Before the upgrade, LMEX users maintained separate wallets for cross-margin and isolated-margin futures positions. This created friction when moving funds between strategies and required managing multiple wallet balances in parallel.
The Unified Futures Wallet consolidates all futures activity into a single wallet. Isolated futures wallets are closed and all assets transferred automatically — with no loss of funds. The upgrade was designed to:
- Simplify margin management across all futures positions
- Provide a single view of your total futures capital and exposure
- Unlock features that were unavailable in the isolated wallet structure
New Features Unlocked After Upgrade
Isolated Margin Mode: This mode lets you allocate a defined amount of margin to an individual position. If that position is liquidated, only the margin assigned to it is at risk — all other positions in the Unified Wallet are unaffected. This is the primary risk management tool for traders who want a hard cap on the loss from any single trade.
Hedge and Multiple Position Mode with Isolated Position: An extension of Hedge Mode that supports isolated position management within a hedged structure, giving algorithmic traders more granular control over margin allocation per leg.
Conditions Required Before Upgrading
The upgrade is irreversible. Before initiating it, confirm:
- No active positions in any cross or isolated futures wallet (including sub-accounts)
- No open orders in any cross or isolated futures wallet (including sub-accounts)
- No active Futures Grid Trading Bots (including sub-accounts)
If any condition is unmet, the upgrade will fail. Once all conditions are satisfied, navigate to the Futures Wallet page, click Upgrade, read the notices carefully, and confirm.
The process takes approximately three minutes. During this window, futures trading, bot operation, copy trading, and futures wallet transfers are all unavailable.
Critical API Changes: v2.1 → v2.3
This section is the most important for developers and bot operators. Once the Unified Futures Wallet is active, v2.1 API endpoints no longer function. All calls must be updated to the current version, v2.3, before or immediately after upgrade.
1. Version Change
All futures API calls must update the version path:
- Old:
https://api.lmex.io/futures/api/v2.1/order - New:
https://api.lmex.io/futures/api/v2.3/order
2. Symbol Format in Requests
All symbol fields in requests must use the XXX-PERP format:
- Old:
BTC-PFC - New:
BTC-PERP
3. Symbol Format in Responses
All symbol fields in responses now return XXX-PERP:
- Old:
BTCPFC - New:
BTC-PERP
4. Market Field Format in Responses
All market fields now use XXX-PERP-USDT:
- Old:
BTCPFC-USD - New:
BTC-PERP-USDT
5. Wallet Name Format in Responses
Wallet names now use ISOLATED@XXX-PERP-USDT:
- Old:
ISOLATED@BTCPFC-USD - New:
ISOLATED@BTC-PERP-USDT
6. Quote Currency in Responses
The quote currency field in responses changes from USD to USDT.
The full API change log is documented at docs.lmex.io.
Sub-Account Behaviour
The upgrade applies universally — the master account and all sub-accounts are upgraded simultaneously. There is no option to upgrade only the master account while leaving sub-accounts on the old wallet structure. All historical wallet data from before the upgrade remains accessible in the Futures Wallet History section.
If the Upgrade Fails
Verify all three pre-conditions: no open positions, no open orders, no active bots — across all sub-accounts. If conditions are met and the issue persists, contact LMEX support.
