strategy("EMA Slope + EMA Cross Strategy (by ChartArt)", shorttitle="CA_-_EMA_slope_cross", overlay=true)

// ChartArt's EMA Slope + EMA Cross Strategy
//
// Version 1.0
// Idea by ChartArt on March 10, 2018.
//
// This strategy uses divergences between
// three moving averages and their slope
// directions as well as crosses between
// the price and the moving averages
// to switch between long/short positions.
//
// The strategy is non-stop in the market
// and always either long or short.
// 
// In addition the moving averages are colored
// depending if they are trending up or down.
//
// List of my work: 
// https://www.tradingview.com/u/ChartArt/

// Input
price = input(close)
MA1_Length = input(2,step=1, title="EMA 1 Length")
MA2_Length = input(4,step=1, title="EMA 2 Length")
MA3_Length = input(20,step=1, title="EMA 3 Length")

switch1=input(true, title="Show Bar Color?")
switch2=input(true, title="Show Moving Averages?")

// Calculation
MA1 = ema(price, MA1_Length)
MA2 = ema(price, MA2_Length)
MA3 = ema(price, MA3_Length)

// Strategy
long = crossunder(price, MA3) or ( change(price)<0 and change(MA1)<0 and crossunder(price,MA1) and change(MA2)>0 )
short = crossover(price, MA3) or ( change(price)>0 and change(MA1)>0 and crossover(price,MA1)  and change(MA2)<0 ) 

if long
    strategy.entry("Long", strategy.long, comment="Long")

if short
    strategy.entry("Short", strategy.short, comment="Short")
