Order execution terms

Breakeven stop

A breakeven stop is a stop loss moved to the entry price once a trade is sufficiently profitable, removing the risk of the position turning into a loss.

The appeal is obvious and psychological: once the stop is at entry, the worst realistic outcome is a scratch. Many traders describe this as making the trade "free", which is not quite true — the spread and commission are still paid, so a stop at exact entry is a small loss, not zero.

The statistical case is weaker than the emotional one. Moving to breakeven tightens the stop at precisely the moment the trade is working, which converts a share of eventual winners into scratches. Whether that is worth it depends entirely on how often price retraces to entry before continuing, and on gold that retracement is common.

If you use one, trigger it on structure rather than on a fixed percentage of the target. A stop moved to breakeven because price cleared the swing point that was containing it has a reason; a stop moved because the trade reached 50% of target has only arithmetic behind it, and arithmetic does not know where the market is likely to pull back to.

Limit order

Also called: Buy limit, Sell limit.

A limit order is an instruction to trade only at a specified price or better, which guarantees your price but not that the order will ever be filled.

A buy limit sits below the current market and a sell limit sits above it. The order rests in the book until price reaches your level, and if price never gets there the order simply expires or is cancelled. That is the trade-off: you control the entry price completely, and in exchange you accept that some trades will never happen.

Limit orders are the natural fit for mean-reversion and level-based approaches, where the whole premise is that price has moved too far and will come back. They fit poorly with momentum and breakout approaches, where waiting for a better price usually means waiting for the move to be over.

There is a practical constraint on gold specifically. Most brokers enforce a minimum distance between the current price and any pending order — the stop level — and on XAUUSD that distance is often wide enough to make tight limit entries impossible. Systems that were designed on a symbol with a zero stop level frequently fail on gold for exactly this reason.

Market order

A market order is an instruction to buy or sell immediately at the best price currently available, rather than at a price you specify in advance.

A market order trades certainty of execution for uncertainty of price. You are telling the broker to fill you now, whatever the current book looks like, which means the order will almost always be executed but not necessarily at the number you saw on screen when you clicked.

The gap between the price you expected and the price you received is slippage, and it is a function of how fast the market is moving and how deep the book is at that moment. On a quiet afternoon the difference is usually invisible. During a news release it can be substantial.

Automated systems on gold almost always use market orders rather than limit orders, and the reason is structural: the setups worth trading on XAUUSD are usually confirmed by a move that has already started, so an order waiting patiently at a better price is an order that watches the trade leave without it. Our own engine places market entries with `sl=0, tp=0` and attaches protection immediately afterwards, because the broker requires it — see why that matters.

Requote

A requote is a broker response offering a different price than the one requested, asking the trader to accept or reject it before the order is executed.

Requotes belong to dealing-desk execution, where the broker is the counterparty and quotes prices rather than routing to a market. If price has moved since you clicked, the desk declines your price and offers a new one. On true ECN routing there is nothing to requote — you either get filled at whatever is in the book, or you get slippage.

For a human trader a requote is an annoyance. For an automated system it is a failure mode, because the EA has to decide in milliseconds whether the new price still satisfies the setup, and most do not handle it gracefully. Systems built for one execution model often behave unpredictably on the other.

MetaTrader exposes a deviation setting that governs how much price movement you will silently accept before the order is rejected. Set it too tight and orders fail during exactly the volatile conditions your strategy was designed for; set it too loose and you accept fills far from your intended price. On XAUUSD the working range is wider than most traders assume — see order fails to execute.

Slippage

Slippage is the difference between the price a trade was expected to execute at and the price it actually executed at, and it can be positive or negative.

Slippage happens because the price shown on your screen is the last price, not a promise. Between the moment your order leaves your terminal and the moment it reaches the broker, the book can change. In fast conditions it changes a lot.

It is not always against you. Positive slippage — a fill better than requested — is real and common on genuine ECN execution. A broker whose slippage is consistently negative and never positive is telling you something about how orders are handled, and that pattern is worth checking in your own trade history rather than taking on trust.

