How Closing a Futures Position Transfers Exposure
Summary
The document explains how closing a futures or perpetual futures position changes a trader’s net exposure. A trader closes a long by selling the contract, which opens or increases a long position for whoever buys it. The original short position remains open; the closing trade does not erase it. The same mechanics apply to regular futures and perpetual contracts.
The answers describe the exchange as a central counterparty that nets trades, and use a simple example: after the original long sells to close, the first counterparty remains short while the buyer on the closing trade is long. The exchange’s aggregate exposure is balanced. This addresses the question of who may take the other side when the original counterparty later closes. The explanation is conceptual and does not cover venue-specific settlement, margin, or liquidation procedures.
Key ideas
- Closing a long futures position requires selling the contract to another market participant.
- The closing trade offsets the seller’s exposure but does not cancel the original short position.
- The new buyer becomes long and may later close by selling to another participant.
- The described position-transfer mechanics apply to regular futures as well as perpetual contracts.

# What happens to the perpetual future counterpart when my position is closed? (BINANCE FUTURES) # What happens to the perpetual future counterpart when my position is closed? (BINANCE FUTURES) As far as I understand, perpetual contracts are like regular futures except they can be held open indefinitely. However, I don't know about any other brokers out there, but in Binance, when you open a perpetual contract, you do so by interacting with an order book, meaning, for every position you open there is an opposite position held by another person (your counterpart). Now this is when my understanding gets a bit fuzzy. Correct me if I'm wrong, but I believe the contract is an agreement to perform a transaction at a pre-defined price, somewhere in the future. So... what happens to my counterpart if I close my position, or get liquidated? I mean, if my position, (let's say, a long), gets closed, then who is going to be there to fulfill my counterparts' short position when he closes his? Does this issue happen with regular futures as well? ## Answer by SuavestArt (score 4, accepted) https://quant.stackexchange.com/a/71571 Yes, it also work like this for regular futures contracts. Say you've an open long position in that contract. In order to close it (open a short position so as to get net zero exposure), you'll need someone to go long that same contract. Since the counterparty for all trades is the exchange (Central Counterparty or CCP), the final exposure for each party would be: You: net zero (long position + short position) Your first ctpy: one short position Your second ctpy: one long position CCP: net zero (two long positions + two short positions) So your original long position doesn't disappear when you close it. ## Answer by dm63 (score 3) https://quant.stackexchange.com/a/71570 The only way you can close out your long is by selling it on the order book. When this happens, another investor takes the long. That person is now on the other side of the short position. This dynamic is the same as for regular futures.
