Hummingbot fee rebate 2026: the market-maker setup that pays you back

Hummingbot is free, open-source and self-hosted, so it charges you nothing — every cost goes to the exchange. But market making is the one strategy where fees aren't a footnote, they're the main event: you're capturing a few basis points of spread on massive turnover, so the trading-fee line is often bigger than your edge before you optimise it. That's exactly why a rebate is worth more to a Hummingbot operator than to almost any other trader. Here's how the fees land, and how to bind an up-to-40% rebate on the account your bot runs.

The short version

Hummingbot has no fees of its own. It's free open-source software; your account pays the exchange's schedule — ~0.10% spot, ~0.02% maker / 0.05% taker on USDT perps at the regular tier.
Market making is nearly all maker volume. A pure-market-making config rests bids and asks in the book, so most fills are makers — the cheapest fee, and on some tiers a maker rebate.
Fees dominate a market maker's P&L, so returning up to 40% of them via an account-bound rebate lifts net margin more, in percentage terms, than for almost anyone else.

Three reductions stack: maker routing (already native to market making), a good maker/VIP rate, and the account rebate. None of them touch your strategy logic.

Why fees are the market maker's biggest enemy

A directional trader chasing a 5% move barely notices a 0.02% fee. A market maker is the opposite animal: you quote a tight two-sided spread, get filled thousands of times, and pocket a sliver each round-trip. Turn over $20M of notional to net a fraction of a percent, and the fee on that $20M is your largest single expense — frequently larger than the gross spread you captured before costs. This is the asymmetry that defines the strategy: the thinner your margin and the higher your churn, the more a fee cut is worth. A rebate that returns up to 40% of fees isn't a nice-to-have for a market maker; it can be the difference between a strategy that clears and one that bleeds.

Where fees land in a Hummingbot strategy

Hummingbot places your quotes as orders on the exchange; the fee on each fill is set by the venue's schedule and by whether the order rested as a maker or crossed as a taker. A few config parameters govern that:

bid_spread / ask_spread — how far from the mid your quotes sit. Wider spreads rest more reliably as makers (cheaper fee, lower fill rate); tighter spreads fill more but risk being taken or crossing.
order_refresh_time — how often quotes are cancelled and re-posted. Frequent refreshing keeps you at the top of the book but generates more order activity to manage.
order_amount and order levels — size per quote and how many price levels you ladder; these set your turnover, and turnover is what the fee (and the rebate) scale with.
Connector / market type — spot vs perpetual picks the fee schedule. Perps use lower maker rates but add funding on inventory you hold.

The maker-vs-taker question is the same one every bot faces — the mechanics are covered in maker vs taker fees explained. For a market maker, the goal is simply to maximise the share of fills that rest as makers, because that's both your cheapest fee and where any maker-rebate tier kicks in.

The three reductions, stacked

Lever	Where you set it	What it does	Touches strategy?
Maker routing	Native to market making (spreads/refresh)	Most fills rest as makers (~0.02% perp) instead of taker (~0.05%)	No — it's the strategy
Maker / VIP tier	Exchange account (volume + maker ratio)	Lowers the maker fee, sometimes to a maker rebate at higher tiers	No
Referral rebate	Account referral binding	Returns up to 40% of net fees, weekly in USDT	No

Reference rates are regular-tier and illustrative; real numbers depend on venue, product, VIP/maker tier and your maker ratio. The point isn't the exact basis points — it's that these are three independent reductions a market maker can run at once.

Worked example — a Hummingbot market maker at $20M/month

A pure-market-making config quotes both sides on a couple of liquid perps, turning over $20,000,000 notional per month, with roughly 90% of fills resting as makers:

Blended fee, no rebate: (0.90 × 0.02%) + (0.10 × 0.05%) = 0.023% → $20M × 0.023% = $4,600/month in fees (~$55,200/year).
With up-to-40% rebate: rebate ≈ $4,600 × 40% = $1,840 back → net ≈ $2,760/month (~$33,120/year).
The saving: about $1,840/month, ~$22,000/year, on identical volume and an unchanged strategy.

