//  The body of a candle C-O is divided by H+L to create a body to size ratio.
//  To avoid any noise apply repetitive DEMA smoothing. Finally apply the RSI
//  transformation to create the D_oscillator. The ^NDX OHLC data are used to
//  produce Buy/Sell signals with interesting results for US stocks and the
//  main European indexes. Equity curves seem to be independent of
//  bullish/bearish environment. See also
