In trading, keeping a position open beyond its expiry typically involves rolling over the position to a future date. This process is known as rolling over or renewing a position.

When a position is opened, it is assigned an expiry date, after which it will automatically close. However, if a trader wants to keep the position open beyond its expiry, they can choose to roll it over to a future date.

To roll over a position, the trader needs to take the following steps:

Check the terms and conditions of the trading platform to ensure that rolling over is allowed and the associated costs and fees.

Determine the new expiry date and time.

Contact their broker or use the trading platform to request the rollover.

Pay any applicable fees or costs associated with the rollover.

Once the rollover is completed, the position will remain open until the new expiry date. The trader can then choose to close the position or roll it over again if desired.

It's important to note that rolling over a position can result in additional costs, such as swap fees or spreads, which can affect the overall profitability of the trade. Traders should carefully consider the costs and benefits of rolling over a position before making a decision.
