// This is one of the techniques described by William Blau in his book
// "Momentum, Direction and Divergence" (1995). If you like to learn more,
// we advise you to read this book. His book focuses on three key aspects
// of trading: momentum, direction and divergence. Blau, who was an electrical
// engineer before becoming a trader, thoroughly examines the relationship 
// between price and momentum in step-by-step examples. From this grounding,
// he then looks at the deficiencies in other oscillators and introduces some
// innovative techniques, including a fresh twist on Stochastics. On directional 
// issues, he analyzes the intricacies of ADX and offers a unique approach to help 
// define trending and non-trending periods.
// Blau`s indicator is like usual MACD, but it plots opposite of meaningof
// stndard MACD indicator. 
//
// You can change long to short in the Input Settings
// Please, use it only for learning or paper trading. Do not for real trading.
