When it comes to price patterns, the most important concepts include ones such as support and resistance. Put simply, these terms represent the tendency of a market to bounce back from previous lows and highs. Support is the market's tendency to rise from a previously established low. Resistance is the market's tendency to fall from a previously established high. This occurs because market participants tend to judge subsequent prices against recent highs and lows.
Apart from the entry/exit rules and optional money management guidelines, strategies are often characterized by the list of trading tools required to employ the given strategy. These tools are usually charts, technical or fundamental indicators, some market data or anything else that can be used in trading. When choosing a strategy, you need to understand, which of the required tools you have in possession.
