While it is possible to have multiple investments in both different and in the same strategy, one investment does not affect the other in any way.
Each investment has its own invested funds, copying coefficient, and copied orders. Profits made on a respective investment will be used for the calculation of the commission to be paid to the strategy provider for copying the strategy.
For investments within the same strategy, an investment will start from the point of time when the investment was opened. It could be that one investment will be profitable, while the other suffers a loss at the same time. Both investments will have separate and unrelated calculations nonetheless.
