Buonasera Nicolas, avevo già verificato l’indicatore RMI che mi hai inviato e che era già disponibile. Quello che ho chiesto io è diverso a mio parere, da un risultato che presenta oltre al RMI una signal lenght (6). Non le risulta? Mi è fondamentale per usare questo indicatore

Grazie per la risposta

Prova questa versione modificata, dove, oltre al segnale RMI è stata aggiunta una sua media (segnale) ed un RSI.

Le linee che non t’interessano puoi renderle invisibili tramite le proprietà dell’indicatore:

la terzultima riga è quella che io ho modificato secondo l’interpretazione che ho rilevato dal sito indicato. Se preferisci puoi commentarla e togliere i commenti da quella ancora più sopra ed usare quella formula (che è il codice che hai postato).
