costruzione di classi in mql5

[Joe.Ferry.1972]

Buon giorno a tutti, ragazzi scusate ho un problema che non riesco a risolvere, cioè ho creato un indicatore e vorrei richiamarlo in un expert e non riesco a farlo pur avendo consultato diverse guide e tutorial. Qualcuno può cortesemente spiegarmi come posso risolvere il problema ?
