A friend of me can locate shares to short on cobratrader: https://www.cobratrading.com/locate-shares-of-hard-to-borrow-securities/
There is a fee for the locating but still there is an offer, you like or not. Is it not possible to locate shares by paying locating fee in TWS like in cobra trading?
I think that IB doesn’t offer an additional share location service, only an automatic one where you simply place an order then it will get filled after/when short shares become available. This is great for everyone since everyone is treated equally and everyone may get some shares to trade/short. And it’s cheaper than other locate services. Even if you offered to pay more, everyone would do the same while the number of available shares wouldn’t increase, so you would still have the same problem but pay more for having the same problem. IB helps everyone save money equally, vs charging everyone extra fees, or allowing you to have advantage over others. So get in line with everyone else.
