Condition to only trade once per hour

[Bat Man]

Hello, does someone know a condition to trade only once per hour in mql5, i'm a begginer and having trouble to find something that i can undestand.

Or some ressource to learn more about it

Thank you

When in doubt, think!

static datetime lastTrade=0; datetime now=TimeCurrent();
if(now - lastTrade >= 3600){ // Only once per hour.
   lastTrade=now;
   OrderSend(…);
}
