Flips & ROI: profit after the market tax

A flip is buying a card low and selling it higher. Simple in theory, but the in-game market takes a 10% cut on every sale, so half the “obvious” flips lose money. This guide explains how DiamondOps ranks flips by real, after-tax profit — and how to read every column.

Why the spread isn’t the profit

The headline spread — buy-now minus sell-order — looks like free money, but the game taxes every sale 10%. Buy a card for 9,000 and sell it for 10,000 and you don’t make 1,000; you make 10,000 minus the 1,000 tax minus your 9,000 cost — just a few hundred stubs, and sometimes nothing at all. The flips page does this subtraction on every candidate, so the Profit column is what actually lands in your stub balance.

The columns that matter

Profit — net stubs after the 10% tax. This is the number to trust.
ROI — profit as a percentage of your buy cost. ROI is how you compare a cheap flip against an expensive one fairly: a 300-stub profit on a 3,000 card (10%) beats a 500-stub profit on a 50,000 card (1%) if you want your stubs working hard.
Confidence — a Prime / Solid / Watch / Thin tag summarizing how reliable the flip looks given margin, volume, and risk. Prime is a wide, liquid, low-risk gap; Thin means the profit is real but small or fragile.
QS Floor — the card’s quick-sell value, the guaranteed price the game pays. When quick-sell beats the market sell-order, you have a “QS Viable” flip with a built-in floor under your downside.
Profit / min — estimated stubs per minute of flipping, based on typical fill time for the card’s price range. Great for deciding where to spend a limited grinding session.

Filtering to the flips you’ll actually make

The filter bar lets you shape the table to your strategy:

Confidence tabs — jump straight to Prime when you want only the safest gaps.
QS Viable — show only flips with a quick-sell floor, for risk-averse grinding.
Cap Friendly — Prime/Solid confidence, fast turnover, and clean bot risk in one toggle: the set-and-forget flips.
Position & quirk — narrow to a slot you’re building or a quirk you care about.

A repeatable flipping loop

Sort by ROI (or Profit/min if you’re short on time) and skim the Prime rows first.
Check the bot-risk badge — a manipulated rally can evaporate before your sell order fills. See anomalies & bot-risk.
Open the card detail to confirm the spread is stable on the price chart, not a one-hour blip.
Buy at the sell-order, list at the buy-now, and let the QS floor protect you if the market moves against you.
