I am not a professional broker, but I have some experience in the capital market. Here are some 3 tips that, I believe, will assist new traders:
1) When the dollar goes down, usually strong commodities with monetary properties, such as gold or oil, go up.
2) When a currency loses its value, traders opt for alternative channels of investments to realize profits. For example, if the Euro goes down, the investors are likely to opt for European indices (e.g. DAX).
3) An upward trend of an asset can change 180 degrees in an instant. Financial markets are very volatile and tend to fluctuate. Always be alert. Hope for the best but expect the worst.
