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.

hi, such a great idea and script :)

im trying to make it as a strategy for back testing


I wrote :
if (buy)
strategy.entry("buy", strategy.long)


if (sell)
strategy.entry("sell", strategy.short)

but im getting error as ( line 43: syntax error at input 'end of line without line continuation' ) with @version3 and ( line 43: no viable alternative at input 'end of line without line continuation' ) with @subversion23

any help please :(

@btcmstr888, I mean line 43: no viable alternative at input 'end of line without line continuation' with @version2

@MDicko123, I figured it out. short trend line crossing down long trend line = SHORT/SELL. Short trend line crossing up long trend line = LONG/BUY.

Does this repaint?

FYI - this NOT really a multiple time frame indicator is it?. It is a single time frame but user programmable.
AN MTF usually means it calculates and displays multiple timeframes SIMULTANEOUSLY - the idea being you can visually compare crossover readings AT THE SAME TIME. Just saying ...

Is it possible to have set this up as a 9 EMA and 20 SMA?

Nice.

One question - on my candle chart this turns some red candles orange, some green candles are changed too....?
