Futures order errors and warnings: what each message means
What it is
When you press Buy/Long or Sell/Short, the app checks the order first. If something is wrong it shows a red notification and does not send the order. If the order is sent but the exchange rejects it or cannot fill it, you see Order failed. This article lists every message and what to do.
Where the numbers in a message come from: the app replaces {...} with the real value (for example the minimum quantity for the contract). Those limits are set by the platform per contract, so check the numbers shown in your own message.
Notification titles
| Title | Meaning |
|---|---|
| Order validation failed | The app found a problem before sending. The description lists each problem on its own line. Nothing was sent. |
| Order failed | The order was sent, or the app tried to send it, and it did not go through. The description explains why. |
| Order submitted | Success. |
| Close position order submitted | Success for a reduce-only close order. |
Quantity (size) messages
| Message | Cause | What to do |
|---|---|---|
| "Quantity is required" | Size is empty. | Enter a size or use the slider. |
| "Quantity must be greater than 0" | Size is zero or not a number. | Enter a positive size. |
| "Min quantity: {value}" | Size is below the contract minimum. | Increase the size to the value shown. |
| "Max quantity: {value}" | Size is above the contract maximum. | Reduce the size or split the order. |
| "Quantity will be adjusted to {value}" (warning) | Your size does not match the contract's size step. | The app rounds down to the value shown. |
| "Minimum Qty is {minQty} {asset}" | Shown under the size box when below the minimum. | Enter at least that size. |
Price messages
| Message | Cause | What to do |
|---|---|---|
| "Price must be greater than 0" | Limit or Stop Limit price is empty or zero. | Enter a price. |
| "Price must be at least {value}" | Price is below the contract's lowest allowed price. | Raise the price. |
| "Price must not exceed {value}" | Price is above the contract's highest allowed price. | Lower the price. |
| "Price will be rounded to {value}" (warning) | Your price does not match the contract's price step. | The app rounds it; check the value. |
| "Stop price must be greater than 0" | Stop Price is empty or zero. | Enter the Stop Price. |
| "One or more prices are outside the supported range" | After rounding, a price falls outside what the contract accepts. | Move the price closer to the market. |
| "Mark price is unavailable for this conditional order" | The app could not read the mark price. | Wait a moment and try again. |
Order value and margin messages
| Message | Cause | What to do |
|---|---|---|
| "Minimum order value is {minNotional} USDT" | The order's value (size times price) is below the contract minimum. | Increase the size or price so the value reaches the minimum. |
| "This order requires {required} USDT margin, but only {available} USDT is available. Reduce the size or add funds." | Not enough available margin. The Buy/Long or Sell/Short button is greyed out with a red alert. | Reduce the size, or use Deposit / the transfer icon to add funds. |
| "Order uses most of available balance" (warning) | The order needs more than 95% of your available margin. | You can still send it, but price moves may leave little room. Consider a smaller size. |
| "Position value exceeds max {max} USDT for {leverage}x leverage" | The position would be larger than the contract allows at your leverage. | Lower the size, or lower your leverage in the leverage window (higher leverage allows a smaller maximum position). |
| "Leverage {leverage}x exceeds max {max}x for this position size" | At this position size the contract allows only a lower leverage. | Reduce the size, or lower your leverage to the maximum shown. |
Available margin (Avbl) is shown above the summary. Open orders and open positions use margin, so your available amount can be lower than your wallet balance.
Reduce Only and TP/SL messages
| Message | Cause |
|---|---|
| "No open position to reduce for this symbol" | Reduce Only is ticked but you have no position on this contract. |
| "Cannot submit reduce-only while both long and short positions are open" | Both directions are open on this symbol. |
| "Invalid reduce-only quantity" | Size missing or invalid for a reduce-only order. |
| "Reduce-only quantity exceeds current position size (max {maxQty})" | Size larger than your position. |
| "TP/SL is unavailable when Reduce-Only is enabled" | Both options are on. |
| "Enter take profit or stop loss" | TP/SL ticked with no prices. |
| "Take profit must be greater than 0" / "Stop loss must be greater than 0" | Invalid price. |
| "Take profit must be above reference price" / "Take profit must be below reference price" | Take profit on the wrong side of the mark price for your direction. |
| "Stop loss must be below reference price" / "Stop loss must be above reference price" | Stop loss on the wrong side of the mark price for your direction. |
See the Reduce Only and TP/SL article for the rules.
Market order and slippage messages
| Message | Cause |
|---|---|
| "Slippage must be a number" | Slippage box has text that is not a number. |
| "Minimum slippage is 0.1%" | Value below 0.1. |
| "Maximum slippage is 5%" | Value above 5. |
Order failed messages
| Message | Cause | What to do |
|---|---|---|
| "No liquidity matched this {tif} order, so nothing was executed. Try a limit order or a smaller size." | An IOC or FOK order found nothing to fill. Nothing was placed. | Use a limit order (GTC), change the price, or reduce the size. |
| Text from the exchange (for example a plain sentence describing the problem) | The exchange refused the order. The app shows the exchange's own text, and a request ID when one is available. | Follow the text. If unclear, contact Support with the text and request ID. |
| Voucher messages such as "Your voucher has expired." | The voucher rules were not met. | See the Vouchers articles. |
Data and trading availability messages
| Message | Cause |
|---|---|
| "Orderbook data may be outdated. Trading is temporarily disabled." | Live prices stopped updating. Refresh the page or check your connection. |
| "Balance data may be outdated. Trading is temporarily disabled." | Balance data stopped updating. |
| "Trading starts in {time}" / "Starting soon..." | Contract not open yet. |
| "Couldn't load market data. Check your connection and try again." | Market data failed to load. Use Try again. |
Leverage and margin mode messages
See the dedicated articles: "Failed to change leverage", "Failed to change margin mode", "Margin mode cannot be changed while you have an open order or position." and "Leverage and margin mode are locked while a voucher position is open."
Checklist when an order will not go through
- Read the exact message and match it above.
- Check Avbl against the margin the order needs (Cost).
- Check size and price against the minimums, steps and ranges.
- If you are using Reduce Only or TP/SL, check the rules.
- Refresh the page and try once more. Do not send the same order repeatedly.
FAQ
I pressed the button and nothing happened. Look for a red notification at the screen edge or an alert above the buttons. If the buttons are grey, margin or live data is the cause.
Why does the maximum position shrink when I raise leverage? Each contract has position size limits per leverage level. See the leverage article.
When to contact Support
Include: the exact message text (copy it or take a screenshot), the request ID if shown, symbol, side, order type, price, size, leverage and margin mode, your Avbl at the time, and the date and time with time zone.
Safety reminder
Never share your password, 2FA code, seed phrase or private key with anyone, including people claiming to be Support.
