//@version=4

// This is a simple crossover Moving Average strategy, good for long term crypto trades. 
// It buys when the MA "X" crosses up the MA "Y", viceversa for shorts. 
// Both MAs are selectable from the Inputs section in the front panel. 
// There is also a Position Management option thats 
// sizes positions to have the same USD risk (using leverage) on each trade,
// based on the percentage distance to the stop loss level.
// If you turn this option on you will see how the profit 
// grows exponentially while the drawdown percentage almost remains the same.
