Lock mode
The lock mode controls whether multiple orders on a single currency will be grouped together or occur separately. Opened positions are orders that are currently being performed. Each position opens in units of the base currency i.e. the currency that stands in the beginning of quotation sign. Volume of position can be changed to this unit and marked as “Volume 1”. If there is an opened position on one currency pair with the volume V1, and the client opens one additional position on the same currency pair, but opposite directions, then the result will depend on lock mode that was set while opening this position. This mode will be active only at the moment of order execution. Positions that are already opened do not have such an opportunity.
If the Lock mode is not selected, then, during the opening of an additional position in the same currency (opposite directions), the volume of the second position will be added to the first one and the position of sum volume will appear.
If Lock mode was set, then during the opening of an additional order in the same currency pair, a second position will be created and it will not be grouped with the first one. |
