UN EA BASATO SU BANDE B E LARGHEZZA B, BISOGNO DI AIUTO URGENTE!

Alain Verleyen 2013.04.10 18:03 #11

surubabs:

Scusa qualche errore di ortografia,

Voglio la larghezza della banda per questo ha bisogno di qualche calcolo come

Larghezza=(banda superiore-bassa)/banda base

è possibile fare questo calcolo all'interno dell'ea?

Come definirlo? Quando ho provato ho ottenuto un errore,

Width[]=(Upperband[ ]-Lowerband[ ])/Baseband[ ],

per favore consigliatemi

Mostrate il codice reale di ciò che state cercando, per favore.

Perché non hai letto la documentazione? MathMax e MathMin prendono solo 2 argomenti.
Cos'è out=(inputs,weight);?

Ho cercato di capire la documentazione delle funzioni matematiche, ma non sono riuscito a trovare quella giusta perché non so quale dovrei usare.

Ho provato uno per uno le ultime ore, puoi mostrarmi il metodo giusto?

Il metodo giusto per fare cosa?

Kourosh Hossein Davallou 2013.04.11 13:59 #16

Ciao

Lafunzione MathMax restituisce il valore massimo di due valori.

 double x_max=MathMax(iBBMidle[ArrayMaximum(iBBMidle)],iBBUp[ArrayMaximum(iBBUp)]);

La funzione MathMin restituisce il valore minimo di due valori.

 double x_min=MathMin(iBBMidle[ArrayMinimum(iBBMidle)],iBBUp[ArrayMinimum(iBBUp)]);

Sì, hai ragione,

quello che voglio fare è iBBUp-IBBLow/iBBMiddle,

poi il nome era la larghezza, i valori ritornano alla larghezza, se il valore aumenta ex: width>0 un buy open(upside break out), width<0 un sell open(down side breakout).

Non conosco il codice esatto come implementarlo.

Sto provando a codificarlo con il metodo di rete nurale.
