In MQL5, you can create a function to check if the current tick is the first tick of the M1 (1-minute) timeframe by comparing the current time with the last time a new M1 candle was opened. Here's a sample implementation of such a function:
`c++
//+------------------------------------------------------------------+
//| Check if the current tick is the first tick of the M1 timeframe |
//+------------------------------------------------------------------+
bool IsFirstTickOfM1()
{
// Get the current time
datetime currentTime = TimeCurrent();
// Get the time of the last M1 candle
datetime lastM1Time = iTime(NULL, PERIOD_M1, 0);
// Check if the current time is equal to the last M1 candle time
// and if the current tick is within the first second of the M1 candle
if (currentTime == lastM1Time)
{
// Get the current tick's time
datetime tickTime = TimeCurrent();
// Check if the tick time is within the first second of the M1 candle
if (tickTime < lastM1Time + 1) // 1 second after the M1 candle opens
{
return true; // It's the first tick of the M1 timeframe
}
}
return false; // Not the first tick of the M1 timeframe
}
`
Explanation:
TimeCurrent(): This function retrieves the current server time.
iTime(NULL, PERIOD_M1, 0): This function gets the opening time of the last completed M1 candle.
Comparison: The function checks if the current time matches the last M1 candle's opening time and if the tick time is within the first second of that candle.
Usage:
You can call this function in your main trading logic or within an event handler to determine if the current tick is the first tick of the M1 timeframe.
