## Crosses with indicators

Crosses with indicators are composed of two indicators crossing each other. These could be used to detect breakouts. For example when a shorter period indicator crosses above/below a longer period indicator to detect a bullish/bearish setup. This concept can be applied to many types of indicators such as moving averages, prices (i.e. OHLC) and oscillators.
