GMX Position Manager

WHAT IT DOES

GMX Position Manager lets you trade on GMX perpetual markets directly from your wallet. Enter the GMX market contract address, your collateral amount, position size (USD), leverage (x1–x100), and direction (long/short). Choose your action—open, close, or adjust a position. The tool reads the current oracle price, calculates position value, margin ratio, estimates liquidation price, and displays a full position preview. Once confirmed, it encodes the transaction and submits it via your wallet's signer. No separate UI, no manual ABI encoding—just fill in your parameters and trade.

HOW TO USE

Connect your EVM wallet using the BotGentz wallet bridge. Select the network (Arbitrum recommended for GMX). Paste the GMX market contract address into the input field. Enter your collateral in ETH, position size in USD, leverage (e.g., 5 for 5x), and select direction (Long or Short). Choose your action (Open, Close, or Adjust). The preview shows your position value, margin ratio, estimated liquidation price, and required collateral. Click "Review & sign" to confirm and submit the transaction. The tool reads the oracle price, encodes the function call, and sends it via your wallet.

TECHNICAL MECHANISM

The tool uses the injected BGWallet bridge to access the EVM provider via ethers.js v5.7.2. It builds a contract interface with GMX market functions: openPosition(bool isLong, uint256 collateral, uint256 size, uint256 leverage), closePosition(uint256 positionId), adjustPosition(...), and getOraclePrice(). The getOraclePrice view function is called via eth_call to display the current oracle price before submission. The user's collateral is converted to wei using ethers.utils.parseEther. The transaction is encoded using ethers Interface.encodeFunctionData. For open positions, the collateral is sent as the transaction value. Gas estimation is performed with a 20% buffer. The signed transaction is sent via the wallet's signer, and the receipt is monitored for confirmation.

WHAT IT CANNOT SEE

This tool cannot predict future price movements—GMX positions are directional bets with real risk. It cannot guarantee liquidation avoidance—prices can move against your position rapidly. It cannot account for changes in funding rates between transaction submission and execution—funding can change at any time. It cannot detect off-chain oracle manipulation. It cannot verify GMX market contract legitimacy without user confirmation—always check the contract address. It cannot simulate complex position combinations—this tool handles single positions only. It does not track your open positions or provide portfolio management.

PLEASE NOTE

EVM chains only—Arbitrum is the primary chain for GMX. Position trading involves significant risk. This tool is free to use but requires a wallet connection and pays gas fees for transactions. Always verify the market contract address independently. The oracle price is read at the moment of preview—actual price may vary at execution. This tool is informational and does not provide financial advice.
