REX by vitelot

// Best used as an exit indicator at default settings.
// Also doing well in entering positions by using TEMA(14) for REX and SMA(14) as signal.
// You need to tune it yourself according to your trading style.
// Use at your own risk.

版本注释:

// Oct 2019: added zero line;
// also added OS/OB lines based on stddev, though commented out at the moment so to not overload the graph.
