Your Quant Savvy systems are loaded into Multicharts/Tradestation automated software. The systems generate trading orders automatically which are then transmitted in real-time to your broker. The broker then executes the orders. Each system will automatically manage all aspects of the trade for you, from entry to exit.
The systems are dynamic and not static, meaning they react to live data coming into the market. Before any trade is placed, the systems calculate the risk and expected payoff and will always have dynamic stops and targets in place.