For automated systems slippage is the main reason live results underperform a backtest. A replay fills every order at the modelled price; reality does not. When we compared our own replay against live trades, execution differences and same-strategy stacking together accounted for most of the gap — which is why any backtest figure on this site is published alongside its caveats rather than as a headline.

A stop can also fill far from its level when gold gaps over a weekend: we measured 52 of those gaps.

Stop loss

Also called: SL, Stop loss meaning, What is stop loss, Whats a stop loss.

A stop loss is a resting order that closes a position once price moves a set distance against it, defining the maximum expected loss before the trade is opened.

The stop loss is the single most important number in a trading system, because it is the one that turns an opinion into a measurable risk. Without it, position size means nothing — you cannot know what a trade risks until you know where you are wrong. Every position-sizing formula in existence takes stop distance as an input.

Stop placement should follow market structure rather than an arbitrary dollar amount. A stop placed just beyond the swing point that would invalidate the setup is doing its job; a stop placed at "$5 because that is what I want to lose" is a wish attached to an order ticket, and it will be hit by ordinary noise.

On XAUUSD this matters more than on most instruments. We measured a median daily range of $76 across a year of five-minute bars, and at that volatility a $2 stop is hit by ordinary noise within an hour of entry 81% of the time. A $10 stop is hit 34% of the time. Neither is really a stop. Use ATR to size stops against current conditions instead.

Whether a gold stop should be a fixed distance or scaled to volatility is measured in our stop-loss study.

Stop order

Also called: Buy stop, Sell stop.

A stop order is a pending instruction that becomes a market order once price trades through a specified level, used to enter on breakouts or to exit losing positions.

A buy stop sits above the current market and a sell stop sits below it — the mirror image of a limit order. The logic is different too: instead of betting price will return, you are betting that once price passes a level it will keep going. This is why breakout systems are built on stop orders.

Once triggered, a stop becomes a market order, which means it inherits every property of one, including slippage. A stop order is therefore not a guaranteed price. On a fast gold move the trigger and the fill can be several dollars apart, and that difference is not a broker error — it is what a stop order is.

The same mechanism is what makes a stop loss imperfect protection. Traders often assume the stop caps the loss exactly. In practice it caps the loss at roughly that level under normal conditions, and only approximately during a gap or a news spike. Any position size calculated on the assumption of an exact stop is slightly optimistic — see the lot size calculator.

Take profit

Also called: TP.

A take profit is a resting order that closes a position once it reaches a specified level of gain, locking in the result without requiring the trader to be watching.

A take profit defines the reward half of the risk-reward ratio. Most systematic approaches place it as a multiple of the stop distance rather than at a round price, because that keeps the arithmetic of the system consistent regardless of how volatile the market happens to be that day.

The choice of multiple has a direct and mechanical effect on win rate. A target at twice the stop distance will be reached less often than a target at one times the stop, so a 2:1 system is expected to win less frequently than a 1:1 system and still make more money. Traders who judge a system by win rate alone consistently misread this.

Our engine fixes the target at 2.0 times the stop distance across every market regime. That is a deliberate simplification: earlier versions scaled the ratio per regime, and testing across 2026 and an out-of-sample 2025 period showed the scaling was fitting noise rather than capturing anything real. The strategy list records which ideas survived that kind of check and which did not.

Trailing stop

Also called: Trailing stop loss.

A trailing stop is a stop loss that moves in the direction of profit as price advances, locking in gains while leaving the position open to run further.

The mechanism is simple: as price moves in your favour by some amount, the stop is moved up by the same amount, and it never moves back. A trailing stop therefore converts an open profit into a floor under the trade, at the cost of guaranteeing that you exit below the peak.

That cost is the part traders underestimate. A trailing stop cannot both protect a gain and let a trade breathe — every dollar of protection is a dollar of room removed. On a volatile instrument the trail is frequently hit by a normal retracement in a move that then continues without you.

We ship with trailing switched off, and that is an evidence-based decision rather than an oversight. Trailing was enabled in earlier versions with breakeven at 50% of target and a profit lock at 80%; measured against a fixed 2:1 target over the same periods, it reduced net result on XAUUSD. The setting still exists for anyone who wants it — see the setup guide — but the default reflects what the testing showed.
