How Do You Close a Partial Position in MT4?
A partial close in MetaTrader 4 reduces the volume of an open position without closing it entirely. The trader specifies a smaller lot size than the position’s total volume, and the broker closes the requested portion while leaving the remainder open. Partial closes are commonly used to lock in some profit on a position that has moved favourably while keeping exposure to further upside, or to reduce risk by trimming the position as it approaches a key level. The procedure is straightforward but has a few rules and quirks worth understanding. This article walks through the steps, the volume constraints, the behaviour of the remaining position, and the common pitfalls.
Why Partial Close
Three common reasons drive partial closes. The first is profit-taking. A trader holding a 1.0 lot position that has moved in their favour may close half (0.5 lot) at a first target level, locking in profit on that portion, and let the remaining 0.5 lot run toward a further target. The second is risk reduction. As a trade moves against the trader, closing part of the position reduces exposure without exiting entirely, useful when the trader still believes in the setup but wants to protect equity. The third is adapting position sizing to changing conditions. If volatility spikes, a smaller position may be more appropriate, and partial closing achieves this without exiting completely.
Step-by-Step Procedure
The partial close procedure uses the same Order window that is used to close a position entirely.
The first step is to open the close dialog. In the Terminal window, with the Trade tab visible, right-click on the position to be partially closed and select “Close Order.” A double-click on the position’s row achieves the same result.
The Order window opens with the position’s details displayed. The Volume field, which by default shows the full lot size of the position, can be edited to a smaller value. For a 1.0 lot position, entering 0.5 closes half the position. Entering 0.1 closes one-tenth.
After the volume is set, a yellow Close button appears at the bottom of the dialog. The button displays the symbol and the volume to be closed, in the format “Close #[ticket] [volume] [symbol] [direction] at [price].” Clicking the button submits the partial close request to the broker.
If the broker accepts the request, the position’s volume in the Trade tab is reduced by the closed amount, and a separate closed trade appears in the History tab for the portion that was closed. The remaining open position retains the original ticket number but with the reduced volume.
Volume Constraints
Partial closes are subject to two constraints. The first is the broker’s minimum lot increment. Most brokers allow lots in increments of 0.01 (one micro lot), but some impose a 0.10 minimum increment, and a few exotic instruments may have larger minimums. The partial close volume must respect this minimum.
The second constraint is that the partial close volume cannot exceed the total volume of the position. Attempting to close 1.5 lots from a 1.0 lot position would either be rejected by the platform or interpreted as a full close, depending on the platform version.
A practical consequence of the first constraint is that closing exactly half of a position is sometimes not possible if the result would be below the minimum increment. For example, half of a 0.01 lot position (the minimum) is 0.005 lots, which is below the smallest tradable size. The position would need to be closed entirely or held in full.
Behaviour of the Remaining Position
After a partial close, the remaining open position keeps the original ticket number and the original entry price. The stop loss and take profit attached to the position remain unchanged and now apply to the smaller volume. The floating profit or loss is recalculated based on the smaller remaining lot size.
For traders who have set a stop loss based on a dollar amount rather than a price level, the dollar value of the stop changes when the volume changes. A stop placed at 50 pips below entry on a 1.0 lot EUR/USD position represents $500 of risk. After closing half the position, the same 50-pip stop now represents only $250 of risk. The price level of the stop has not changed; only the dollar value has, because the position is smaller.
Subsequent partial closes can be applied to the remaining position. A 1.0 lot position can be reduced to 0.5, then to 0.25, then to 0.10, and so on, as long as each partial close respects the broker’s minimum increment.
Common Pitfalls
Three pitfalls come up regularly with partial closes.
The first is confusing partial close volume with remaining volume. The volume entered in the close dialog is the amount being closed, not the amount remaining. Entering 0.3 on a 1.0 lot position closes 0.3 lots and leaves 0.7 lots open, not the reverse.
The second is partial closing without adjusting the stop loss. If the original stop loss was sized for the full position, holding the remaining portion with the same stop in dollar terms may not be intended. Some traders adjust the stop after partial close to bring the remaining trade to a more conservative position, such as moving it to break-even.
The third is broker variation. Some brokers’ execution policies generate a new ticket for the remaining position rather than keeping the original ticket number. This is rare but can cause confusion in trade journals and EAs that track positions by ticket number.
Partial Closes Versus Other Approaches
Partial closes are one of several techniques for managing open positions. Alternatives include using trailing stops to dynamically protect profit, scaling out through multiple take profit levels (where parts of the position have different take profits set), and reversing the direction entirely with an opposite trade.
| Technique | What It Does | Best For |
|---|---|---|
| Partial close | Reduces volume manually | Discretionary profit-taking |
| Trailing stop | Moves stop loss with price | Letting profits run with automatic protection |
| Scaling out via TPs | Closes portions at preset prices | Defined exit plan |
| Hedging with opposite trade | Reverses some or all exposure | Brief tactical adjustments |
Each approach has its place. Partial close is the most flexible because the trader decides in the moment exactly how much to close, but it requires active management. Trailing stops and scaling out via TPs are more automatic.
Frequently Asked Questions
How do I open the partial close dialog? Right-click on the position in the Terminal’s Trade tab and select “Close Order,” or double-click the position’s row. The Order window opens with the position’s details, and the Volume field can be edited to specify how much of the position to close.
What volume do I enter to close half a position? Enter half the position’s current volume. For a 1.0 lot position, enter 0.5 in the Volume field. The yellow Close button at the bottom of the dialog will then submit the request to close 0.5 lots, leaving 0.5 lots open.
Can I partially close any position? Generally yes, as long as the resulting partial close volume is at least the broker’s minimum increment (commonly 0.01 lots). Positions at the minimum lot size cannot be partially closed because any smaller volume would be below the minimum.
What happens to the stop loss after a partial close? The stop loss remains at the same price level it was set to. Only the position’s volume changes. The dollar value of the stop is proportionally smaller because it now applies to a smaller position, but the price at which the stop triggers does not move.
Does the remaining position keep the same ticket number? In most cases yes. The remaining open position retains the original ticket number with the reduced volume. A small number of brokers’ execution policies may generate a new ticket, but this is uncommon.
Why is the Close button greyed out? The button may be greyed out if the requested volume is below the broker’s minimum increment, if the volume entered is larger than the position’s total volume, or if the market is currently in a state where the broker cannot process the close request (off quotes, weekend hours, or similar).
Can I partial close pending orders? No. Pending orders cannot be partially closed because they have not yet executed. A pending order can only be modified (changing its trigger price or stops) or deleted. After a pending order fills and becomes an open position, it can be partially closed like any other position.
