My suggestions:Last year continued to buy long calls on AAPL while it was tanking and thought..oh it will go back up sometime. IV crush killed my calls. Also had a terrible trade on VRX selling bull put spreads and also buying the stock because it was cheap IMO
1. Don't short any naked options, especially OTM options. Your mistakes can blow up your account faster than you can react, even with stops (gap up/down happens more often than you think). Remember: limited gain, (almost) unlimited loss.
2. If you are doing directional bets like what you did with AAPL, try to do longer duration options as short expiry options depends on too many factors: IV, directional, time decay and you maybe correct with directional but your short duration options just do not have time to develop.
How do I know? As a small mom and pop retail investor, been there done that.
Good luck.
