Futures contract rollover
Futures Contract Rollover
A futures contract rollover is a crucial concept for traders engaging in futures trading, particularly in the dynamic world of cryptocurrency futures. It refers to the process of closing out a near-expiration futures contract and simultaneously opening a new position in a further-dated contract for the same underlying asset. This article will explain why rollovers are necessary, how they work, and what factors traders should consider.
Why Rollover?
Futures contracts have a predetermined expiration date. Once this date is reached, the contract ceases to exist. To maintain continuous exposure to the underlying asset—like Bitcoin or Ethereum—traders must "roll" their position forward. Without rollover, a trader would have to physically settle the contract (taking or delivering the underlying asset), which is often impractical, especially with cryptocurrencies. Rollover allows traders to maintain a continuous long position or short position without actually taking delivery of the asset.
How Does Rollover Work?
The rollover process typically involves two simultaneous actions:
1. Closing the Expiring Contract: The trader sells (if they were long) or buys (if they were short) the expiring futures contract. 2. Opening the New Contract: Simultaneously, the trader buys (if they were long) or sells (if they were short) a futures contract with a later expiration date.
The goal is to maintain the same market exposure with minimal disruption. However, the price difference between the expiring and the new contract—known as the basis—can impact the rollover process.
Understanding the Basis
The basis is the difference between the futures price and the spot price of the underlying asset. This difference is influenced by factors like:
- Cost of Carry: Includes storage costs, insurance, and financing charges (less relevant for crypto).
- Convenience Yield: The benefit of holding the physical asset (also less relevant for crypto).
- Market Expectations: Anticipated future price movements.
When the futures price is higher than the spot price, it's called contango, and rolling over usually involves a cost. When the futures price is lower than the spot price, it's called backwardation, and rolling over can potentially result in a profit.
Rollover Dates & Considerations
Rollover doesn’t happen randomly; it typically occurs a few days before the expiration date of the current contract. Exchanges designate specific rollover dates. These dates are often crucial for volume analysis as they can lead to increased trading activity.
- Rollover Gap: The difference in price between the expiring and the new contract can create a “rollover gap.” This gap can be influenced by market sentiment and order flow.
- Liquidity: The new contract might have different liquidity than the expiring contract. Lower liquidity can lead to wider bid-ask spreads and increased slippage.
- Funding Rates: In perpetual futures contracts (a related concept), funding rates are a constant factor influencing profitability. Understanding these rates is crucial for long-term trading strategies.
- Contract Specifications: Always verify the contract specifications of both the expiring and new contracts, including contract size and tick value.
Strategies for Rollover
Several strategies can help mitigate the risks associated with rollover:
- Gradual Rollover: Instead of rolling over the entire position at once, traders can roll over a portion of their position each day leading up to the rollover date. This helps to average out the basis difference. Dollar-Cost Averaging principles can be applied here.
