What Happens to Your Position When OKX Converts Pre-Market Perpetual to Standard Perpetual?

When a pre-market perpetual contract is converted, your position size, average entry price, and open orders will not be force-closed or canceled by the system. They carry over directly into the converted standard perpetual contract. But "position unchanged" does not mean "risk unchanged" — after conversion, the contract's pricing mechanism, funding rate, and mark price calculation all switch over. That is what you need to check in advance.

What changes and what stays the same during conversion

OKX's rules are clear: during conversion, your position stays the same and open orders remain valid. You do not need to do anything manually. The system handles the conversion in the background.

The conversion condition is: the underlying token has been listed on at least three major spot exchanges, and the market meets OKX's stability requirements for a standard perpetual contract. OKX decides the conversion timing and will announce it in advance.

But after conversion, several key parameters switch over. They directly affect the actual risk of your position:

The funding rate changes from a fixed value to a dynamic value. In the pre-market phase, the premium index is set to 0, and the funding rate is a fixed rate settled every 4 or 8 hours. After conversion, the funding rate returns to the standard formula, and the premium index starts to be calculated dynamically. If your position direction happens to match the market premium direction, you may need to pay a higher funding fee after conversion.

The mark price calculation method changes. In the pre-market phase, the mark price uses the mid-price of the pre-market contract's own bid and ask, clamped between the highest and lowest price limits. After conversion, the mark price switches to the standard perpetual index price calculation method. If your margin ratio is right around a threshold, the switch in mark price calculation may change your margin ratio reading.

The price limit calculation frequency changes from 5 seconds to 200 milliseconds. In the pre-market phase, price limits are calculated every 5 seconds. After conversion, price limits are calculated every 200 milliseconds. This means the probability of trading being paused because the price hits the limit will change after conversion, especially during high volatility periods.

The worst-case branch: the token never lists

Pre-market perpetual contracts have a termination path that standard contracts do not have: if the token project is canceled or seriously delayed (for example, no listing plan within 6 months), the pre-market contract may be delisted directly and will not convert to a standard perpetual.

In this case, OKX will close all positions using a final settlement price. The rules specifically note that this settlement price "may be set to a nominal minimum price," such as the contract's minimum tick size. This means if you hold a position in the pre-market phase and the token never lists, your position may be force-settled at an extremely low price.

This is not a theoretical risk. The pre-market contract rules themselves include this exit clause, and OKX reserves the right to adjust the final settlement price based on market conditions.

What to check before conversion

If you hold a position in the pre-market phase, do these three things after the conversion announcement is published:

First, confirm the conversion time window. OKX's announcement usually gives a time range (such as "07:00 – 08:00 UTC") rather than an exact second. The standard for conversion completion is that "the index remains stable during the conversion period." Within the conversion window, the contract can still be traded, but pricing will gradually move toward the standard perpetual index price.

Second, recalculate your margin ratio. After conversion, the mark price calculation method changes, so your current margin ratio may change at the moment of conversion. If your original margin ratio was already tight, conversion may trigger a margin call or liquidation. OKX also mentions in the announcement that position tiers may be adjusted after conversion based on liquidity and market conditions without further notice.

Third, check your open orders. Open orders remain valid after conversion, but the price limit calculation frequency changes. Your orders may temporarily fail to fill or behave abnormally because of price limit changes. If you do not want to get filled during the conversion window, consider canceling orders in advance.
