Humans have little chance against a well programmed forex trading system. All the key decisions including currency pairs, entry points, exit intervals, loan to equity for each trade, and the limit orders can be instantly executed with a programmed forex trading system. Though currency or fx trading systems are complex beasts, even setting up the basics of currency pairs like CHF/GBP, how high to borrow from 1 to 75, etc., or when to enter and exit the trade can be enough to make the software pay for itself. By quickly producing orders that would require precious minutes if done manually, a forex trading system can lock in profits and prevent or cut loses in an instant. Only the programming of the forex trading system software must be tuned to assure it is a productive rather than a destructive tool
