If you’ve ever placed a market order on a crypto futures exchange and watched the fee eat into your small profit, you’ve felt the sting of being a taker. But there’s a smarter way to trade on Bitget Futures if you’re patient and value cost efficiency: the Post-Only order. This isn’t some hidden setting for pros only. It’s a simple tool that lets you add liquidity to the order book instead of removing it, and Bitget rewards you for that with lower fees. Let’s break down what a Post-Only order is, exactly how to use it on Bitget Futures, and why it might save you serious money over time.
Why Compare These Order Types?
Before we dive into the “how,” we need to understand the “why.” On Bitget Futures, every order you place is either a market order, a limit order, or a trigger order. But within limit orders, there’s a special subtype: Post-Only. The core comparison here is between a standard limit order and a Post-Only limit order. Both let you set a specific price, but they behave differently when the market hits your price. A standard limit order can sometimes execute immediately, turning you into a taker and costing you the higher taker fee. A Post-Only order guarantees that your order only adds liquidity. If it would execute immediately as a taker, it gets canceled instead. This isn’t just a technical quirk — it’s a fee-saving strategy that active traders rely on.

| Execution Guarantee | No — may fill partially or fully at limit price | No — order canceled if it would fill immediately |
| Best For | Getting filled quickly at a desired price | Saving on fees, adding liquidity |
| Risk of Instant Fill | Yes — you pay taker fee | No — order canceled to avoid taker fee |
| Typical Fee Savings | 0% (taker fee applies on instant fill) | Up to 50% vs. taker fees on Bitget |
Post-Only Order Deep Dive
A Post-Only order is a limit order with one critical rule: it can only be placed on the order book as liquidity, never executed as a market taker. On Bitget Futures, when you check the “Post-Only” box while placing a limit order, the exchange checks your order against the current order book. If your buy price is at or above the best ask, or your sell price is at or below the best bid, the order would cross the spread and execute immediately. Instead of letting that happen, Bitget cancels the order entirely. You get a “Post-Only order would be taker” error message. That’s the system protecting you from paying taker fees.
How do you actually set this up? Log into Bitget Futures, go to the trading interface for any perpetual contract. Choose “Limit” as your order type. Then, below the price and quantity fields, you’ll see a small toggle labeled “Post-Only.” Click it so it turns blue. Now enter your limit price and quantity. Place the order. If your price doesn’t cross the spread, it sits on the order book as a maker order. If it does cross, you get an error and the order is rejected. That’s it. It’s that simple. But there’s a nuance: if the market moves away from your price, your order might never fill. That’s the trade-off for lower fees.
When would you use this? Any time you’re placing a limit order that you don’t need filled instantly. For example, if you want to buy Bitcoin at $30,000 and the current best ask is $30,050, your limit order won’t cross the spread — it will sit on the book. You’d use Post-Only here to save the 0.02% maker fee instead of the 0.04% taker fee. Over 100 trades, that 0.02% difference adds up. On a $10,000 position, you save $2 per trade. On 100 trades, that’s $200. Not life-changing, but it compounds.
Key Takeaways:
- ✅ Strengths: Guarantees lower maker fees on every fill. Protects you from accidentally becoming a taker. Ideal for swing traders and scalpers who add liquidity. Reduces overall trading costs by 30-50% compared to using takers.
- ⚠️ Limitations: Order will be canceled if it would fill immediately. Can result in missed entries during fast-moving markets. Requires patience and a price that stays on the book. Not suitable for stop-losses or urgent entries.
Standard Limit Order Deep Dive
A standard limit order on Bitget Futures is the default. You set a price and a quantity, and the order sits on the book until it’s filled or canceled. But here’s the catch: if your limit price crosses the spread — meaning your buy is at or above the best ask, or your sell is at or below the best bid — the order executes immediately as a taker. You get filled at your price, but you pay the higher taker fee. This is what catches many new traders off guard. They see “limit order” and assume they’re always a maker. Not true.
