Who This Is For
This guide is for crypto futures traders who want to close or reduce existing positions without accidentally opening new ones, especially when using leverage.
What You’ll Need
- A funded account on a crypto exchange that supports futures trading (like Binance, Bybit, or Deribit)
- Basic understanding of long and short positions
- Familiarity with limit and market orders
- Access to the exchange’s advanced order form (usually in the futures trading interface)
Key Takeaways
- A reduce-only order ensures you only close or reduce an existing position — it won’t open a new one in the opposite direction.
- It’s a risk management tool that prevents accidental overexposure when you’re already leveraged.
- Most major futures exchanges support reduce-only orders, but the exact label might vary (e.g., “Close Only” or “Reduce Only”).
Step 1: Open the Futures Trading Interface
First, log into your exchange and head to the futures trading page. You’ll see an order entry panel. Look for the dropdown or checkbox that says “Reduce Only,” “Close Position,” or something similar. On Binance, it’s a checkbox labeled “Reduce-Only” right next to the order type selector. On Bybit, it’s under the “Order” section as “Reduce Only” toggle.
Make sure you’re on the right trading pair and contract (like BTCUSDT perpetual). If you don’t see the option, check your account settings — some exchanges require you to enable advanced order types first.
Step 2: Select Your Order Type and Direction
Now, choose whether you’re reducing a long or a short position. Here’s the key: the reduce-only order must be in the opposite direction of your open position. So if you’re long (you bought), you need to place a sell order. If you’re short (you sold), you need a buy order.
Set your order type — limit, market, or stop-limit. Most traders use a limit order to get a better price, but a market order works if you want to exit fast. Just remember: with reduce-only, the exchange will automatically reject the order if it would increase your position size instead of decreasing it. That’s the whole point.
For example, say you have 1 BTC long. Placing a reduce-only sell order for 0.5 BTC will close half your position. But if you accidentally try to sell 2 BTC, the exchange will block it — because that would exceed your current long size and effectively open a short position.
Step 3: Check Your Position Size and Leverage
Before you confirm, double-check your current position size. This step is critical because reduce-only orders work based on your net position, not your total bought volume. If you have 10 ETH long and you place a reduce-only sell order for 12 ETH, the exchange will only fill 10 ETH (closing your position) and cancel the remaining 2 ETH. It won’t turn into a short.
Also watch out for leverage. A reduce-only order doesn’t change your leverage — it just reduces the position. So if you’re 10x leveraged, closing half your position means you still have the same leverage on the remaining half. Some traders prefer to adjust leverage manually, but that’s a separate step.
Here’s a quick table to visualize it:
| Your Position | Reduce-Only Order | Result |
|---|---|---|
| Long 5 BTC | Sell 3 BTC (Reduce-Only) | Position becomes Long 2 BTC |
| Short 10 ETH | Buy 10 ETH (Reduce-Only) | Position is fully closed (0 ETH) |
| Long 1 BTC | Sell 2 BTC (Reduce-Only) | Order rejected or partially filled |
Step 4: Confirm and Monitor the Order
Hit the “Buy/Long” or “Sell/Short” button depending on your direction. The exchange will show a confirmation with a “Reduce-Only” tag. Check that tag — if it’s missing, don’t confirm. Go back and toggle it on.
Once submitted, your order will appear in the open orders tab with a “Reduce Only” label. It’ll stay there until filled or canceled. You can set a take-profit or stop-loss on the same position without using reduce-only — those are separate features. But for manual exits, reduce-only is your safety net.
After the order fills, your position size updates instantly. You can verify in the “Positions” tab. If something looks off, cancel any remaining orders and check your trade history.
Common Pitfalls and Risks
⚠️ Risk: Forgetting to toggle reduce-only when you’re trying to exit a losing trade. You might accidentally open a new position in the opposite direction, doubling your exposure. Mitigation: Always double-check the reduce-only checkbox before hitting confirm. Some exchanges let you set it as default — turn that on.
⚠️ Risk: Using reduce-only with stop-loss orders incorrectly. If you set a reduce-only stop-loss order below market price for a long position, it works fine. But if the price gaps down, the stop might trigger at a worse price than expected. Mitigation: Use limit stop-loss orders when possible to control slippage.
⚠️ Risk: Partial fills on reduce-only orders. If you’re reducing a large position with a limit order, only part of it might fill before the price moves away. The unfilled part stays open. Mitigation: Use market orders for full exits during high volatility, or break your order into smaller chunks.
