Unless you are an "insider", all information you receive is at least 2nd hand. "Someone" has had the information you just received for hours, days or weeks. They have an opportunity to make "moves" in anticipation of you (and thousands) other traders' actions.
If you want to make money in stocks, do it like Warren Buffett does it. Buy (high) quality stocks and hold for decades. Start at age 25 and retire wealthy.
I wouldn't trust other peoples' judgement on stocks, especially with options, due to the high risk and high potential for losses. They offer you zero reimbursement if they make a bad call, and no guarantee for whether their signals are accurate. Some may even be known to delete posts or tweets, to up their success rate.
I would advise against freeloading option calls posted by random people on the Internet. Ordinary stocks, okay, since the loss won't be major, but options is a major no-no. Even if they are reputable, as I said, they offer you nothing to cover if their calls are wrong.
You're better off playing options the right way, which is NOT trading them. They're meant for their original intended purpose: long-term investment in a company at a small premium.
If you buy in-the-money (or out, if you're willing to take a bet) contracts that expire 3+ months later, and the stock goes your way, you actually earn more than trying to trade short-term contracts. Trust me on this one. Delta rockets to 99% with theta dropping to less than 1% once your contracts are in-the-money, and if you have an extra month or two remaining, you earn extra for as long as it's ITM. Each month yields you an extra $1-2 in contract price.
If you don't know how to find signals yourself to trade options for, you probably shouldn't trade them at all. Following somebody's advice for options is like following a "professional" horse racing announcer's picks.
On twitter (or stocktwits), are there any good people to follow that give you actionable option calls? I have started to follow @thetradexchange and they seem to be good with real-time option plays. Anyone else have any success with them? or any other similar service? Twitter is mostly bogged down by traditional headline news and not options. Thanks!
