Free practice for the Flow Traders math test
A Flow Traders-style practice configuration: 75 multiple-choice questions in 8 minutes, with −2 for every wrong answer. Public formats vary by region, role, and recruiting cycle. It is free with no signup, and the set is the same on every visit.
75 questions · 8 minutes · multiple choice
+1 per correct answer, −2 per wrong answer, skips are free. Integer, decimal and fraction arithmetic in a 4-choice format. TradeMind practice target: 70 net on this 75Q / 8-minute configuration (not a firm cutoff). Format and scoring may vary by region, role and recruiting cycle.
What this test is
Flow Traders, the Amsterdam-headquartered ETF market maker, uses timed arithmetic in parts of its trading recruitment. Public formats differ across locations and cycles. This simulator uses a demanding 75-question, 8-minute configuration to train speed, accuracy, and skip discipline. It does not claim that every candidate gets this exact paper.

The expected value of guessing
The −2 penalty changes the strategy. A blind guess on a 4-choice question has an expected value of 0.25 × (+1) + 0.75 × (−2) = −1.25. Eliminating one option brings it to −1, and with two options left it is still −0.5. Answering beats skipping only when you are more than two-thirds sure. Answer quickly when you are sure, and skip when you are not.
How the distractors are built
The wrong options are the answers produced by common slips: an off-by-one in the tens digit, a missed carry, numerators added straight across a fraction sum, a misplaced decimal point. Every careless path leads to one of the choices. This simulator builds its distractors the same way.
How to prepare
- Accuracy first. Drill untimed until integer and decimal arithmetic is almost error-free. With a −2 penalty, speed without accuracy has negative expected value.
- Then fractions. Most candidates lose time here, on common-denominator sums and near-miss numerator distractors. Instant recognition of equivalent fractions (2/4 = 1/2) avoids most of the traps.
- Then full 8-minute runs. Pacing, skip discipline, and fatigue in the last 90 seconds only show up in a full-length run. One or two runs a day, reviewing every miss, does more than long untimed sessions.

Questions
What is the Flow Traders math test?
The exact test varies by region, role, and recruiting cycle. Current public sources describe 60 questions in 6 minutes on one hosted route, 80 in 8 for Hong Kong and New York, and 75 questions in 10 minutes on some Flow Traders careers pages. This page uses a demanding 75-question, 8-minute practice configuration for skill training. It does not claim to be the one live format.
Why is the 70-point practice target so high?
On this TradeMind configuration, 70 out of 75 with a −2 wrong-answer penalty requires arithmetic that stays nearly automatic under time pressure. Two careless errors cost four net points. It is a training target, not a universal or officially published Flow Traders cutoff.
Should I guess or skip on the Flow test?
Skip. With −2 per wrong answer, a blind guess on a 4-choice question has expected value 0.25×(+1) + 0.75×(−2) = −1.25 points. Even with two options left, a guess is worth −0.5, so answer only when you are more than 2/3 sure. Guessing is one of the most common ways candidates lose points.
How does the format differ from Optiver's 80 in 8?
Both are ~8-minute arithmetic tests. Optiver's classic format uses typed answers with a −1 penalty; Flow's is multiple choice with a reported −2 penalty. TradeMind's practice target for it (70 of 75) is also higher than the ~60 of 80 cited for Optiver. Multiple choice sounds easier, but the distractors come from common miscalculations, and the larger penalty punishes 'close enough' answers.
Is this the real Flow Traders test?
No. It is an independent practice reconstruction based on public descriptions of the format. It trains the same skills and timing, but the questions are not Flow Traders' own, and the live format may change. TradeMind is not affiliated with Flow Traders.
