Supported Exchanges
CexDex works with the following DEX derivatives exchanges:
| Exchange | Network | Website |
|---|---|---|
| Paradex | StarkNet (L2 Ethereum) | paradex.trade |
| Hyperliquid | Hyperliquid L1 | app.hyperliquid.xyz |
| Lighter | Arbitrum | lighter.xyz |
| Omni | Omni Network | omni.trade |
| AsterDex | BNB Chain | asterdex.com |
| EdgeX | EdgeX Chain | edgex.exchange |
| Extended | StarkNet | extended.exchange |
| Nado | Nado Chain | nado.trade |
Data Update Frequency
CexDex receives data from each exchange at different speeds — depending on whether the exchange supports WebSocket or REST API only.
Bid/ask prices and funding rates in the system are the last received values, not guaranteed execution prices. Time passes between the update and the moment a position is opened. The higher the update delay, the higher the risk of execution at prices that have already changed.
Bid/Ask (entry price)
| Exchange | Method | Delay |
|---|---|---|
| Lighter | WebSocket delta | ~50 ms |
| Extended | WebSocket delta | real-time |
| Nado | WebSocket | real-time |
| AsterDex | REST polling | ~10 sec |
| Omni | REST polling | 15–30 sec |
| EdgeX | REST polling | ~30 sec |
| Paradex | WebSocket batch | ~40–45 sec |
| Hyperliquid | REST polling | 30–60 sec |
Funding Rate
| Exchange | Update delay | Model | Accrual interval |
|---|---|---|---|
| AsterDex | 3 sec (WebSocket) | Discrete | 1h / 2h / 4h / 8h (depends on instrument) |
| Nado | ~20 sec (WebSocket) | Discrete | 1 hour |
| Lighter | ~10 sec (REST) | Discrete | 1 hour |
| Extended | ~10 sec (REST) | Discrete | 1 hour |
| Paradex | ~40–45 sec (WebSocket batch) | Continuous | every second |
| Omni | 15–30 sec (REST) | Discrete | 1h / 2h / 4h / 8h (depends on instrument) |
| Hyperliquid | 30–60 sec (REST) | Discrete | 1 hour |
| EdgeX | ~30 sec (REST) | Discrete | 4 hours |
What the System Does Not Do
CexDex is a tool for monitoring and finding arbitrage opportunities. It does not replace liquidity analysis before entry:
- Does not show order book depth — only the best bid and ask, without volume at levels
- Does not analyze liquidity for large positions
- Does not guarantee execution price — the actual price is determined by the exchange at the moment the order is opened
- Does not warn about sharp movements between updates
Before opening a position — open the order book on the exchange and make sure the volume at the best levels is sufficient for your size. This cannot be delegated to the system.
