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.
It can be used for storing and reading variables as shown below.
Example usage for storing values:
IndicatorParams iparams;
iparams.max_buffers = 10; // Maximum last values to keep.
iparams.dtype = TYPE_INT;
Indicator *in = new Indicator(iparams);
MqlParam entry;
entry.integer_value = 1;
in.AddValue(entry);
entry.integer_value = 2;
in.AddValue(entry);
Print(in.ToString());
delete in;
Example of initializing the class without the parameters:
Indicator *in = new Indicator();
in.SetName("MyIndicator");
Print(in.GetName());
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.
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 to measure execution 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 to measure execution 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
}
The purpose ofTimer class is to measure time between starting and stopping points.
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;
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;
