Martingale Strategy Order Failure Reasons

Published on Jun 16, 2025Updated on Jun 27, 20254 min read

Insufficient Balance

If you end a cycle early while the strategy is running at a loss, the Martingale-strategy account may not have enough balance to place the next cycle’s order. In that case, the system will automatically retry the order with a quantity equal to
min(available balance in your Martingale account, originally planned order size).

  • If the retried quantity is below the minimum order size for the trading pair, the retry fails. The strategy continues to run normally (except when an initial order fails).

  • If the retried quantity ≥ the minimum order size, the retry succeeds and the strategy keeps running as usual.

For minimum order sizes, refer to the

Perpetuals - Trading Rules
and
Spot - Trading Rules
.

For example, if you created a futures Martingale strategy with a maximum investment amount of 100 USDT and incurred a 50 USDT loss in the first cycle, then chose to end the cycle early, the next cycle’s opening order may fail due to insufficient balance. Suppose the available balance in your Martingale strategy account is 5 USDT at that time, the system will retry the opening order with min( 5 USDT , originally planned order size )

  • If this min( 5 USDT , originally planned order size ) is below the pair’s minimum order size, the retry fails but the strategy keeps running (initial-order failures excepted).

  • If the min( 5 USDT , originally planned order size ) ≥ the minimum order size, the retry succeeds and the strategy continues uninterrupted.

Price Limit Violation

Due to market fluctuations, order book depth, or other objective factors, the order may trigger the

price limit
control during volatile market conditions. In this case, the system will retry the order using the latest price limit to ensure the strategy continues.
Example: If the highest buy price for BTC is 100,000 USDT and your buy order is placed at 101,000 USDT, the order will fail. The system will then retry the order using the price limit of 100,000 USDT, and the strategy will continue running.

Order Size Below Minimum amount requirement

If the order size is below the minimum required quantity, the order will fail. For minimum order sizes, refer to the

Perpetuals - Trading Rules
and
Spot - Trading Rules
. If the initial order is below the minimum size, the system will stop the strategy. If an safety order is below the minimum, the system will ignore the order, and the strategy will continue running.

The most common reason an order size falls below the platform’s minimum is that you end a losing cycle early, leaving insufficient balance for the next cycle. When the system retries the order, if your available balance is below the minimum order amount, it will return an error—“Order size below minimum”—and the order will fail. For details, please refer to the earlier explanation in this article about insufficient balance.

Another scenario is a sharp price rally: a fixed-amount order that once met the minimum can become too small in coin terms. For example, if BTC jumps from 20 000 USDT to 60 000 USDT while your strategy still places 2 USDT buy orders, the amount that used to purchase 0.0001 BTC now buys only 0.000033 BTC, which is below the 0.0001 BTC minimum. The order will therefore be rejected.

Order Canceled by Risk Control

When you apply overly high leverage in a perpetual-contract Martingale strategy, and facing significant losses, the chance of triggering the platform’s risk-control cancellations increases, causing any open orders to be revoked.

  • Unfilled safety orders: If risk controls cancel an unfilled safety order, the system will not retry the order for your account’s safety; it will simply skip that order and the strategy will keep running.

  • Unfilled take-profit or stop-loss orders: If these orders are canceled by risk controls, the system will retry them to ensure you can close the position smoothly, and the strategy continues operating.

  • Unfilled initial order: If the initial opening order is canceled by risk controls, the system will stop the strategy entirely.

Exceeding Position Tier Limit

In a perpetual Martingale strategy, if your open order causes the total position size to exceed the tier limit, the order will fail. If the initial order exceed the tier limit, the system will stop the strategy. If an safety order exceed the tier limit, the system will ignore the order, and the strategy will continue running.
