All 24 skills in this domain, alphabetically. Hover a row for its situation; open it for the full playbook.

A

adverse-selection-measurement-for-passive-ordersUse when passive fills keep happening just before the market moves against you, measuring forward markouts in basis points against the prevailing mid at each horizon. Aggressive orders pay the spread instead and are measured elsewhere.trading

C

clock-drift-monitoring-alerting-thresholdsUse when a host stamping reportable events must prove its clock stays inside the MiFID II RTS 25 divergence limit for that activity, evaluating PTP offset and daemon state and latching a halt on breach. Disciplining the clock is a separate skill.rts-25 clock-synchronization-ptp-for-trading-hostsUse when standing up or auditing the time-sync stack itself on a Linux trading host: NIC hardware timestamping, ptp4l against the grandmaster profile and phc2sys to the system clock, with linuxptp telemetry parsed as reported.ieee-1588 co-location-provider-selection-and-network-topologyUse when deciding where to place a latency-sensitive server across co-location facilities and cross-venue links, decomposing one-way and round-trip budgets from propagation physics and published equipment specifications.latency-budget colocation-latency-budget-accountingUse when profiling the in-host hot path of a co-located server, decomposing NIC ingress to NIC egress into nanosecond phases and auditing each trace against its stage budget. Everything outside the box is a different skill.tick-to-trade

E

exchange-fee-tier-and-rebate-structure-analysisUse when computing the signed net cost of a fill mix at one venue under its maker-taker or inverted schedule and deciding whether the next volume tier is worth chasing. Allocating flow across venues is execution-venue-fee-tier-optimization.maker-taker exchange-gateway-redundancy-and-failover-testingUse when redundant order-entry sessions to a venue must fail over safely, confirming liveness first, fencing the failing session against split-brain and resolving the standby's own sequence numbers.fix-failover exchange-matching-engine-behavior-under-loadUse when estimating how much extra delay a matching engine adds as inbound message rates approach its capacity, and converting that utilisation into a quoting directive. A closed-form model, not telemetry.queuing-delay exchange-self-match-prevention-configurationUse when several order-generating processes under one beneficial owner quote the same instrument on the same venue, configuring native self-match prevention such as the CME iLink and FIX identifier and instruction fields.stp

F

fpga-based-market-data-processing-evaluationUse when deciding between continuing to optimise a kernel-bypass CPU path and buying an FPGA SmartNIC tick-to-trade path, checking that the two latency profiles were measured on the same basis before comparing them.hft

H

hardware-timestamping-vs-software-timestamping-accuracyUse when deciding which layer's timestamp to record on a capture host, separating NIC clock divergence from UTC from kernel and user-space capture-path delay, and reporting capture jitter distributionally.solarflare

L

latency-arbitrage-defensive-order-sizingUse when a passive quote rests on a venue slower to reach than the one where price discovery happens, scoring the sniping hazard across the cancel latency gap and reducing shown size or widening the quote.adverse-selection latency-monitoring-percentile-based-slasUse when auditing captured latency samples against a percentile budget rather than an average, with nearest-rank P50 to P99.9 and a sample-count gate that refuses to certify on too few observations.percentiles

M

market-maker-vs-taker-strategy-classificationUse when auditing a strategy's own fill log to see what share of its flow added rather than removed liquidity, and attributing the exchange fees and rebates each side earned. Not a determination of regulated market-maker status.maker-vs-taker matching-engine-throttle-and-message-gapping-detectionUse when an order-entry session is counted against a venue message-rate limit and carries a session sequence number, pacing dispatch below the throttle and detecting inbound gaps before they become a disconnect.throttle-detection message-rate-limit-vs-latency-tradeoff-tuningUse when sizing the quote reprice interval for a strategy sharing a session with a message-rate ceiling, trading queue priority and adverse selection against the message budget. A parameter calculator, not a runtime throttle.latency-tradeoff microstructure-noise-filtering-for-hf-signalsUse when a high-frequency signal is built on the raw top-of-book midpoint and the midpoint is too noisy to trade, applying a local-level Kalman filter and an imbalance-weighted mid instead.microstructure-noise microwave-vs-fiber-network-links-for-cross-market-latencyUse when choosing or arbitrating between a licensed microwave path and fibre on a cross-market corridor, decomposing corridor latency into propagation, repeater and serialisation terms rather than quoting a propagation floor.fiber-optic

N

network-jitter-impact-on-strategy-performanceUse when a captured series of one-way packet delays must answer whether a link's delay variation is small enough for a latency-sensitive strategy, reporting percentile delays and jitter as a dispersion figure.packet-delay-variation

O

order-book-microstructure-signal-researchUse when testing whether a top-of-book signal genuinely leads the mid-price, computing order flow imbalance to the published definition including both queue-depletion branches. A windowed research audit, not a live generator.ofi order-to-trade-ratio-fee-penalty-avoidanceUse when unexecuted order traffic is subject to a venue order-to-trade ratio limit or surcharge, computing the count and volume ratios per instrument on the regulatory definition. The venue computes the official number.order-to-trade-ratio

S

strategy-latency-budget-decompositionUse when a strategy has an end-to-end tick-to-trade budget and it must be split across pipeline stages, checking the allocation is feasible and showing where optimisation effort actually pays.budget-allocation

T

tick-size-pilot-program-impact-assessmentUse when a minimum pricing increment has changed and the desk needs a measured answer on what it did to execution cost and queue position, rather than an inference from the tick ratio.tick-size-pilot tick-to-trade-latency-measurementUse when measuring how long your own box takes to turn a tick into an order on the wire, decomposing six capture points into five labelled stages with nearest-rank percentiles. Never run it on the hot path.tick-to-trade
