Unfortunately, risk management is not being taught enough and many people find themselves losing money at their early days. (1st year)
In my opinion, everyone should be first investing in time in his own education, knowing exactly what are his plans, how much can he afford to lose to learn a lesson.
I've personally found it much more useful in starting with a logic trading pattern that made sense to me, and within time improving it and making my own algorithm. Now it is all about knowing your required margin based on your goal, and making sure that you have enough "fuel" to drive you "vehicle".
