Updated Maximum Position Sizes (NMax) For Perpetual Futures
 
We have reviewed and updated the maximum position size (NMax) parameters across our perpetual futures to better reflect current market liquidity.
Most NMax values have increased.
Altcoin perpetuals have the largest increases. Most clients can expect larger position size limits and more favourable margin requirements.
A small number of instruments have decreased their maximum position size. Clients holding substantial PAXG positions may see a modest increase in their margin requirements.
These changes apply to Standard Margin accounts only. No liquidations are expected.
 
The updated values take effect on Thursday, 24 September 2026 at 09:00 UTC.
