I once asked a broker if they could provide me with a weekly list of positions on their clients accounts with all identifying information removed so I could fade them. He said no….
You just have to turn pro and be a market maker, you will see all of the positions. I actually bet against myself by buying options. I started out like every retail, did CC and CSP. Not making any real money after ~ a thousand trades, so I reversed and bought.
I am only legging into a position that cannot be open by a exchange-traded spread order Legging in can be costly especially in the long run. It's not worth it for me. I hold positions for weeks and months usually so I am ready to give up couple ticks I lose by not getting a legging "discount"
You must not be a real trader. For us traders, volatility is our friend. A market without volatility is not tradable.
