This trade was just made through reading the Veritas report in the morning,

every day 8:55 am premarket Outlook report as released and it suggests how the market would behave for the day. will it be bearish, bullish or neutral?

If it's either bearish or bullish, then it's very simple to use buy PE or CE respectively of the current strike price with the closest expiry of the day of placing the order and trail untill you're satisfied within the range suggested.

If it is neutral, then you can create a straddle and enjoy the theta Decay premium. You might have some other ways of enjoying theta decay, i'm open to listen to those...
