Understanding the market is the key, and this is not something that you can achieve quickly. It takes time and experience can then be built over time. Risks will always remain, regardless of how experienced you are. The only difference is that you will be able to better understand what you are going to do, and with your previous knowledge and experience in trading you can minimise those risks. There are tools which are helpful too. At the end of the day timing matters agreat deal too.
