History of Lek Securities:

Lek Securities Corporation is a Delaware corporation founded in 1990.  LSC is registered with the United States Securities and Exchange Commission as a Broker Dealer and with the Commodity Futures Trading Commission as a Futures Commission Merchant.

Lek Securities is exclusively engaged in the business of executing and clearing orders in equity securities, options and futures, as agent, for professional and institutional clients.  Lek Securities is known for the ROX
System, a PC-based order entry and management system that allows clients to electronically access the stock exchanges, electronic communications networks and market makers.

LSC started as a proprietary trading firm in 1990, making option markets on the American Stock Exchange. ROX was developed in response to LSC's execution needs on the floor. It provided LSC with fast, electronic access to the NYSE Super Dot System. ROX has since evolved into a sophisticated order management system with connections to stock, options and commodity exchanges worldwide.  LSC is no longer engaged in proprietary trading or market making of any kind.

Lek Securities UK Limited recently opened in London to better market and offer to the UK and Europe the same products and services that Lek Securities Corporation offers in the USA.  Lek Securities UK Limited is authorised and regulated by the Financial Conduct Authority.
