Classes

`Account` class

The class for managing the current trading account.

Example 1 - Managing account (dynamic calls)

Account *acc = new Account();
double _balance = acc.GetBalance();
double _credit = acc.GetCredit();
double _equity = acc.GetEquity();
double _margin_free = acc.GetMarginFree();
double _margin_used = acc.GetMarginUsed();
if (acc.IsExpertEnabled() && acc.IsTradeAllowed()) {
  // Some trade code.
}
delete acc;

Example 2 - Managing account (static calls)

double _balance = Account::AccountBalance();
double _credit = Account::AccountCredit();
double _equity = Account::AccountEquity();
double _margin_free = Account::AccountFreeMargin();
double _margin_used = Account::AccountMargin();
if (Account::IsExpertEnabled() && Account::IsTradeAllowed()) {
  // Some trade code.
}

`Dict` class

Use this class to store the values in form of a collective attribute–value pairs, in similar way as associative arrays with a hash table work.

Example 1 - Storing string-int data structures

Example of storing key-value data with string as a key:

Dict<string, int> data1;
data1.Set("a", 1);
data1.Set("b", 2);
data1.Set("c", 3);
data1.Unset("c");
Print(data1.GetByKey("a"));

`Mail` class

The purpose of Mail class is to provide common functionality for managing e-mails.

Example 1 - Send e-mail on trade execution

Example sending e-mail on trade execution:

int OnInit() { // @see: https://www.mql5.com/en/docs/event_handlers/oninit
  Mail *mail = new Mail();
  mail.SetSubjectPrefix("Trading");
}
void OnTrade() { // @see: https://www.mql5.com/en/docs/event_handlers/ontrade
  if (!Terminal::IsRealtime()) {
    mail.SendMailExecuteOrder();
  }
}
int OnDeinit() { // @see: https://www.mql5.com/en/docs/event_handlers/ondeinit
  delete mail;
}

`Indicator` class

The purpose of Indicator class is to provide common functionality across all indicators such as storing and searching for values.

This class is used as a base class to handle technical indicator classes which can be found in Indicators/ folder.

`Indicators/` classes

In Indicators/ folder there is collection of indicator classes.

Example 1 - `AC` indicator

The example reading value from AC indicator:

#include <EA31337-classes/Indicators/Indi_AC.mqh>
int OnInit() {
  Indi_AC ac = new Indi_AC();
  PrintFormat("%g", ac.GetValue());
  delete ac;
}

Example 2 - `Alligator` indicator

The example reading values from Alligator indicator:

#include <EA31337-classes/Indicators/Indi_Alligator.mqh>
int OnInit() {
  AlligatorParams alli_params(13, 8, 8, 5, 5, 3, MODE_SMMA, PRICE_MEDIAN);
  Indi_Alligator alli = new Indi_Alligator(alli_params));
  AlligatorEntry values = alli.GetEntry(0);
  if (alli.GetFlag(INDI_ENTRY_FLAG_IS_VALID)) {
    Print("Alligator values: ", values.ToString());
  }
  delete alli;
}

`IndicatorData` class

The purpose of IndicatorData class is to store indicator data. It is basically alternative implementation of Indicator class.

For more details, please read: Class to hold indicator values.

For implementation example, check tests/IndicatorDataTest.mq4.

`Profiler` class

The purpose of Profiler class is to profile functions by measuring its time of execution. The minimum threshold can be set, so only slow execution can be reported.

Example 1 - Measure execution time of function multiple times

Example to measure execution time of function multiple times, then printing the summary of all calls which took 5ms or more.

#include "Profiler.mqh"

void MyFunction() {
  PROFILER_START
  Sleep(rand()%10);
  PROFILER_STOP
}

int OnInit() {
  for (uint i = 0; i < 10; i++) {
    MyFunction();
  }
  // Set minimum threshold of 5ms.
  PROFILER_SET_MIN(5)
  // Print summary of slow executions above 5ms.
  PROFILER_PRINT
  return (INIT_SUCCEEDED);
}

void OnDeinit(const int reason) {
  PROFILER_DEINIT
}

Example 2 - Measure execution time of function multiple times

Example to measure execution time of function multiple times, then automatically printing all calls which took 5ms or more.

#include "Profiler.mqh"

void MyFunction() {
  PROFILER_START
  Sleep(rand()%10);
  // Automatically prints slow executions.
  PROFILER_STOP_PRINT
}

int OnInit() {
  // Set minimum threshold of 5ms.
  PROFILER_SET_MIN(5);
  for (uint i = 0; i < 10; i++) {
    MyFunction();
  }
  return (INIT_SUCCEEDED);
}

void OnDeinit(const int reason) {
  PROFILER_DEINIT
}

`SymbolInfo` class

The class to manage the symbol's information.

Example 1 - Accessing symbol's data (dynamic)

SymbolInfo *si = new SymbolInfo();
string symbol = si.GetSymbol();
MqlTick tick = si.GetTick()
double ask = si.GetLastAsk();
double bid = si.GetLastBid();
uint spread = si.GetSpread();
Print("MARKET: ", si.ToString());
delete si;

Example 2 - Accessing symbol's data (static)

string symbol = SymbolInfo::GetCurrentSymbol();
MqlTick tick = SymbolInfo::GetTick(symbol)
double ask = SymbolInfo::GetAsk(symbol);
double bid = SymbolInfo::GetBid(symbol);
uint spread = SymbolInfo::GetSpread(symbol);

`Timer` class

The purpose ofTimer class is to measure time between starting and stopping points.

Example 1 - Single timer

Single timer:

#include "Timer.mqh"

Timer *timer = new Timer("mytimer");
timer.Start();
// Some code to measure here.
timer.Stop();
Print("Time (ms): ", timer.GetSum());
timer.PrintSummary();
delete timer;

Example 2 - Multiple timers

Multiple measurements:

#include "Timer.mqh"

Timer *timer = new Timer(__FUNCTION__);
  for (uint i = 0; i < 5; i++) {
    timer.Start();
    Sleep(10); // Some code to measure here.
    PrintFormat("Current time elapsed before stop (%d/5): %d", i + 1, timer.GetTime());
    timer.Stop();
    PrintFormat("Current time elapsed after stop (%d/5): %d", i + 1, timer.GetTime(i));
  }
timer.PrintSummary();
delete timer;
