This copier instantly copies all market orders of another Expert Advisor inverting them – a BUY deal is turned into SELL and vice versa.

The lot size is set using the MultLot multiplier. For example, if your Expert Advisor's initial BUY order size is 1 lot and it is closed in a loss of $200, while Copier's MultLot parameter is 3, the copied SELL order is closed with $600 of profit minus spread. The total profit comprises almost $400.

Pending orders are not copied till they turn into market ones.

The product settings are simple:

• MultLot=2.0 – copied order multiplier;
• Magic = 23646 – copied order magic number;
• CanTrade = true – enable/disable copying deals.
