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.
// List of my work: 

// Multi-timeframe and price input

// MA calculation

I love this script and been using it for a little while but I was wondering how do I make an alert telling me when the buy and sell is?

I added these two lines

alertcondition(Buy, title="Buy BTC Alert")
alertcondition(Sell, title="Sell BTC Alert")

Maybe I'm a bit confused with how to set it up in TradingView's alert system?

@Ddraig, I would like to set up an alert when 4 time frames indicate a cross 2 with range candles 2 normal is this possible?

@Ddraig, The function creates alert condition that is available in Create Alert dialog. Please note, that alertcondition does NOT fire alerts from code automatically, it only gives you opportunity to create a custom condition for Create Alert dialog. Alerts must be still set manually. Also, an alert triggered based on a custom condition you created in Pine code is not displayed on a chart.
I'm very interested in using this for equities swing trading. Is there a way to program a scanner for stocks that meet the specifications?

I like it for displaying my 3/8 ema cross, to open/reverse following week. KISS!
@tim.turenne, how can i implement this script to alert me when crossing is ocurring on H4 or H1 timeframe?
