Working AFLs for intraday trading system(only equities)

I want to learn Amibroker. I have searched online for intraday AFLs but can't find them.
I want some sample working AFLs that model intraday trading system (portfolio system for equities, not futures, options , etc).
Working doesn't mean profitable here. It means it doesn't throw out any errors etc while being run.
Can someone share them?

Thanks!
