"The Trader Workstation (TWS) is our full-featured java-based trading and order entry application. The TWS demo mirrors the actual TWS in both form and function except market data is simulated based on the previous week's ticks and orders are not actually executed and cleared. However, TWS functionality will be identical to the actual application. "
