One of the most common ways to imply SMA (Simple Moving Average) in trades are using multiple SMAs at the same time and trade the crossover. In my strategies, I would normally use 3 SMAs which is call the Rainbow Strategy. The following parameter is what I think is suitable for binary option trading.
How does it work?
When using multiple SMAs, traders would use the long term SMA (SMA3: Yellow) to identify a trend direction. And to trade at the crossover of the 2 short term SMAs (SMA1: 7 & SMA2: 13) when they gives out a signal that matches with the trend direction. Very simple strategy, and perfect for beginner to get a hand on trend direction and trend reversal. Take a look at the following video to find out more about the strategy!
