asking about EA refresh time

Hello
I am developing an expert prototype.
i have an idea but i need help.
I need to know if we can incorporate a command line so that the expert checks the data every second and no longer relies on the tik candles on the different timeframes.
that is possible ?

I am a professional trader but I am new to MQL programming
thank you
