# Risk Mitigation Measures

1. PnL is capped at 2% of insurance pool size, assuming current insurance pool size is $1,000,000, any position's PnL is capped at $20,000
2. Opened position can only be closed after a period of time.
3. Account based limit on open interest
4. Dynamic trading fee rate, this works similar to slippage in an orderbook based perps exchange, if an open or closure of a position will cause OI ratio more skewed, a higher fee rate will be applied, read more in [trading fee rates](/ot/perpetuals-trading/trading-fee-rates.md)
5. Funding fee: long pays short if long OI > short OI, short pays long if short OI > long OI.
