I did a simple analysis for all my option trading for this year. My average profit for each contract is around $10. I am a spread trader. Since $10 a contract = 0.1 for each share and 0.1 is usually the bid ask spread. If I paid an extra 0.1 for each share I traded, I would have lost money. Can any successful option traders share their performance here? I want to know when is a good time to size up.