Standard limit orders are best when you want immediate execution at a specific price. Say the market is at $30,000, and you place a limit buy at $30,010. If the best ask is $30,005, your order crosses the spread and fills instantly. You get your position, but you pay the taker fee. That might be fine if speed matters more than cost. For example, if you’re chasing a breakout and need to get in now, the taker fee is a small price to pay for entry. But if you’re patient and can wait for your price to come to you, a Post-Only order is better.
How do you place a standard limit order? On Bitget Futures, select “Limit” from the order type dropdown. Don’t check the Post-Only box. Enter your price and quantity. Hit “Buy/Long” or “Sell/Short.” The order goes to the book. If it fills immediately, you’re a taker. If it sits, you’re a maker. The exchange decides your fee status based on whether your order added or removed liquidity at the moment of fill. So a standard limit order gives you flexibility — you might get maker fees if you’re lucky, but you might also get taker fees if the market moves against your intended price.
Key Takeaways:
- ✅ Strengths: Can fill immediately at your desired price. lower-risk of order rejection due to spread crossing. More likely to get filled in fast markets. Works for both patient and urgent entries.
- ⚠️ Limitations: You might pay taker fees if the order crosses the spread. No fee savings compared to Post-Only. Can lead to higher overall trading costs for frequent traders. Less control over fee tier.
Head-to-Head: When to Use Each
Let’s look at three real scenarios to see which order type wins.
Scenario 1: Patient Swing Trader — You’ve identified support at $29,500 for Bitcoin. You want to buy there and hold for a few days. The current price is $30,000. Your limit order at $29,500 won’t cross the spread. Use Post-Only. You’ll pay maker fees when it fills, saving about 0.02% per trade. Over a month, that’s meaningful.
Scenario 2: Breakout Chaser — Ethereum breaks above $2,000 with volume. You want to buy now before it runs. The best ask is $2,010. You place a limit buy at $2,015. It crosses the spread and fills instantly. Use a standard limit order (or even a market order) because speed matters. Post-Only would cancel your order, and you’d miss the move.
Scenario 3: Scalper Adding Liquidity — You scalp on 1-minute charts. You place buy orders at the bid and sell orders at the ask, hoping to catch small spreads. These orders sit on the book and get filled when the market touches them. Use Post-Only for both sides. You collect maker fees on every fill. This is a classic market-making strategy, and Bitget’s fee structure rewards it. Just be careful — if the market gaps through your price, you might not get filled.
Which Should You Choose?
This isn’t financial advice — it’s educational guidance. The choice comes down to your trading style and goals. If you’re a long-term swing trader or a scalper who places orders away from the current price, Post-Only is almost always better. You save on fees and add liquidity to the market. If you’re a momentum trader or need to enter positions quickly during volatile moves, a standard limit order (or market order) is more practical. The fee difference is small per trade but large over volume.
Here’s a simple rule: if you can wait for your price and your order won’t cross the spread, use Post-Only. If you need speed or your price is aggressive, don’t. You can also use both — place a Post-Only order at your ideal price and a standard limit order at a more aggressive price for urgency. That’s called a “split order” strategy.

Risks and Considerations
No trading strategy is without risk, and Post-Only orders have their own pitfalls. The biggest is missed opportunities. In fast-moving markets, your Post-Only order might sit on the book while the price runs away from you. You could miss a breakout or breakdown entirely. That’s the cost of fee savings. If you’re trading a volatile altcoin with thin liquidity, your Post-Only order might never fill at all. The spread can be wide, and your price might not be hit.
Another risk is psychological. You might become too focused on saving fees and miss good trades. A 0.02% fee difference is irrelevant if you miss a 10% move. Always prioritize trade quality over fee savings. Also, be aware that Bitget’s fee structure can change. As of July 2026, maker fees on Bitget Futures are 0.02% and taker fees are 0.04%. But these can be adjusted based on your VIP level or trading volume. Check the current fee schedule on Bitget’s website before relying on these numbers.
Finally, there’s the risk of order cancellation due to price slippage. If you place a Post-Only buy at $30,000 and the best ask is $30,001, your order sits. But if the ask drops to $30,000, your order would cross the spread and get canceled. You lose your spot in the queue. This can be frustrating if the price bounces quickly. Use limit orders with a small buffer — say $29,990 instead of $30,000 — to avoid this issue. Always test with small amounts first.
