Having trading strategy is necessary, but it is also necessary to implement it correctly. Don't get in trap of BS sellers, no fear and no greed, etc. - this all is full of sense , but in order to make sure that strategy works fine, demo account would be the most appropriate first step. If demo performs good trading for at least several months, one may change it to micro account, if success is repeated, then it is the time to open real account. The first and the most important rule for absolute newbies is to forget once and for all the idea about easy cash.
