ETH Limit Orders: What to Check After a Partial Fill
An ETH spot limit order can fill only part of its requested quantity when suitable opposing orders are insufficient. The executed portion becomes a trade; the remaining portion can stay open under the selected order rules. A limit price controls acceptable execution prices, not a promise that the entire order will fill.
Separate requested, filled and remaining quantities
Imagine a buy order for 2 ETH at a limit of 2,000 USDT per ETH. If 0.6 ETH fills, the remaining requested amount is 2 - 0.6 = 1.4 ETH. The original 2 ETH is not the amount already bought.
All numbers here are hypothetical. Verify the actual pair, balances, size rules and available controls on the ETH spot page; availability can depend on account and region.
Check the fills rather than one chart price
Suppose 0.4 ETH executes at 1,999 USDT and 0.2 ETH at 2,000 USDT. The executed notional is 0.4 × 1,999 + 0.2 × 2,000 = 1,199.6 USDT. The quantity-weighted average is 1,199.6 / 0.6, approximately 1,999.33 USDT per ETH before fees.
Several fills can have different prices and fee treatment. Use transaction history to determine the actual assets received and charges. A buy limit can execute at its limit or better, subject to the order rules.
Understand why the remainder can wait
Other orders may be ahead at the same price, and available sellers can change. A chart touching the limit does not prove enough matching quantity reached your order. Read order-book depth to distinguish displayed prices from executable quantity.
The example describes a conventional resting limit order. Time-in-force choices can change whether any unfilled quantity remains; use only options actually offered on the order screen.
Confirm cancellation before replacing
A cancellation request concerns the unfilled remainder. It does not reverse completed fills. More quantity may execute before the cancellation is confirmed, so read the final order status and updated filled quantity before submitting a replacement.
If the final filled amount is 0.8 ETH, a replacement intended to reach the original 2 ETH would be based on 1.2 ETH, not the earlier 1.4 ETH. Replacing from a stale quantity can exceed the intended exposure.
Reconcile the final balance and costs
Check executed quantity, average price, fees, any remaining open order and available balance. Depending on the fee currency, net ETH received can differ from gross executed quantity. Avoid counting reserved funds as freely available.

Common questions
Does a partial fill mean the entire order failed?
No. The executed portion remains a completed trade.
Does canceling undo the ETH already purchased?
No. It only requests cancellation of the still-open remainder.
Should a replacement always use the original quantity?
No. Reconcile the latest fills and the intended total first.
