Well, what do you think, Rustam? Has anyone here for the last 2 days shown the code of TF switching in Expert Advisor? You think you are a pro, but you couldn't figure it out. You couldn't see the error in a simple code. But you managed to praise someone else's development.
