A trailing stop moves with price in your favour and never moves back. Enter your entry, the current gold price and how far behind you want the stop to sit, and this tool returns the exact stop level, the profit it has already locked in, and how much room price still has before the position closes itself.
A trailing stop has two moving parts: an anchor and a distance. The anchor is the best price the position has reached since entry — the high-water mark for a long, the low-water mark for a short. The distance is how far behind that anchor you are willing to sit. The stop is simply the anchor minus the distance for a long, or the anchor plus the distance for a short.
That max is the whole idea in one symbol. If price has moved in your favour, the anchor rises and the stop rises with it. If price has moved against you, the anchor stays where it was, so the stop does not slide backwards and hand back ground it had already defended. A trailing stop is therefore a ratchet, not a rubber band.
The tool treats the current price as the best price reached, which is the natural assumption for a live position. To model a stop set at an earlier peak, enter that peak as the current price instead.
You buy gold at $4,120 with a stop $18 below, so the initial stop is $4,102 and the initial risk is $18 per ounce — $1,800 on one standard lot of 100 ounces. Price rallies to $4,168. The anchor is now $4,168, the stop ratchets up to $4,150, and the trade is locked at $30 per ounce, or $3,000. Open profit is $48 per ounce, $4,800, so $1,800 of it — 37.5% — is still exposed. If the stop is hit from here the position closes at $4,150 and the $3,000 stays banked.
| Stage | Price | Stop | Locked per oz | Locked on 1 lot |
|---|---|---|---|---|
| Entry | $4,120.00 | $4,102.00 | −$18.00 | −$1,800.00 |
| +$20 | $4,140.00 | $4,122.00 | $2.00 | $200.00 |
| +$48 | $4,168.00 | $4,150.00 | $30.00 | $3,000.00 |

Notice the break-even point: the stop reaches your entry once price is $18 above it. From that moment the trade can no longer lose, provided the stop is honoured — which is exactly why traders trail rather than set and forget.
The distance is the only real decision in the whole calculation, and it should come from how gold actually moves rather than from how much you would like to keep. Gold routinely travels $15 to $30 in a quiet session and considerably more around US data releases, so a trail tighter than the noise will be clipped by ordinary fluctuation before the trend pays you.
Whatever you pick, keep it wide enough that the trade can breathe and tight enough that the locked profit is worth having. If a stop-out would wipe out the gain, the position is too large — a sizing problem rather than a stop problem, which the position size calculator handles.
The most common mistake is trailing too soon. Move the stop to break-even after $5 of profit and a trend trade becomes a coin flip, because gold retraces $5 constantly on its way to $80. Wait until the trade has earned the width of its own stop before the first adjustment, then ratchet in steps.
The second mistake is trailing on the wrong timeframe. A stop based on five-minute candles will be hit by the noise that a four-hour chart does not even register. Set the distance from the timeframe that produced the signal, then let it run.
The third is trusting the level to fill exactly. A trailing stop becomes a market order once triggered, so a gap through it — a weekend gap, a flash move on a headline — can fill well beyond the level. On gold, where weekend gaps of $10 to $30 are ordinary, that slippage deserves to be part of the plan, and it is the same reason leverage and liquidation need to be understood before position size is chosen.
Finally, the level is only as good as the venue honouring it. Knowing whether your order is triggered off the bid, the ask or a midpoint is worth more than another decimal place in the calculation. The gold trading academy covers execution mechanics.
No — that is its defining feature. For a long, the stop only rises; for a short, it only falls. If price reverses, the anchor stays at the best level reached and the stop stays with it, so profit already protected cannot be handed back by a looser setting.
Wide enough to survive normal noise. A practical starting point is 1.5 to 2.5 times the average true range of your trading timeframe, or roughly 0.4% to 0.8% of the gold price. Anything tighter than the session's typical range tends to be triggered by ordinary fluctuation rather than a real trend change.
No. Once triggered it becomes a market order, so gaps and fast moves can fill beyond the stop. Gold gaps over weekends and reacts violently to data releases, so treat the calculated level as a target rather than a promise, and size the position for the slippage you might actually get.
