Question 1

Which exchange has the highest SIREN funding rate right now?

Accepted Answer

Bybit shows the highest SIREN funding at +145.60% annualized. A high positive rate means shorts get paid, so this is the venue to short SIREN when running a funding-arbitrage pair. Rates change every settlement window — check the live screener for the current value.

Question 2

Which exchange is best to long SIREN for funding?

Accepted Answer

LBank has the lowest SIREN funding at +10.96% annualized, which makes the long leg cheapest (or paid). Pair it with the highest-funding venue to capture the spread delta-neutral.

Question 3

What is the best SIREN funding-arbitrage pair?

Accepted Answer

The widest spread is long Binance Futures / short Bybit at about 134.7% APR before costs. Verify it in the ORBIT backtester, which subtracts real fees and slippage, before sizing a position.

Question 4

How often does SIREN funding settle?

Accepted Answer

SIREN funding settles every 4h. Longer intervals concentrate the same annualized rate into fewer, larger payments. ORBIT normalizes every venue to a common APR so they are directly comparable.

Question 5

Is SIREN funding positive or negative?

Accepted Answer

SIREN funding is currently positive across venues (longs pay shorts), ranging +10.96% to +145.60% APR.

Question 6

What is the current SIREN perpetual swap funding rate?

Accepted Answer

The current SIREN perpetual swap funding rate ranges from +10.96% to +145.60% annualized depending on the exchange — LBank is lowest and Bybit is highest right now. There is no single SIREN funding rate: every venue runs its own funding formula and order book, which is why the rate has to be read by exchange rather than as one number.

Question 7

What is the aggregated SIREN funding rate across exchanges?

Accepted Answer

Aggregated across the 14 venues ORBIT tracks, SIREN funding currently spans +10.96% to +145.60% APR, a spread of 134.7 percentage points. An aggregated average hides the part that matters for trading — the gap between the cheapest and dearest venue — so the table above lists each exchange separately.

Question 8

How do I read the SIREN 8h funding rate versus the annualized rate?

Accepted Answer

SIREN does not settle on an 8-hour schedule on the venues tracked here. Because intervals differ by exchange, comparing raw per-payment rates is misleading; ORBIT normalizes each venue to annualized APR so the numbers are directly comparable.
