The first step is not capital management. You should first build a trading system. Next you should analyze the strong and the weak points of this system. And based on this analysis you should organize capital management. If you want to avoid big capital losses you should first know where the risks are. Risks are different for different tradingsystems. Working with a capital management system without knowing what you should watch at is difficult. There is no universal capital management system that is optimal for all kind of traders or tradingsystems.
