The terminal is the main trading screen: a symbol list on the left, the selected company in the centre with its chart, financials and news, and order entry on the right. Market, limit, stop and trailing-stop orders all execute against a central limit order book with price-time priority, which means the depth displayed is the depth you actually trade against — a large order pays slippage by consuming real price levels rather than by having a penalty applied to it.

Prices are simulated, not fetched. Each company is valued as a fair value derived from its earnings and the prevailing interest rate, multiplied by a mispricing term that mean-reverts under herding, order flow and GARCH volatility. No real market data is used and no real money is involved.
