Buongiorno,

gradirei testare questo indicatore che pur stand alone , viene utilizzato in abbinamento all’indicatore Alligator sempre di Williams (presente nella libreria PRT).

Grazie per il consueto aiuto.

// Bill William Bull/Bear divergent bars
// See: Book, Trading Chaos by Bill Williams
//
// Coded by polyclick
//
// A bullish (green) divergent bar, signals a trend switch from bear -> bull
// -> The current bar has a lower low than the previous bar, but closes in the upper half of the candle.
// -> This means the bulls are pushing from below and are trying to take over, potentially resulting in a trend switch to bullish.
// -> We also check if this bar is below the three alligator lines to avoid false positives.
//
// A bearish (red) divergent bar, signals a trend switch from bull -> bear
// -> The current bar has a higher high than the previous bar, but closes in the lower half of the candle.
// -> This means the bears are pushing the price down and are taking over, potentially resulting in a trend switch to bearish.
// -> We also check if this bar is above the three alligator lines to avoid false positives.
//
// Best used in combination with the Bill Williams Alligator indicator.
