On this help page, we explain the automatic adjustment known as "Flipped transaction".
1. What is an "Flipped transaction"?
Flipped transaction is an automatic adjustment that occurs in trading instruments—such as bitFlyer FX or futures—where short‐selling positions are allowed. This is not an error; it simply indicates that the system has automatically adjusted your positions. No action is required on your part, and rest assured that profit and loss have been properly calculated.
2. Example
Specifically, the system notifies you when your position reverses direction—i.e. from long to short or from short to long—in a single transaction.
Take the following example using Bitcoin futures:
As of January 6, 2022, you opened a short position of 1 BTC.
On January 16, 2022, you place an order to go long with 2 BTC.
The system handles this by closing the 1 BTC short position and opening a new 1 BTC long position—thus splitting the trade into one close and one open long.
