I have no intention of riling up anyone, but as a learning trader it is good that we discuss facts with one another. The first truth is that there is no spare money anywhere in the world; every money are valuable. To improve your trading psychology, you must practice your trade strategies on a live trade; even if you start out with 10$; you need to feel the heat, be under pressure.
Trading is for individuals who can afford to lose money, so if you cannot afford to loose money; please do not trade. In trading we are here to multiply money and not create it; live trading helps you compound losses or multiply money; while demo trading creates money for you.
No risk, no reward; start practicing your trading strategy on a live trade; even if it is 1$; feel the heat and develop instinctively.
