We offer Prime Brokerage. Email me what you are looking for, so I have a better understanding. The most common reason why our clients do that is to get access to secondaries and IPOs at other brokers but exit those trades with us.
its to tap into dark/grey liquidity pools away from the exchanges (DASH ATS by way of example) in my case. What are the trade away fees at Lime?
We are no longer Lime. The list of dark pools available on Lightspeed Trader can be found here - https://www.lightspeed.com/pricing/routing-fees/. Sterling offers other Dark pools and Realtick has access to Dark pools through Algos. I can send you a list in a direct email if you want it.