For a strategy netting a thin spread on that turnover, $22,000/year of recovered fees can be a large fraction of the whole year's profit. That's the market-maker asymmetry in numbers: the rebate is a rounding error to a swing trader and a make-or-break line to you.

How to bind the rebate (the step outside the bot)

This is the lever most Hummingbot users leave on the table, because it happens outside the software. The rebate binds to your exchange account, not to the API key or the bot — so the sequence is:

Register your Binance or OKX account under a rebate via the Binance rebate or OKX rebate page, before you generate the API key.
Create a trade-only API key (withdrawals disabled; IP allowlist if your VPS has a fixed IP).
Add the key to Hummingbot's exchange connector and run your strategy as normal.

The full account-vs-key explanation — including what to do when a bot already runs on an existing account — is in how to claim a fee rebate when you connect a bot via API key. The one rule to remember: register first, connect second, and never let a third party register the exchange account for you if you want to keep the rebate. A legitimate rebate never needs your password or withdrawal rights — see are crypto fee rebates safe.

Don't forget funding

A rebate cuts your trading fees. If your Hummingbot strategy runs on perpetuals and accumulates inventory, you also pay or receive funding on whatever you hold — and a rebate can't touch that, because funding is a transfer between traders, not an exchange fee. A perp market maker should manage inventory and budget funding as a separate line; the distinction is laid out in funding rate vs trading fee.

FAQ

Does Hummingbot charge fees?+

Hummingbot is free, open-source software you self-host, so it has no fees of its own. Every cost you pay goes to the exchange your API key trades on. Historically some strategies could opt into a small maker-rebate share tied to the project's own token mechanics, but the core bot is free to run. On Binance and OKX your account pays roughly 0.10% spot and 0.02% maker / 0.05% taker on USDT perps at the regular tier, before any discount or rebate. What Hummingbot controls, through its strategy and spreads, is whether your orders rest in the book as makers — and for a market-making bot that is nearly all of them.

Why is a fee rebate worth more to a market maker?+

Because a market maker earns a tiny spread on enormous turnover, the trading fee is the single largest cost line in the strategy — often larger than the edge itself before optimisation. A directional trader who doubles their money cares little about a 0.02% fee; a market maker capturing a few basis points per round-trip lives or dies on it. Returning up to 40% of that fee therefore lifts net margin far more, in percentage terms, than it would for almost any other trader. The same rebate rate is simply worth more when fees are your dominant cost.

How do I get a rebate on a Hummingbot bot?+

The rebate is bound to your exchange account, not to Hummingbot or its API key. Register your Binance or OKX account under a rebate first, generate a trade-only API key (withdrawals disabled), and paste it into Hummingbot's exchange connector. Every fill the bot posts on that account then earns an up-to-40% rebate, settled weekly in USDT, with no change to your strategy files. Rotating the API key for security never affects the binding, because the rebate follows the account.

Do maker rebates and a referral rebate stack on Hummingbot?+

They are separate mechanisms. An exchange maker-rebate or negative-maker-fee program (usually VIP or market-maker tiers) lowers or reverses the fee at the moment of the trade based on your volume and maker ratio. A referral rebate returns a share of the net commission your account generates, settled later by the channel. Because they act at different stages, a maker-routed Hummingbot strategy that also qualifies for a good maker rate and is bound to a rebate compounds the reductions. Model your own numbers — the interaction depends on tier and product — but they are not mutually exclusive.

Does a rebate cover funding on a Hummingbot perp market-making strategy?+

No. A rebate only returns a share of trading fees. On perpetual futures you also pay or receive funding on any inventory you are left holding, and a rebate cannot touch that — funding is a transfer between long and short traders, not an exchange fee. A perp market maker that accumulates directional inventory should manage and budget funding separately from the fee optimisation. The rule is the same as for any bot: cut the trading-fee line with maker routing plus a rebate, and treat funding as its own line item.

Run the same Hummingbot strategy on a lower cost base

Market making is where a rebate pays off most. Bind an up-to-40% rebate on your Binance or OKX account, keep quoting as maker, and settle weekly in USDT. No strategy change, no code change, no extra permissions.
