Dumping vs waiting it out
Your buy filled and the price went the other way. Now you have two options and no good ones: take the hit and free the slot, or leave the sell offer up and hope. Both cost gold. The point of this lesson is to make you price both before you pick.
There is no buy limit on selling. You can always leave a position on the Grand Exchange, at some price, immediately. That makes dumping feel like a safety valve, and it is, but it is a valve with a meter on it, and most flippers never read the meter.
What an instant exit actually costs
Dumping means pricing your sell offer at or below the highest resting bid so it trades against buyers who are already there. Three things come out of your pocket at once.
- The spread. You bought near the ask and you are selling into the bid, so you concede the whole gap you were trying to earn, in the wrong direction.
- The move. Whatever the price has fallen since you bought comes out on top of that.
- The tax. 2% of the sale price, rounded down per item, capped at 5,000,000 gp per item, and nothing under 50 gp. The tax is charged on a losing sale exactly as it is on a winning one.
That third item is the one people forget when they say "I will just take the small loss". A dump on a 40 million gp item hands the tax alone 800,000 gp before you count the price move.
The three costs of waiting
Waiting is not free either, and being able to name its three parts is what turns this from a feeling into a calculation.
Opportunity cost
Gold sitting inside an unsold position is gold not doing a flip. If your usual rotation reliably turns your bank at some rate per four hour window, then every window you spend holding is that rate multiplied by the size of the position. This is nearly always the largest cost of waiting and it is invisible, which is why it gets ignored.
Slot cost
Members get eight Grand Exchange slots and free players get three. A stubborn sell offer occupies one of them indefinitely. If you run seven active items, holding one dead position costs you one eighth of your entire trading capacity for as long as it sits.
Drift risk
The price can keep going. Waiting is only free if the market comes back, and the market owes you nothing. On items driven by an update or a supply change, the direction usually has a reason behind it and the reason does not care that you are holding.
A decision rule with numbers
Here is the rule, and it deliberately asks about causes before it asks about prices.
Dump when the reason you bought has gone. Wait when only the price has moved. If an update, a supply change or a piece of news has invalidated the thesis, the position is wrong at any price and holding just adds time to the loss. If nothing changed except that you were early, waiting is a normal cost of doing business.
Once you have passed that test, the arithmetic decides how long waiting is worth. Compute two numbers.
- The dump gap. What you would receive after tax by selling into the bid now, against what you would receive after tax at your target price. The difference is what waiting is trying to save.
- The carry. Your position size multiplied by whatever your gold reliably earns per four hour window in your normal rotation. That is what waiting costs per window.
Divide the first by the second and you get the number of windows waiting can be worth. If that number is smaller than your honest estimate of how long the recovery takes, dump. If it is larger, wait, and set a review point rather than checking every ten minutes.
A position that went wrong
Twenty Abyssal whips bought at 798,000. Position size 15.96M. The plan was to sell at 830,000.
The price slipped. The highest bid is now 766,000.
Dump now: tax = floor(0.02 × 766,000) = 15,320. You receive 750,680 each, 15.01M total. Realised loss 946,400 gp.
Sell at your cost, 798,000: tax = 15,960. You receive 782,040 each, 15.64M total. Loss 319,200 gp, which is the tax and nothing else.
Waiting is trying to save 627,200 gp.
If your bank reliably earns even 0.5% per four hour window, 15.96M carries at about 80,000 gp per window. 627,200 divided by 80,000 is roughly 8 windows, a little over a day.
So the answer here is precise rather than emotional: waiting pays if you believe the bid gets back to 798,000 inside about a day, and does not pay if you think it takes a week. Whip volume is around seven thousand trades a day, which is healthy enough that a day is a reasonable horizon under normal conditions. If instead a patch had just made whips less relevant, the thesis is gone, the recovery estimate is unbounded, and you dump.
Notice the other lesson buried in that example. Selling at exactly your buy price is still a loss, because the tax is charged anyway. Break even on the Grand Exchange is always above your entry, and on a 798,000 gp item it is about 16,000 gp above.
Laddering out
The choice is not binary. A slot holds one offer, but a position can be split across attempts in time.
A common approach on a position that has gone against you is to sell a third into the bid immediately, which frees capital and stops the position from growing in your head, then place the remainder at a price you would be content with and give it a fixed window. You take a known small loss on part of it in exchange for removing the pressure to make one perfect decision about all of it.
On items with thin buy sides this is close to mandatory anyway. Dumping the whole lot at once walks straight down the bid ladder and each successive unit fills lower, so the average you achieve is worse than the bid you measured. Splitting the exit across a few hours usually gets a better average, simply because new buyers arrive.
When waiting is denial
Patience and denial look identical from the outside. These are the tells.
- You have moved your target down more than once. A target that follows the price is not a target, it is a running commentary.
- You bought more to improve the average. Adding to a position because it is losing is a different trade from the one you researched, and it is usually a worse one.
- You cannot say what would change your mind. If no price and no news would make you sell, you are not holding a position, you are holding an item.
- You stopped counting the slot. If the position has been parked so long you no longer think of that slot as usable, the cost has already been paid and you did not notice.
- The reason has changed since you bought. Buying for a spread and holding for a recovery are two different strategies. Switching between them mid position is how a small loss becomes a large one.
When dumping is the mistake
The opposite failure is real too, and it is more expensive than people think because it happens in a rush.
Dumping into an obviously temporary imbalance is the classic. If an item has been sold hard for twenty minutes with no news attached, the bid you are hitting may be someone else's opportunistic low offer rather than the market's real level. Dumping during the quietest hours of the day is a related error, since the buy side is thinnest exactly then, which is the subject of the next lesson.
Dumping a full limit into a thin item at once is the third. On a low volume item there may be only a handful of resting bids, and clearing them all takes you far below the price you read. Check the item's daily volume before you decide that an instant exit is even available at the price you are imagining.
The checklist
- Has the reason I bought changed? If yes, exit and stop calculating.
- What do I actually receive after tax if I dump right now?
- What do I receive after tax at my target, and what is the gap between the two?
- What does this position cost me per window in carry and in slots?
- How many windows of waiting does the gap buy, and is my recovery estimate shorter than that?
- Can I split the exit instead of choosing all or nothing?
- What price or event would make me change this decision, and have I written it down?
Answer those seven and you will make the wrong call sometimes, which is unavoidable. You will not make it by accident, which is the part you control.
Making the decision reach you
The seventh question is the one people answer honestly and then never act on, because writing a price down does nothing if you are not looking at the screen when it arrives. Set a price alert instead. Every tracked flip can carry one, set from the row or from the Alerts page, and it fires exactly once when the price gets there, so a level wobbling around your number will not spam you. Pick the figure while you still have a view rather than while you are watching a position go against you, and the decision comes to you instead of you going hunting for a reason to change it. Nothing is armed for you by default; this is a choice you make per flip.
The carry cost in the arithmetic above is easier to see when the position is written down. Track the flip and it sits in My Flips with its running profit and loss, so a slot you stopped counting is visible as a slot rather than as a thing you have quietly stopped thinking about. Sorting positions into named portfolios helps here too, because a portfolio carries its own deployed capital figure, and a strategy that is mostly stuck says so in a number rather than in a feeling.
Before you decide an instant exit is even available, check the other side is there. The Last sell and Trades/h columns on the Margins board are the direct measure of the thin-item problem described above: if the sell side last traded half an hour ago, the bid you are planning to hit is a quote rather than a queue, and dumping into it will land well below the number you read.
