// @version=5
// author=theasgard and moonshot-indicator (ms)
// year 2021
//
// This is a well knowen strategy by using 3 different Supertrends and a trend-defining EMA,
// feel free to play around with the settings, a backtest on 8h ETHUSDT pair brought some good results using 
// the 233EMA and investing 75% of a 10k start capital
//
// the idea is to have at least 2 supertrnds going green above the trend-EMA to go long and exit by turning 
// 2 supertrends red (idea: 1 supertrend in red could initialize a take profit)
// shorts work vice versa
// The EMA shows in green for uptrends and in red for downtrends, if it is blue no Signal will be taken because 
// the 3 supertrends are not all above or below the trendline(EMA)
//
// Update 1:
// Fixed a minor input error
// Added ATR stoploss, and commented out the percentage stop loss
// Added time window to backtest
// Added exit on risk/revard is met
// This version is only buy...wait for next update adding shorts
