Step 2: Selecting Indicators for Support Resistance Using Averages AFL
In most simple terms, support is defined at the price level from which market bounces up while resistance is the price level from which market goes down.
When prices bounce from the 20-period MA, we take that point as support level. When prices fall after touching 20-period MA, we that that price as resistance level. This is because most people use Moving Average Crossover for analysis/trading.
When the market is trending, we buy on the break of resistance. But when the market is sideways, we do not enter a trade at all. Plus Directional Index (PDI) and Minus Directional Index (MDI) indicators are used to determine whether or not the market is trending.
