Of course, this is just a strategy to find an account when the accounts with denominated currencies are comparable in exchange rates. 0 (rates at the time of writing). This should fulfill the strategy of the account with the maximum available margin; however, it will fail miserably, if for example, one of the currencies is JPY instead of EUR. 0, this is not ideal as most of the time the JPY account will be picked. getAmountAvailableRatio() >= baseTradingConfig. getNetAssetValue() >= baseTradingConfig.
