Wait for 30 seconds before plotting buy or sell signals in amibroker - amibroker

Question

Hi I am new to coding and i am trying to automate using the given code. I found an afl for intraday trading which sometime repaint signals. I want the system to wait for 30 seconds if its a 5min candle, 90 seconds for 15min candle so on.
I tried using
SecsSinceUpdateNum = DateTimeDiff(dateNowNum, lastSymbolDateNum);
timenum();
function to get the time of signal generated and compare whether the signal exists after 30sec if true plot buy or sell signals.
please help me with the code. thank you in advance
