如何通过Interactive Brokers TWS Java API获得P＆L的交易

Question

有没有办法通过其Java API获得IB TWS特定交易的盈亏（每日和总到日期）？

Answer 1

You can, but not in the way you seem to be asking. All profit and loss in the API is calculated by you until the trade is closed and then you can use the commissionReport method of the wrapper. A commissionReport is sent after every execDetails. API doc

You can always check your statements for previous profits and losses.

The flow is like this.

• place trade and get fill price from execDetails
• get opening commission from commissionReport
• on every tick calculate open position profit, use bid/ask for realism, but it's all forex has anyway
• close trade and get price from execDetails
• get commission from commissionReport again
• calculate closed trade profit/loss
• also note that commissionReport has a field m_realizedPNL you can use, but I've never tried it.

Answer 2

In the TWS v9.72+ API there is a reqPnl method on the EClient which can be used to subscribe to real-time PnL (unrealized and realized) updates for a full portfolio via the associated method on the EWrapper

Additionally, for a single contractID, you can use: reqPnLSingle on the Client.
