What is the best strategy to prepare oneself before entering the trading market?
You don't need strategy, all you need is enough funds to sustain on trading in order to manage your asset sustainably. Skills should be developed in order for us to cope up with different challenges, but that's normal for first timers to panic and worst is they lost a huge amount of money. Seek guidance from friends and peers who could mentor you for a good advice which eventually taught your different ways to deal with trading successfully.
