The working principles

In many jobs common people are paid for their working hours, being rewarded with the amount of working-time spend for the period. In FOREX trading a private person can get the reward for being right, while the working period may be not so hard as in the office.
Personal activity and the ability to learn are not of the last kind for success in this. Some people can learn trading in several weeks or months, other spend 30 minutes a day and the they are good traders with huge profits.
Common FOREX strategies for trading can be best for working in a demo-mode. If you build too simple personal strategy, this can be not good, but too complicated one will also break and lose. The main point is to keep this strategy simple enough and wise enough while seeking profit.
The good trader need to obtain strong self-discipline, and this is the main part of FOREX participating, because you need to trade even if you have losing periods and stay on the spot for the winning-time period. If you don't have strong self-motivation to follow the main rules of the market, you will have nothing as a result.
When you trade you should follow trading signals from the needed level and have to stop just in time to follow volatility. It is not an easy task, much harder to perform. Lot of traders first follow the direction the right way, but random volatility stops them, so trend is rather important.
