I really have had no bad trades, atleast in recent modern years.
My worst trades all hovered around when I was an amateur in 2008/09 -- when I jumped into the market headfirst.
I made every rookie mistake in the book.
I held onto a couple losing trades...hoping and praying and convinced they would go back up.
And, more or less, as just my luck would have it...they rebounded, kind of, just as I have sold them.
Back then, I was just a jackoff gambling...into the Quarterly Earnings game with stock

,

I would essentially go all-in and pick a side. Ride the wave, and immediately cut losses. Simple enough, right?
I have definitely wised-up my game since then. and maturity. and market wisdom. -- and overall tactics.
Ten years since that point, now in 2018...I am Making Trading Great Again...High-Five`
I am so glad I can teach my expertise wisdom to every ET, extraterrestrial trader, here.
I need a medium-rare porterhouse steak, and salad, and double espresso. and whiskey.
