It would be sad to see the option selling discussion move away from TMC. I personally like to read about people's trades and experiences. It's a important learning tool. Getting feedback is also very helpful. And I cannot imagine that there are negative impacts by disclosing positions and trades. We're just small fish in a big pond and I cannot see market makers taking the time to find out what price someone is trying to get for 50 spreads. If that fears does exist you could limit yourself to telegraphing trades after the fact.
More than market makers, I expect the concern regards friends/coworkers looking at you differently if you reveal a massive portfolio. Oh sure, he/she doesn’t have to work hard on the job because they have this giant stock market cushion, or he/she won’t need a raise this year because they’re independently wealthy, or whatever.
That said, I need another slack channel like I need a hole in the head, so I’ll be staying here.
I don’t actually think revealing trade size has a big benefit… if the point is that it’s peanuts for you, or that it only represents a portion of your available cash/margin, you can just say so. Seeing trades with giant multiplier labels makes them seem less relevant to me since they’re so far out of my league… currently, anyway.
