Read the Reminiscences of a Stock Operator before talking to me. My twits are my and my dog opinions, not advice. I am often wrong and I love it. PS: I DO NOT short single stocks and I do not answer 3x ETFs questions.
These past few years have taught me patience. Manage position size. Tighter stops. Pick entries carefully. I make mistakes and am still sometimes undisciplined. Laugh and more importantly, learn.
I've done my due diligence. Now you do yours.
