Why Did My Crypto Futures Order Fail?
The most common reason is that your USDT Margin Account doesn't have enough available margin to cover the order's initial margin plus fees. When this happens, the app offers to edit the amount or add margin. Add USDT to your USDT Margin Account, reduce the order size, or cancel pending orders holding margin. Other causes are covered below.
| Symptom / Condition | Possible Cause | Solution |
|---|---|---|
| The order fails and the app offers to edit the amount or add margin. | Your available margin is less than the order's initial margin plus fees. | Add USDT to your USDT Margin Account, or reduce the order size. Lowering your leverage won't help here, because lower leverage needs more margin for the same order size. |
| The order is rejected because of its quantity. | The quantity is below the contract's minimum size, or it isn't a whole multiple of that minimum. | Check the contract's minimum size in the app, then enter a quantity that is at least that amount and goes up in whole steps of it. |
| You can't set the leverage you want. | The leverage is above the contract's maximum. Most contracts go up to 25x, while BAT, FIL and ZRX are capped at 10x. | Choose a whole-number leverage from 1x up to the contract's maximum. Open orders on the contract can also block a leverage change, so cancel them first if needed. |
| You have USDT in your USDT Margin Account, but the order still fails for lack of margin. | Part of your balance is already held by open positions or pending orders, so it isn't available for a new order. | Cancel pending orders you no longer need to release their margin, or add more USDT. |
| Only orders that close or reduce a position go through. | Your margin ratio is above 75%, which is a Final Margin Call. At this level, only orders that close or reduce your exposure are accepted. | Add margin or reduce your positions to bring the margin ratio down before opening new positions. |
| You can't place any Crypto Futures order at all. | You haven't passed the Knowledge Test yet. It is required before your first Crypto Futures trade unless you traded Crypto Futures on Pluang before 25 September 2026. | Complete the Knowledge Test in the app. Once you reach the passing grade, you can place orders. |

If none of these explains the failure, contact Pluang Care via live chat in the app or email tanya@pluang.com with the contract name, the order details and the approximate time you placed it.
Related questions:
Q: Why doesn't lowering my leverage fix a margin error?
Lower leverage needs more initial margin for the same order size, not less. To need less margin, reduce the order size, or raise the leverage within the contract's maximum. Keep in mind that higher leverage also raises your liquidation risk.
Q: Are fees included in the margin my order needs?
Yes. Your available margin must cover the order's initial margin plus its trading fees. Check the fee breakdown shown before you confirm the order.
Q: Can I open new positions during a Final Margin Call?
No. While your margin ratio is above 75%, only orders that close or reduce your exposure are accepted. Add margin or reduce your positions first.
Q: Do my pending TP/SL orders use up margin?
No. No margin is reserved for TP/SL orders, so they never cause an order to fail for lack of margin. Other pending orders can hold margin, though.
Q: Do I need to pass the Knowledge Test before trading?
Yes, unless you traded Crypto Futures on Pluang before 25 September 2026. It is a mandatory step before your first Crypto Futures trade, and you can't place orders until you pass.
