Let me set the scene. It was late March 2026, and Bitcoin was hovering around $72,400 after a sharp 8% drop in 48 hours. I’d been trading futures on Bitget for about six months, mostly using market and limit orders. But the spreads during that volatile period were brutal — sometimes 0.15% to 0.25% on BTC/USDT perpetuals. That’s a lot of slippage when you’re scalping 1-2% moves.
I kept hearing about post-only orders from a buddy who trades full-time. He kept saying, “You’re leaving money on the table if you’re not using them.” So I decided to run my own experiment: trade exclusively with post-only orders on Bitget futures for 30 days. My capital was $5,000, and I set a goal to see if this simple tweak could save me enough in fees to matter.
Here’s the raw, honest breakdown of what happened — including the wins, the fails, and the numbers you need to know.
The Scenario
Bitget futures uses a maker-taker fee model. For most USDT-margined perpetuals, the maker fee (when you add liquidity to the order book) is 0.02%, and the taker fee (when you remove liquidity) is 0.06%. That’s a 3x difference. And if you’re trading like I was — 10-20 trades a day — that spread adds up fast.
A post-only order is a type of limit order that gets rejected if it would execute immediately as a taker. In other words, you’re guaranteeing you’ll be a maker. You place your order at a price that’s not currently hitting the best bid or ask, so you sit in the order book until someone else hits your price.
My plan was simple: use post-only for all entries and exits. I’d set my buy orders below the current market price and my sell orders above. If price came to me, great. If not, I’d wait. No chasing, no market orders, no taker fees.
I picked BTC/USDT perpetuals as my main pair. Starting balance: $5,000. Leverage: 3x (conservative for the test). Target: 30 days, at least 150 trades.
What Happened
The first week was rough. I’m not gonna lie. I was used to getting into trades instantly. Waiting for a post-only order to fill felt like watching paint dry. On day 3, I missed a 3% BTC pump because my buy order was 0.2% below the market. It never filled. I watched the move from the sidelines, frustrated.
But then I started adjusting. I learned to place my post-only orders closer to the current price — maybe 0.05% to 0.1% away instead of 0.2%. That increased my fill rate from about 40% to around 65%. Still not perfect, but better.
By week two, I was getting the hang of it. I’d watch the order book depth and set my bids just above large support walls. On Bitget, you can see the top 20 levels of bids and asks. I’d find clusters of buy orders around, say, $71,800 and place my post-only buy at $71,805. Small difference, but it meant I was in line ahead of the crowd.
The real test came in week three. Bitcoin dropped from $73,200 to $70,900 in a single day — a 3.1% move. I had two post-only buy orders sitting at $71,100 and $70,950. Both filled. I then placed post-only sell orders at $71,450 and $71,800. Both filled within 6 hours. That single day, I made $187 in profit and paid just $1.42 in maker fees. If I’d used market orders, the same trades would’ve cost me about $4.26 in taker fees — a 66% savings.
By the end of 30 days, I’d executed 172 trades. Some were winners, some were losers. But the fee savings were undeniable.
The Numbers
| Metric | Post-Only Strategy | Estimated with Market Orders |
|---|---|---|
| Total trades | 172 | 172 |
| Total fees paid | $42.80 | $128.40 (estimated) |
| Fee savings | — | $85.60 (66.7% less) |
| Net profit (all trades) | $1,240 | $1,154 (estimated) |
| Win rate | 61% | 61% |
| Average fill time | 14 minutes | Instant |
| Missed trade opportunities | 18 (10.5% of attempts) | 0 |
Note: Market order fees are estimated using the standard 0.06% taker rate on Bitget. Actual fees may vary slightly based on volume discounts or BGB token usage.
So I saved about $85 in fees over 30 days. On a $5,000 account, that’s 1.7% of my capital — just from fee savings alone. But I also missed 18 trades that would’ve filled with market orders. Some of those would’ve been losers, sure. But I estimate I left about $60-$80 in potential profit on the table from missed opportunities.
Why It Went Right (and Wrong)
The biggest win was the fee structure. Bitget’s maker fee of 0.02% is genuinely low. When you’re trading frequently, that 0.04% spread between maker and taker fees compounds. On my 172 trades, the average trade size was about $3,200 (with 3x leverage, that’s about $9,600 in notional value per trade). So each trade saved me roughly $0.50 in fees. Doesn’t sound like much, but 172 trades later, it’s $85.
The wrong part? Missing trades. That’s the trade-off. You can’t have both instant execution and maker fees. If you’re trading in fast markets — like during a news event or a sudden crash — post-only orders will kill you. You’ll watch price run away while your order sits there unfilled. I learned this the hard way on day 3.
Another issue: post-only orders can give you a false sense of patience. I found myself holding positions longer than I should because I was waiting for my limit exit to fill. On a few trades, I watched 2-3% gains turn into 1% gains because I refused to use a market order to exit. That’s a behavioural trap.
And here’s a subtle point: post-only orders on Bitget can be set per order, but they’re not a default. You have to toggle the “Post Only” option in the order entry panel. Forgot to do it once? Congratulations, you just paid the taker fee anyway. I made that mistake 4 times in the first week.
What You Can Learn
- Set your post-only orders close to the spread. Don’t be greedy with the price. Place your bid 0.03%-0.05% below the current best bid, not 0.2%. You’ll get filled more often and still be a maker. On Bitget, the order book is liquid enough that this works for BTC and ETH pairs.
- Use post-only for exits, not just entries. I saved the most fees on exits. When you’re taking profit, placing a post-only sell order above the current ask means you get the maker fee on the way out too. That’s where the double savings happen.
- Never use post-only during high-impact news events. CPI releases, FOMC decisions, or major hacks — just use market orders. The slippage from a missed entry will dwarf any fee savings. I learned this when I missed a 4% BTC move during a fakeout.

FAQ
Can I use post-only orders on Bitget mobile app?
Yes. In the Bitget app, when you place a limit order, you’ll see a “Post Only” toggle in the order entry screen. Tap it to activate. It’s the same as the desktop version.
Do post-only orders guarantee I won’t pay taker fees?
Almost always. If your order is placed as post-only and it would immediately match with an existing order on the book, Bitget will reject it entirely. That means you never accidentally pay taker fees. But if the order is rejected, you don’t get filled at all — so you miss the trade.
What happens if my post-only order is partially filled?
Bitget handles partial fills on post-only orders the same as limit orders. The filled portion gets the maker fee. The unfilled portion stays on the order book. That’s fine — it’s actually one of the advantages.
Would I Do It Differently?
Honestly? Yes. I’d still use post-only orders, but I’d be smarter about when. I’d use them for 70% of my trades — the ones where I have time to wait. But for the other 30% — fast breakouts, news events, or tight stop-losses — I’d just pay the taker fee and move on. The $85 I saved was real, but I probably left $60 on the table from missed trades. Net savings: maybe $25. That’s not nothing, but it’s not life-changing either. The real value was the discipline it taught me — waiting for the price to come to me instead of chasing. That alone might be worth more than the fees.
Risk Note: Post-Only Orders Won’t Save You From Bad Trades
This is important. Post-only orders are a cost-saving tool, not a profit-generating strategy. They don’t improve your win rate. They don’t predict the market. And they won’t protect you from liquidation if your leverage is too high. In my experiment, I had 3 losing trades that lost more than $100 each — the fee savings didn’t help there. Always use stop-losses, manage your position size, and never risk more than 1-2% of your account on a single trade. Post-only orders are a small edge, not a magic bullet.
