Better Execution

Siege MidPool fits alongside your existing execution workflows to reduce the market impact of your orders, reducing hidden transaction costs.

You can participate directly, if you face our central counterparty hub, or via an increasing number of execution algos provided by partner banks.

Orders placed in MidPool automatically ‘float’ as trades are bound in real time at a streaming mid-rate. Siege neither publishes nor sells market data, allowing your order to rest in the dark without signalling risk.

The larger your order size, or the less liquid the market, the greater the benefit of matching in the MidPool.

The Siege MidPool binds transactions at a regulated streaming mid-rate provided by New Change FX (NCFX). This rate is formed away from Siege and is unaffected by the act of submitting an order or trading in the MidPool.

NCFX is a FCA-regulated data and analytics company on the UK register of approved benchmark administrators. Participants and prospects interested in the NCFX offering should contact NCFX directly or see https://newchangefx.com/products/#data
