Zero Lag MACD è un indicatore che ha fatto la sua prima comparsa con la Metatrader, noi l’abbiamo tradotto per la cTrader ed è stato subito apprezzato
Versione : 1.0.2 ( 16.05.2020 )
Gratis
questo indicatore è stato tradotto per la cTrader dalla versione tanto amata per la Metatrader 4 , in molti ce lo avete chiesto e noi lo abbiamo fatto.
Praticamente è la versione migliorata della versione standard del MACD, il segnale d’ingresso risulta più performante rispetto all’originale ed è per questo che viene utilizzato più degli altri indicatori.
