Its very common to hear lots of people saying forex is risky, forex takes a long time to master, forex is a rigged market. But they never go into detail. It also makes me uncomfortable when the same people say that forex trading involves buying and selling currency. Oh really.....
Practicing on a demo account will give a trader confidence to tackle real currencies markets. The experience he will gain on the demo account is essential for them to be successful in the long run.
Money management and maintaining balanced trading psychology are the two challenges that most traders face. New traders become very eager and search for quick results, but it is not actually possible to become successful overnight by trading currencies. As a newbie, another big challenge is to be consistent with learning. If you can do that, then forex trading can be rewarding in the longer run.
The long run is all that counts. I generally post to new traders who want to be professional traders is, if they start with only £1000, it will take 7-8 years. This assumes they have an alternative form of income in the meantime and a consistently profitable strategy from Day 1. They generally don't reply and are never seen again.
The biggest challenge is to stay consistent and patient. As a newbie, you focus more on winning, rather on skills and development. It could be difficult to commit, but slow and steady wins the race. Therefore, if you plan to enter the forex market, commit yourself. Take small risks. learn first, and the rest will follow.
