strategy("Mean Reversion - Envelope Strategy", overlay=true )

// ----------------------- DESCRIPTION -----------------------
// THIS SCRIPT IS A MEAN REVERSION SYSTEM THAT USES A MOVING AVERAGE AS BASE CALCULATION AND A % OF THIS MOVING AVERAGE TO CALCULATE THE ENVELOPE
// BY DEFAULT, THE SYSTEM WILL PLACE LONG ORDERS ON THE MOVING AVERAGE -5% PER ENVELOPE COUNT (5%, 10% AND SO ON...)
// YOU CAN ENABLE THE SHORT ORDERS THAT WILL FOLLOW THE SAME LOGIC ON THE OPPOSITE SIDE
// THE SYSTEM WILL CLOSE EVERY ONGOING TRADE WHEN THE PRICE RETURNS TO THE MEAN
