Sto chiedendo aiuto alla comunità...
MT5
Impossibile eseguire l'ottimizzazione tramite parametri di overshooting su più coppie allo stesso tempo.
Quando seleziono l'opzione "Tutti i simboli da Market Watch" nel tester sotto "Symbol" disabilita la possibilità di impostare l'overshooting dei parametri di input nella scheda "Parameters", semplicemente non vengono spuntate le caselle e non vengono inseriti i valori. Cosa si dovrebbe fare?

Non è stato possibile fare l'ottimizzazione tramite parametri di overshooting su più coppie allo stesso tempo.
Quando seleziono l'opzione "Tutti i simboli da Market Watch" nel tester nella colonna "Symbol" disabilita la possibilità di impostare l'overshooting dei parametri di input nella scheda "Parametri", semplicemente non vengono inseriti tick e valori. Cosa si dovrebbe fare?

non è ottimizzato su alcuni caratteri, appena testato

[Mikhail Tkachev]

Mikhail Mishanin:

non è ottimizzato su più caratteri, appena testato

E deve passare attraverso i parametri per ogni simbolo in un test separato?
Lo stesso in MT4. Quindi la possibilità di testare la multi-valuta in MT5 è un mito?

UPD Tuttavia, la documentazione dice esplicitamente :

Bisogna capire che specificare un simbolo non significa che il tester userà solo questi dati storici. Informazioni su tutti i simboli utilizzati nell'EA, il tester le carica automaticamente.

Cioè si suppone che un simbolo sia selezionato con set di parametri, e il tester applicherà poi questi parametri "a tutti i simboli coinvolti nell'EA ".

MikeZv:

In MT4 allo stesso modo. Quindi il test multivaluta in MT5 è un mito?

.....

Capite la differenza tra le parole "test" e "ottimizzazione"?

[Mikhail Tkachev]

Сергей Таболин:

Capite la differenza tra "test" e "ottimizzazione"?

È un test o un'ottimizzazione carattereper carattere?

[Valeriy Yastremskiy]

Vitaly Muzichenko:

Quindi ha bisogno di sapere sulle posizioni aperte

Aleksandr Egorov, 2021.07.14 18:04

come calcolare la commissione per gli ordini aperti in mt5 per ogni coppia separatamente?

Sì, errore mio. Enumerando le posizioni su ogni coppia)

[Yuriy Vins]

Ciao a tutti, qualcuno sa dove si accende il mirino sul grafico nello strategy tester MT-5 e se c'è proprio?

[Vladimir Karputov]

Yuriy Vins:
Ciao a tutti, qualcuno sa dove è abilitato il mirino sul grafico nello strategy tester MT-5 ed è presente?

Pulsante centrale del mouse (clic sulla rotella di scorrimento)

amici che possono dirmi come impostare un trailing stop,
