The additional volume commission for trading on MetaTrader 4 platform charged on top of the standard Dukascopy Bank fee schedule has been reduced by 50% to become $0.5 per 1 MT4 lot ($5 per $1 million).
Note that the volume commission on MT4 accounts is calculated for a round turn transaction and is entirely charged on opening trades. Thus, only the positions opened past this news release will benefit from the reduced commission rate.
