The three moving average crossover strategy (3 EMA) is an approach to trading that uses 3 exponential moving averages of various lengths.All moving averages are lagging indicators however when used correctly, can help frame the market for a trader. You can see how MA’s can give you information about market states by looking at the Alligator trading strategy that I posted a while ago.Using moving averages, instead of buying and selling at any location on the chart, can have traders zoning in on a particular chart location.From there, traders can use various simple price action patterns to decide on a trading opportunity.
