//              3ESRA
//              v0.2a

// Coded by Vaida Bogdan

// 3ESRA consists of a 3 EMA cross + a close above (for longs) the quickest EMA
// or below (for shorts). Note that I've deactivated the RSI Cross Over/Under
// (you can modify the code and activate it). The strategy also uses a stop loss
// that's at 1 ATR distance from the entry price and a take profit that's at
// 4 times the ATR distance from the entry price.

// Feedback:
// Tested BTCUSDT Daily
// 1. Stoch-RSI makes you miss opportunities.
// 2. Changing RR to 4:1 times ATR works better.

//@version=4
