Risk Tolerance :
Define your trading goals it,s may be short-term or may be long-term gain. If you prefer actively managing trading by market news then the shot trade is the best option for you. Profit and loss depend on the risk high risk may give you a high gain or high loss but a good strategy cover it deeply.
Among the list, this for me is more important. Because most of the new in trading are struggling with risk, some started with low capital but complain about profits or start with big capital.
Having risk management will solve it because it will help you to become a good trader and a good decision-maker. It will also help to protect your capital which is the most important when you are trading.
