Any activity works on instincts coupled with solid money management and risk management techniques. The system is required to put an end to an activity say it is for profit or loss. You cannot be waiting too long to take a decision be it on the positive or negative side of the aspect. Basically system are made to ensure the smooth flow of the strategies and they are absolutely required to put an end to some activity. When you attach a money management system with a solid assumption of the resultant profit or loss, you can be protected from the danger of extreme volatality.
I have tested many automatic systems in currency trade and found that it is basically formed to make as many trades as possible with a 1:2 or 1:3 risk to reward proportion that upon every one loss, two gain should compensate a loss and put you in profit. Or may be for every 1 penny loss, 3 penny profit can offset the loss and result in ultimate profit. Sometimes what happens is that there may be seres of losses for example 8 or 9 yet, the automatic systems will continue to trade on the set patterns. Under such circumstance, one or two profit trades cannot make good the loss and the market may not help the system to arrest the flow of losses and the equity can easily get blown off.
It is only the manual trade or human intervention with some visual appearance of the price action that can take control of the situation. The lastest of my observation reveals that all indicators and expert advisors do not work continuously over a long period of time and at some point of time, it requires human intervention to repair the damage. There is no holy method to claim that “this is the most successful system” and anyone who comes out with such a claim is a crazy statement.
Should you need to observe my visual instincts for a period and see what I am exactly trying to say, you need to visit Daily Recommendation page of my website. You are free to write your comments, get answers or even try with one of your demo accounts or real accounts to test the waters. I am not claiming to the readers you can make a huge ransom with currency trade, but it is a sustained effort that profits can grow tick by tick. One of my recommendation is given here, as an image for your study and observation.
