the biggest challenge is to take this business seriously the decision to become a forex trader is a life-changing one because you could go to one of those paths through the way which are
1-you might lose a significant amount of money
2- you may get stuck for many years in it without being profitable ( even breakeven is a time-waster)
3- you might lose your social life while you are in point number 2
how can you take this business seriously?
this is a lot of hard work
1- you must read and learn everything about forex trading from brokers to platforms to asset pairs to fundamental news and how it affects the forex market etc etc ...
2- you must demo trade or use a cent account with 100-500 USD budget and keep doing so until you have a clear system that is not making you overtrade, overstress, gamble. that have clear and identified goals in terms when you enter and exit a trade when you should stop trading.
your main goal as a beginner is not to make a profit and not to have a good setup your main goal should be creating a profitable consistent stress-free trading system. that have clear goals and clear ext plans.
3- you must never let your emotions control your trading, the moment you make a trading decision based on an emotional feeling this could be based revenge trading, gambling trading, it can be called anything except a business
that's why i said first the biggest challenge is to take this business seriously
