Strategy total profit is the difference between the starting and current balance. It is calculated for the whole period of trading with Coinmatics.
The trader selects the base coin when submitting his strategy. Further on, the profit will be calculated in that currency.
If the trader selected BTC as his base coin and trades, let’s say, XRP/ETH, then all trading results will be recalculated in BTC with the exchange rate of those currencies to BTC. So the system calculates everything in BTC and then compares the strategy starting value to the current value.
