Moving Average Cross Alert, Multi-Timeframe (MTF) (by ChartArt)

See when two moving averages cross. With the option to choose between four moving average calculations:


The moving averages can be plotted from different time-frames, like e.g. the weekly or 4 hour time-frame using HL2 , HLC3 or OHLC4 as price source for the calculation. In addition there is a background color alert and arrows when the moving averages cross each other when the price also rises or falls. And the moving averages are colored depending on their trend direction (if they are trending up or down).

// ChartArt's Moving Average Cross Indicator
//
// Version 1.0
// Idea by ChartArt on September 15, 2015.
//
// This indicator shows when two moving averages cross.
// With the option to choose between four moving
// average calculations:
// (SMA = simple moving average)
// (EMA = exponential moving average)
// (WMA = weighted moving average)
// (Linear = Linear regression)
//
// The moving averages can be plotted from different
// timeframes, like the weekly or 4 hour timeframe.
// With the possibility to use HL2, HLC3 or OHLC4 prices.
// 
// In addition there is a background color alert
// and arrows when the moving averages cross each other.
// And the moving averages are colored depending if
// they are trending up or down.
