You are mistaken! Sockets work in both MQL4 and MQL5:

• Socket library for MT4 and MT5

You have to enable DLL calls in both your main "Options" as well as when you attach the Indicator/EA to the chart ...

Please understand that the OnTick() event handler is called on every tick, just as the name states. That means that there can easily be 10s or more calls per second. If your alert condition is based on Time (seconds), you can easily have it being triggered multiple times within the same second, nor is there a guarantee that a tick will arrive at the zero second in order to trigger the alert.

Consider a flag to determine if the alert has been triggered or no,t or maybe a different type of trigger, or using the OnTimer() event handler instead.

However, I suspect that your understanding of MQL4 is still somewhat "green" and in that case I suggest some extra reading may help you out:
