I sometimes trade straddles on expiration day after implied volatility cools down dropping for a bit after the open and when the underlying crosses a strike price. Works well on some stocks, doesn't work well on others. If it doesn't start moving quickly after I'm in I'll close the trade for a small loss. I also trade credit spreads but am always worried about the risk/reward so I only really trade those when volatility's relatively high and I can go far out for premium.
I use options for directional bets on stocks. I dont trade options just cause it's cool, I trade for the leverage and risk benefit. Ofcourse their's a disadvantage, eventhings has a price, time decay.
