Forex trading on your own is not difficult. Obviously the toughest part is in the very beginning. Your wet behind the ears, nervousness sets in, and doing something as complicated and complex as the foreign exchange by yourself can be overwhelming as well.
At the most basic level, people who are ready to do forex trading on their own have studied the trading charts, educated themselves on forex trading, developed a winning and profitable trading strategy, have put into practice that strategy into a free demo account where they earned a profit and you are now ready to do forex trading on your own with real money.
Getting started forex trading on your own is important to get going on the right track. Its easy to discouraged right away if you begin losing real money and to leave your position before losing any more money. You may have a winning strategy to win for the long term however your trading strategy is currently not working when you begin trading.
Many people who begin losing money right away will end up making a trade or set of trades they would not normally make in order to try to recoup their losses. You never want to guess at making a trade. You should always have a reason for making a particular trade within the forex market and an exit strategy for leaving the trade even if it begins to lose.
Personally I think the hardest thing when starting out on your own is learning how to exit the trade. If you end up trading for a while you will make trades that lose, trades that win, and end up leaving trades for a profit that end up winning even bigger profits.
Also do not get overconfident in the beginning if you begin making winning trades. You might get too excited and begin going above your budget because of the ability to make some quick cash.
Doing anything in groups or as a team will make any job or project easier. With forex trading many people are on their own. It requires a lot of work and research to make trades. Its easy to make a trade with bad advice in a forum or article, gut feelings, or just trying to get lucky in order to make trades due to laziness. The most successful forex traders will tell you they work hard in order to make their trades. This is what fx trading on your own entails... hard work, research, and continous learning.
