I have losses every single day, it is frustrating, but it is one of thousands in lifetime and by next day I forgotten it. As to my Trading Plan, I didn't do anything wrong, so the Plan lost. Maybe not buying much in October is the answer,

. I normally only trade Dow30 (love the dividends and must have decent volume options and several ETFs). I would have done same exact trade again just as I did.
I was buying trendline bounces-trend up, Protective stop is August lows good support, first trade bought on limit and did Put Credit Spreads, each day after I sell Calls when price hits BB, next couple days selling Calls, 2nd stock entry another trendline bounce, oh boy it open lower so better price and I will do better on doing the Put Credit Spreads, positive by close and sell more call options and heavier volume-profs accumulating, next day opens on BB, sell more calls, but......bath day, lose on stock, lose on Put Spreads but made on Calls. Over all loses, calls saved me a bit.
Happy Holidays All
