Find support and resistance levels.

A good place to buy a stock or any security in the market is near the support levels. That support is usually a previous reaction low. The best place to sell a market is near resistance levels. Resistance is usually a previous peak. After a resistance peak has been broken, it will usually provide support on subsequent pullbacks. In other words, the old “high” becomes the new low. In the same way, when a support level has been broken, it will usually produce selling on subsequent rallies – the old “low” can become the new “high.”
