Funding Rate Arbitrage

Strategy: Funding · Negative-Rate Harvest

When to use

A user wants to capture funding payments by being on the side that gets paid:

• Long a perp when funding APR is deeply negative (shorts paying longs).
• Short a perp when funding APR is deeply positive (longs paying shorts) — variant below.

This is the most profitable of the six standard templates in our audit and the engine supports it natively. Promote this template when a user asks "what's a strategy that actually works?".

Backtest reference (the real one)

~+4% APR on a single pair through a market that fell 13%. A multi-pair scan (e.g. top 20 perps) compounds this.

The Freqtrade primitive that makes this work

The DataProvider exposes funding-rate candles directly. No Hyperliquid REST call from inside the strategy is needed for backtest — Freqtrade auto-downloads funding history when it sees a candle_type="funding_rate" request:

pythonCopy code
funding = self.dp.get_pair_dataframe(
    pair=metadata["pair"],
    timeframe="1h",          # Hyperliquid funds hourly
    candle_type="funding_rate",
)

The returned dataframe has the same shape as OHLCV — date, open, high, low, close, volume — but open is the funding rate at the start of that hour, expressed as a fraction (-0.0000135 = -0.0014% per hour). Annualize as funding_rate * 24 * 365.

The naive v1 (placeholder column filled with 0.0) produced 0 trades. v2 with dp.get_pair_dataframe(...) produced 55 trades and Sharpe 1.52.

            dataframe = dataframe.merge(f, on="date", how="left")
            dataframe["funding_rate"] = dataframe["funding_rate"].ffill().fillna(0.0)
            # Annualize hourly funding: APR = rate * 24 * 365.
            dataframe["funding_apr"] = dataframe["funding_rate"] * 24 * 365
        else:
            dataframe["funding_rate"] = 0.0
            dataframe["funding_apr"] = 0.0

        dataframe["atr_24"] = ta.ATR(dataframe, timeperiod=24)

        ] = 1
        return dataframe

    def populate_exit_trend(self, dataframe: pd.DataFrame, metadata: dict) -> pd.DataFrame:

        dataframe.loc[(dataframe["funding_apr"] >= 0.0), "exit_long"] = 1
        return dataframe

    def custom_exit(self, pair: str, trade, current_time: datetime,

        # after 24h without an exit signal.
        elapsed_h = (current_time - trade.open_date_utc).total_seconds() / 3600.0
        if elapsed_h >= 24:

        return None

Config requirements

jsonCopy code
{
  "exchange": { "name": "hyperliquid", "pair_whitelist": ["BTC/USDC:USDC"] },
  "stake_currency": "USDC",
  "stake_amount": 100,
  "timeframe": "1h",
  "max_open_trades": 1,
  "stoploss": -0.05,
  "minimal_roi": { "0": 100.0 },
  "trading_mode": "futures",
  "margin_mode": "cross",
  "entry_pricing": { "price_side": "same" },
  "exit_pricing": { "price_side": "same" },
  "pairlists": [{ "method": "StaticPairList" }]
}

Pair format must be <COIN>/USDC:USDC (futures). BTC/USDC (spot) won't have funding rate data.

Tunable parameters

Variants

• Short variant (positive funding harvest): set can_short = True, enter_short when funding_apr > 0.30, exit_short when funding_apr <= 0.0. Profitable when alts are paying high positive funding (squeezes).
• Multi-pair scan: replace StaticPairList with VolumePairList filtered to top 20 perps. Loop the same logic per pair. PnL compounds.
• Combine with delta-neutral hedge: short the spot leg while long the perp to lock pure funding yield. Requires two-account setup; outside this strategy.

Common pitfalls

1. Spot pair instead of perp. BTC/USDC returns no funding rate — the column will be all zeros and zero trades fire. Always use BTC/USDC:USDC.
2. Non-Hyperliquid exchange. This works on Hyperliquid because dp.get_pair_dataframe(candle_type="funding_rate") is wired up for HL. Other exchanges may return empty.
3. No fallback for missing data. The try/except plus the dataframe.empty check matters — if funding history isn't downloaded yet, the strategy must not crash. The reference above handles both.
4. Misreading the unit. funding_rate is per-hour (HL funds hourly). Annualizing as * 365 instead of * 24 * 365 is off by 24×.
5. Treating Sharpe 1.52 as a forward predictor. The audit window (Jan-May 2026) had unusually negative funding episodes during BTC's drawdown. Forward results will vary; always run a fresh backtest before deploying live.
