Is there a "fastest" way to get filled on a potential short sale with TWS (or any platform for that matter)? I route my short orders thru SMART as a limit order and it always takes forever to get filled. I know about the uptick rule but I'm always seeing bids come up thru my offer AND trade higher, but still no fill. This usually happens on my small lot trades - 75 shares. Could the size of sub-100 lot be the reason? Thanks, anyone?
