Profit/Loss Patsystems returns Total Profit/Loss.
Stop-Limit orders: if the destination exchange supports stop-limit orders, the orders are sent from MultiCharts as stop-limit orders through Patsystems API successfully; if stop-limit type of orders is not supported by the exchange, the stop-limit is emulated; if it cannot be emulated, the order is rejected.
Patsystems does not support Native One-Cancels-Others group. In this case MultiCharts emulates OCO group on its end. Simulated OCO-group means that all OCO orders are sent to the broker, price is monitored by MultiCharts and once one of the orders is filled, other orders from this OCO group are cancelled by MultiCharts. When one of the OCO orders is filled, MultiCharts sends a command to cancel the second OCO order to broker. Note that the second order may also be filled if price reaches its level before the cancellation is processed by the broker (see [[Trading Risks# OCO-Orders Risk|OCO-Orders Risk]]).
