per favore aiutatemi a mettere la freccia di acquisto e di vendita su questo codice. - pagina 2

Vladimir Karputov 2015.11.07 17:34 #11

Suggerisco di fare i compiti: nella funzione OnDeinit() scrivere il codice che rimuove tutti gli oggetti OBJ_ARROW_UP e OBJ_ARROW_DOWN.

Forum sul trading, sistemi di trading automatico e strategie di trading di prova

per favore aiutatemi a mettere la freccia di acquisto e di vendita su questo codice.

Karputov Vladimir, 2015.11.09 13:36

Controlla la cartella "Progetti" in MetaEditor.

P.S. Per l'ottimizzazione è necessario limitare il numero di barre per disegnare le frecce.

Ma non sarà oggi.

Allega il file della versione "1.04".
