1
Confirm direction and timing
First confirm which side receives funding and which side pays. Then confirm the next funding time and whether both exchanges use the same interval. A large rate is less useful if the payment is far away or likely to change.
- Identify the receiving side and the paying side.
- Check the next funding time on each exchange.
- Compare funding intervals so the payments line up.
2
Confirm the same asset and contract
Both legs must be the same underlying asset and compatible contract type. Mismatched settlement currency or contract design can quietly change the real risk of the position.
- Same underlying asset on both legs.
- Compatible contract type and settlement currency.
- No hidden difference in how the contract is priced.
3
Check execution
Compare entry spread, order book depth and realistic size. If the book cannot support your size, expected funding can be smaller than the slippage cost. Include taker fees, possible maker fees and the cost of closing later.
- Depth must support your intended size on both legs.
- Entry spread should not already eat the funding edge.
- Count taker fees, maker fees and the exit cost.
4
Set size, leverage and exit
Finish with risk. Keep leverage low, confirm liquidity on both venues, note any deposit, withdrawal or maintenance warnings, and prepare a clear exit if the spread widens.
- Keep leverage low enough to survive divergence.
- Confirm no deposit, withdrawal or maintenance warnings.
- Prepare the exit plan before opening.
