Why does the price sometimes differ from the underlying market? 

The price of a perpetual future is based on the value of its underlying instrument. Axi acts as principal, so the price you see may differ from the underlying market — this happens through Axi applying its spread to the prevailing bid/offer of the underlying instrument. It can also differ due to market conditions, supply and demand, and liquidity. 

What is funding, and why does it happen? 

Funding is a periodic payment between long and short position holders, designed to help keep a perpetual future's price aligned with its underlying spot/index price. It's a mechanism, not a guarantee — the two prices aren't required to converge or stay equal. Funding is a debit or credit while you hold a position; it is separate from the trading fee charged only when you open or close a position. 

How is the funding rate determined, and who pays whom?

How often is funding applied? 

  • Axi Trading Platform: generally every 8 hours. Some instruments may use a different schedule (e.g., every 4 hours) — check the specific instrument's funding schedule in the platform or Product Schedule. 

  •  MT5: applied in line with standard CFD financing methodology, generally as a single daily adjustment. Rate and timing vary by instrument. 

Worked example (crypto, illustrative only — not live rates) 

Funding is settled three times daily on the Axi Trading Platform: 00:00, 08:00 and 16:00 UTC. 

If BTCUSD is trading at $60,000 and your position size is 0.1 lots: 

  • Position value = $60,000 × 0.1 = $6,000 

  • If the funding rate is 0.1%: funding charge = $6,000 × 0.1% = $6

Always check the current funding rate shown on the platform before or while holding a position. This example is for illustration only and does not reflect live funding rates.
