Testing 'CopyTicks'

fxsaber, 2024.02.26 12:41 pm

If CopyTicks hangs for 60 seconds and returns error 4403, try to change the access point to the server. Even if the ping to it is less favourable.

In this sense, automatic selection of an access point by the terminal is dangerous.

Without launching this indicator (one instance for the whole Terminal), I no longer leave the combat Terminal, where work with CopyTicks is going on.

#include <fxsaber\MultiTester\MTTester.mqh> // https://www.mql5.com/ru/code/26132

#property indicator_chart_window
#property indicator_plots 0

input int inIntervalAlert = 5; // Error timeout interval (sec)
input int inMaxPoints = 5;     // Number of first server points

int OnCalculate( const int rates_total, const int prev_calculated, const int, const double &[] )
{
  static ulong StartTime = GetTickCount64();
  const ulong CurrTime = GetTickCount64();
  
  if (!prev_calculated)
  {
    Alert("Restarted!");
    
    StartTime = CurrTime;
  }
  else if (CheckCopyTicks() != ERR_HISTORY_TIMEOUT)
    StartTime = CurrTime;
  else if (CurrTime - StartTime > (ulong)inIntervalAlert * 1000)
  {
    static int Pos = 0;
    
    const int ServerPoint = Pos++ % inMaxPoints;
        
    Alert("CopyTicks error (timeout > " + (string)(CurrTime - StartTime) +
          " ms). Trying (" + (string)Pos + ") to switch to the " +
          (string)(ServerPoint + 1) + "/" + (string)inMaxPoints + " server point.");

    MTTESTER::SetServerPoint(ServerPoint);
  }

  return(rates_total);
}

int CheckCopyTicks( const string Symb = NULL )
{
  MqlTick Tick;
  MqlTick Ticks[];
  
  ResetLastError();
  
  if (SymbolInfoTick(Symb, Tick))
    CopyTicks(Symb, Ticks, COPY_TICKS_ALL, Tick.time_msc - 1000000, 1);
    
  return(_LastError);
}

The indicator makes all running Expert Advisors/scripts exit the corresponding timeout error at once. And then they continue to work normally.

Please give me real cases when you need to work with CopyTicks in an Expert Advisor all the time. I really use it only in OnInit() to get some historical ticks to run digital filters. In MQL4 I had to wait several minutes for buffers to fill up.

Do not skip (and do not double) ticks on Real, as it happens in Tester. The Expert Advisor on Real receives exactly the same sequence of price data that it will receive in Tester when you decide to run it on the past interval in the future.

I must be a complete idiot or missing something.

If I have an EA which I would like to run a single non-visual test (not-optimisation) of each day for a year...So Each day is tested with the hardcoded parameters how would I do It? Could someone please write a short tutorial like.

1. Download library - Install Instructions

2. Write this code to select your EA by name in your ea and such and such a file.

3. Select your start and end dates here

4. Specify Period and length of each back test here.

5. Add these additional codes to make everything function correctly get your #includes in the right place etc

6. Specify and save results to csv for each daily backtest.

Etc etc etc etc

I am lost on how to implement this soslution which seems like this library is specifically built for @fxsaber I have read all your short examples and went over the code in each file and cant seem to find any documentation that describes use cases or a step by step guide anywhere could you please help me figure this out?

Thanks for coding what we all wanted and needed your a legend love some of your comments like "!Did" when someone is asking you to fix something

Added functionality.

Sometimes you need to do the same thing on working terminals. Automation of this action below on the example.

As a result, one click collected data from all terminals. Thanks to MTTESTER::RunEX5 - runs EX5 on the required terminal (portable).

Application.

[fxsaber]

The script shows which of the running terminals are portable.

#include <fxsaber\MultiTester\MTTester.mqh> // https://www.mql5.com/ru/code/26132
  
void OnStart()
{
  HANDLE Handles[];
  
// Run through all the terminals
  for (int i = MTTESTER::GetTerminalHandles(Handles, false); (bool)i--;)
    Print("\"" + MTTESTER::GetTerminalPath(Handles[i]) +
          "\" - " +(MTTESTER::IsPortable(Handles[i]) ? "portable." : "NOT portable."));
}

Hi

I need running a script(located in \MQL5\Scripts\) by clicking on an object created by an indicator (located in \MQL5\Indicators\)(not by Hotkeys).

I have tried to use MTTESTER::RunEX5 but there are lots of basic errors. What am I doing wrong?

I have past "MultiTester_Example1" and "MultiTester_Example2" in \MetaQuotes\Terminal\D..5\MQL5\Experts\fxsaber\MultiTester.

I have past "MultiTester.mqh" and all other .mqh files in \MetaQuotes\Terminal\D..5\MQL5\Include\fxsaber\MultiTester

these are the errors I have received

Uncompiled code technically cannot be published in Codebase. The problem is on your side.

portable-restriction removed.
