A trading system is a set of parameters that predicts the price movement of a currency. Most experienced traders will use a trading system because it helps to determine when to enter a trade, how long to hold it, and when to sell and take a profit or accept a loss. These are decisions that traders make every day in every trade. Using a good trading system will not protect against a losing trade. However, it will help to keep losses to a minimum. It can also maximize the profits on each trade. In short, a trading system takes much of the guesswork out of trading.
