No, I don't think most people trade options intraday.
The bid/ask spread is usually very high compared to other instruments, trying to trade options intraday like another kind of liquid instrument is not a good idea. I don't know for weekly options, I never used them and didn't check about them.
For monthly options I think the trades last weeks or days, but not intraday.

Trading options intraday can be very profitable. The key is finding those stocks with highly liquid options where the underlying can move a few $ a day. I know some people that are killing it intraday as long as there is movement, whcih is key.
The good thing is that you can buy the calls or puts and not worry about having to short a ticker like $AAPL outright, just buy the puts. Find the trend on a lower timeframe like 30min then time the entry on a 3min or 5min that coincides with the 30min. Yes, these options are very expensive but start with only buying a few ATM. You will see that they move very well with the ticker; the premium moves well with the ticker. High options volume means very good liquidity and good fills.
Instead of watching the market to see how the options move simply pull up an intraday chart of an ATM option. Example: $NFLX had a very good range on Friday while the indices were kind of stagnant. Take a look at the intraday chart 113 Call on $NFLX per the moring move. No need to look at the monthyl opions, just the weekly that still has at least a few days left. If they are expiring 'today', look at the next week. You will see a very good % increase.
