GMX vs dYdX

GMX direct markets run on Arbitrum, Avalanche and MegaETH. GM and GLV pools provide the assets that back trading. A keeper executes orders using valid Chainlink price inputs and on-chain market rules.

dYdX runs perpetual markets on dYdX Chain. Makers add orders to a central limit order book and takers cross existing liquidity. Fee tiers and market parameters are governed by the dYdX community.

A GMX trader does not inspect a conventional bid-and-ask book. The confirmation shows the relevant oracle side, expected position fee, net price impact, acceptable price and available market capacity.

A dYdX trader can inspect resting bids and asks. A maker order adds liquidity when it rests on the book, while a taker order fills against available depth. A post-only option can prevent a limit order from crossing immediately.

Pool capacity and order-book depth fail in different ways. A GMX order can be limited by pool liquidity, open-interest caps or price impact. A dYdX market order can move through several price levels when book depth is thin.

Most GMX position operations currently use a 0.04% fee when the trade improves long/short balance and 0.06% when it worsens balance. Borrowing, funding, execution and price impact can change the full cost.

dYdX uses maker and taker fee tiers based on a trader's trailing 30-day volume across perpetual order books. The current rate for a wallet is displayed in the dYdX portfolio interface. Governance can adjust the fee schedule.

A maker rate should not be compared directly with a GMX position fee without also comparing fill probability, spread, price impact, funding and any GMX borrowing charge.

GMX adaptive funding transfers value between the long and short sides. Only the larger open-interest side currently pays the separate borrow fee. Both rates can change while a position is open.

dYdX funding is credited or debited through fixed protocol epochs and is intended to keep the perpetual market aligned with its index. Funding parameters are part of the governance-adjustable perpetual module.

For either venue, a low opening fee can be outweighed by holding cost. Compare the current rate direction and the intended duration before opening.

GMX uses wallet-connected contract access. Direct positions run on the selected GMX deployment, while GMX Account positions settle on Arbitrum.

dYdX trading uses accounts and subaccounts on dYdX Chain. The chain has its own validators, governance parameters and bridge paths. Trading fills generally do not require a separate gas payment from the trader under the default interface model, although chain transactions and transfers can have their own costs.

Neither design removes protocol, oracle, governance, bridge or liquidation risk. The relevant dependency set is different.

GMX supports market, limit, stop, take-profit, stop-loss and TWAP actions. Trigger conditions do not guarantee execution because a keeper still needs valid prices, liquidity and acceptable on-chain conditions.

dYdX supports order-book controls such as maker, taker, reduce-only and different order durations. A resting limit may not fill, while a market order can receive a worse average price during thin liquidity.

Liquidation can consume substantial collateral on both venues. A stop-loss is a risk-control instruction, not insurance against price gaps, chain issues or failed execution.

GMX may fit a trader who prefers pool-based execution and wants a quote without managing a resting book. That trader must understand oracle sides, keeper execution, price impact, borrowing and funding.

dYdX may fit a trader who wants a visible order book, post-only maker orders and a volume-based fee structure. That trader must understand dYdX Chain accounts, book depth, funding and chain-specific risk.

The better choice can change by asset and order size. Compare the live market rather than relying on an exchange-wide verdict.
