About Mark Price:

Mark Price During Pre-Market Trading

The formula for mark price during pre-market trading of perpetual futures contracts is as follows:

Mark Price = Average of trading prices over the past 10 seconds, calculated every second

If there are fewer than 21 trades in the past 10 seconds, the average of the most recent 20 trades of this pre-market contract will be used.

The mark price will be subject to a ±0.5% price limit, meaning the mark price change per second interval cannot exceed ±0.5%. This price limit applies during pre-market trading and the transition period from pre-market trading to standard contracts.

Transition Period from Pre-Market Trading to Standard Contracts

When BiyaPay can obtain stable index prices in the spot market, pre-market perpetual contracts will gradually convert to standard perpetual contracts. The transition duration depends on price volatility and index price stability. During the transition period, the mark price of pre-market trading will gradually converge to the mark price of standard perpetual contracts, with the formula as follows:

Mark Price = Median (Price 1, Price 2, Contract Price)

During the transition period, trading functions remain unaffected, and pending orders and positions will not be cancelled.

Mark Price After Pre-Market Trading Ends

After pre-market trading ends, the mark price formula is as follows:

Mark Price = Median (Price 1, Price 2, Contract Price)

About Funding Rate:

The funding rate consists of two components: interest rate and premium. BiyaPay uses a fixed interest rate, with the default rate fixed at 0.03% per day. Since there is no premium index during pre-market trading, the funding rate for each settlement cycle of pre-market trading contracts will consistently be 0.005% (funding fee settlement frequency is every 4 hours). BiyaPay reserves the right to adjust interest rates from time to time based on market conditions.

After pre-market trading ends, when the premium index becomes available, the funding rate will follow standard contract funding rate rules, where the maximum and minimum funding rates can reach +2.00%/-2.00%.

Leverage and Margin Tiers:

Maximum Leverage Position Size (USDT Notional Value) Maintenance Margin Rate
5x 0 < Position ≤ 5,000 10.00%
4x 5,000 < Position ≤ 10,000 12.50%
3x 10,000 < Position ≤ 30,000 16.70%
2x 30,000 < Position ≤ 80,000 25.00%
1x 80,000 < Position ≤ 200,000 50.00%

  • Please note that during pre-market trading and the transition period from pre-market trading to standard contracts, BiyaPay will implement stricter maximum prices.
  • BiyaPay may implement price limits on mark prices during pre-market trading and the transition period from pre-market trading to standard contracts;
  • When the trading pair launches on the spot market, pre-market trading will end and be converted to standard perpetual contracts without separate announcement;
  • When the above perpetual contract launches, its funding rate limits are +2.00% / -2.00%;
  • Funding fees are settled every four hours;
  • Based on market risk conditions, BiyaPay may adjust the above contract parameters, including funding rates, minimum price increments, maximum leverage, initial margin, maintenance margin, and other important parameters;
