Below are the proposed range and initial fees for testing; a final range should be confirmed by governance closer to full deployment:
Increase / Decrease Position:
Price Impact:
Swap Fees:
Funding Fee
Borrow Fee
Multiplier Value
GMX V2 contracts combine a proposed lower swap fee with the implementation of price impact (both positive and negative) along with oracles that aggregate best bid and best ask pricing from the reference exchanges. This setup is aimed to ensure deep liquidity is secured with liquidity providers having a less volatile exposure, as net OI will be more effectively balanced through economic incentives when a large directional exposure occurs.

In GMX V2, swaps are now a two-step process similar to increase/decrease position transactions. This setup greatly reduces toxic flow (as was seen when GMX moved to two-step transactions) and should allow lower fees, which combined with price impact, will create efficient markets without running into front-running issues. This would make it convenient for traders to swap in and out of different collateral when increasing or decreasing positions. The lowered swap fee may also help make the protocol a preferred platform for swaps once aggregators can integrate this novel approach (discussions are already ongoing).
