Buy BX by Sep 4, 2026.

I have a large stock protective put position on 10,000 shares of Blackstone. My broker wont let me close the position in a single trade(shitty broker). I only have 100,000 in available margin in this account so i cant close out the options or shares in a single trade. The puts are weekly 122s, pretty deep itm. I want to exit to buy leaps. Any advice on an exit? I don’t want to do 20 transactions of selling some puts …
