One of the causes of the margin call is because the Learning Method / Trading System Is Not Complete. You should study the method one by one first, not all of them are used as if the water in the drum is inserted directly into the glass, certainly more is spilled. From the results of the analysis, a beginner trader always changes the system yup that's normal lain there are other people who succeed with the system and we learn it uh it turns out that when practiced loss and loss even to capital out, uh ... verdict that the system is bad even though it is new try 1, 2x only. Continue to change the system again, then there is a new practice again ... and in the end instead of loss & loss and that's what I did first
