Successful Forex Trading System

Forex trading system is the subsystem of the forex trading plan which governs when and at which price you open and close your trades. A trading system works on the signals given by technical analysis and/or fundamental analysis. The signals are taken to see if the trader should buy or sell a specific currency pair or must close the open position(s). Any currency trading system prevents information overload by filtering out the universe of technical and/or fundamental signals in such a way that only the most reliable (successful in the past) signals or signal combinations are acted upon.
There are two kinds of trading systems - the discretionary and the mechanical. Discretionary trading systems expect the trader to use his or her own judgement to ascertain the importance of each of the technical or fundamental signals (whose number is potentially infinite) that he or she gets. Mechanical trading systems operate on a fixed number of technical or fundamental signals without the participation of the trader. Discretionary trading systems require the perpetual application of creativity (flexibility of approach) from the trader in the understanding of the changing market conditions. Mechanical trading systems require the creativity from the trader only in the forex system development phase.
Discretionary forex trading systems are best employed by professional forex traders with a lot of experience (internalized practical market knowledge) against which they can determine the validity of any signal that they receive. These traders usually remember a large number of various signal patterns from the past (just like the master chessmen) that they can compare to the current market conditions, to make their analysis more objective. In essence, they use themselves (i.e. their brain) as their trading system - often very successfully - because human mind has the best pattern recognition power on the planet.
Starting currency traders are advised to begin by following professionally created mechanical forex trading systems. Most of these systems are sold-out in the form of the forex signals that are usually developed by experienced traders who have found a way to systemize their knowledge of the markets into a working strategy. At the same time, the beginning traders can work on building their own knowledge base of the forex market through the quality forex books, educational courses, bank reports and newswires on this subject -so that they can too, with time, create mechanical trading systems from their own insights and intuitions (using the forex charting packages which allow to do this).
The aim of an exit system is to protect the capital base and the unrealized profits. The capital base is shielded by ensuring that the trades are exited with a fixed loss when the reasons for holding them are no longer valid. This is done by triggering a stop-loss order on your forex brokerage account when the price crosses the level which defined your risk at the entry. If you are a discretionary trader, forcing yourself to place the slop-loss on each trade and to stick to it no matter what will make you very selective about your entries - which ought increase your profitability. The unrealized profits are protected either by a take-profit order which is triggered on your brokerage account when the price reaches the level which defined your profit at the entry or with the help of the trailing stop-loss which gradually locks in more profits as the price moves in your favour. In fact, the trailing stop-loss exit can be more suitable than the fixed take-profit exit if you wish to profit from the extending "character" of some impulse waves. In such a event the trailing stop-loss can be placed just a few pips opposite to the trendline which defines impulse wave. There is one more type of exit which can be used to protect the trader from missing trading opportunities - the time exit. A time exit is triggered if a trade hasn't reached either its stop-loss or take-profit level in the specified period of time. Exiting such trades reduces the chances that the capital will be tied up when better opportunities appear on the other currency pairs.
