Keep your loss at an acceptable level is the risk management. That is the first lesson that everyone need to learn first before entering the trading financial market, but it's also the part that be ignored the most because when they begin to trade, they just only focus on profit first, not be the risk which they will might lose.
True, very many people who start trading in the market only focus on profits and ignore the risks they have to accept, indeed that can also be said to be fair, because with them focusing on profits, then indirectly it will always be a motivation when they start working, although the risks must also be understood when they start working in any trade.
