API usage is rate limited to 1 request per second by default; higher limits are available by request via [support@ondoperps.xyz](mailto:support@ondoperps.xyz). * **Maximum position size raised to \$1,000,000** per market, per account (previously \$500,000). **Documentation updates** * **Public Beta:** documented the Tokenized Stock Collateral beta parameters: per-asset collateral caps, the 30% maximum allowed USDC Debt, and the \$100,000 USDC Debt cap per account. * **Funding Your Account:** published per-asset collateral caps (146 SPYon, 166 QQQon). * **Fees:** clarified fee mechanics: fees are charged in USDC per fill and deducted from your USDC balance, separate from position PnL. * **Funding Rates:** clarified that funding payments are credited to or debited from your USDC balance. * **Collateral Management:** corrected the Maximum Allowed Debt formula to `min(Non-USDC Margin Value x 30%, $100,000)`. * **Settlement:** documented that Auto-Exchange also triggers at the \$100,000 USDC Debt maximum, and clarified the difference between Auto-Exchange and liquidation. Auto-Exchange sells only enough collateral to cover the debt. * **Withdrawals:** published the exact withdrawal model, including how unrealized PnL and USDC Debt affect what you can withdraw. * **Weekend Mechanics:** stated the closed-market settlement fee (currently 2.5% of the debt repaid). * **Measuring Risk:** noted that with tokenized stock collateral, a decline in collateral price can raise your Margin Ratio on open positions.
