Multiple lines for 1 transaction

Hello,

I bought 82 AXS (in one time) to make a test.
Why, for this request “/fapi/v1/userTrades”, my long position is divided in 8 lines, and not in one?

Thanks in advance

The /fapi/v1/userTrades endpoint returns a list of trades not positions.

When the order 2636657424 was placed, the exchange matched with multiple other orders eligible to fill your request. It is not always the case that an order is filled with just one trade, it is possible and expected for an order to contain multiple trades especially if the order position is relatively large.

To retrieve account positions for futures, use the /fapi/v2/positionRisk endpoint. (https://binance-docs.github.io/apidocs/futures/en/#position-information-v2-user_data)
