Eclipse Trading Online Assessment: Mixed Options and Probability Test
Eclipse Trading, the options market maker in Hong Kong, Sydney, Shanghai and Chicago, screens graduates with a battery of short online tests. Independent candidate reports describe several separate 10 to 15 minute tests on mental math, financial knowledge, options and probability, plus a long mental-math sprint; one prep site describes a combined mixed test of 14 multiple-choice questions in 30 minutes on trading knowledge and probability. The mixed test is rebuilt below as a timed replica with a free sample, and our Eclipse interview guide covers the rest of the battery.
Eclipse mixed test: 14 questions in 30 minutes
One prep site reports a mixed Eclipse test of 14 multiple-choice questions in 30 minutes combining trading and options knowledge with probability. Candidates also describe a battery of separate 10 to 15 minute tests (mental math, financial knowledge, options, probability) plus a long mental-math sprint. This replica covers the single-source mixed format.
- One source reports 14 multiple-choice questions in 30 minutes, about 2 minutes each
- Roughly half options and trading knowledge (parity, Greeks, straddles, hedging, futures carry), half probability and expected value, plus market-making edge
- No calculator; free navigation, so you can skip and return before submitting
- Other candidates report separate short tests (mental math, financial knowledge, options, probability) and a longer mental-math sprint instead
The free sample draws a fresh mix from its own question pool on every retake, separate from the full run, which draws from a larger pool of its own. The review explains every answer.
- Do the quick options items first (time value, parity, breakevens) and bank the time for probability questions.
- For straddle estimates, use 0.8 x S x vol x sqrt(T) and pick the closest option; do not try to run Black-Scholes by hand.
- On arbitrage questions, compute both sides of the identity first (C - P against S - PV(K), or futures against fair value), then pick the trade that sells the rich side.
- Use symmetry and linearity on probability items: gaps between drawn cards, complements and corner triangles in the unit square save minutes.
The rest of the battery
Mental arithmetic is the part most candidates report losing time on. The free drills below cover the sprint, and the Eclipse interview questions page covers the options theory rounds that follow the tests.

Sources and how current this is
The 14-question, 30-minute mixed test has a single prep-site source; independent candidate reports from Hong Kong (2023) and Sydney (2024) describe separate 10 to 15 minute tests on mental math, financial knowledge, options and probability, and a long one-question-per-page mental-math sprint. Treat counts and timings as candidate-reported. Every practice question here is original and generated, and every answer is checked by code.
Eclipse Trading OA: FAQ
What is on the Eclipse Trading online assessment?
Candidates describe a battery of short timed tests: mental math, financial and options knowledge, and probability, each roughly 10 to 15 minutes, plus a long mental-math sprint. One prep site describes a combined 14-question, 30-minute mixed test of options knowledge and probability, which the replica here follows.
What options knowledge does Eclipse test?
Reported topics are put-call parity, intrinsic and time value, the signs of the Greeks, straddle breakevens and simple hedging, all at the level of a first options course rather than stochastic calculus.
Is the Eclipse practice test free?
The replica has a free timed sample with no signup that ends in a scored review. The full simulation, which draws a fresh mix of questions on every run, is part of QuantVault Pro.
