[ Industry challenges ]

What a bug costs on a trading platform

The failures brokers and trading startups bring to us most often. In trading, a defect has a dollar figure attached.

01

Orders that fill wrong, or not at all

A market order at the wrong price, a stop that doesn’t trigger or a partial fill shown as complete. Traders notice in seconds.

02

Prices that lag or freeze

A stale quote during a news spike means trades at prices that no longer exist, and complaints that follow.

03

Margin and P&L that don’t add up

Wrong leverage, swap or margin-call levels close positions early, or leave the broker exposed.

04

Deposits and withdrawals that stall

Funds that don’t credit, or a withdrawal stuck in review, lose trust faster than any losing trade.

05

Outages at market open and on news

Volume spikes at the open, on rate decisions and on viral moments. That is exactly when platforms fail.

06

KYC, AML and jurisdiction gaps

A sign-up from a restricted country, or a missing risk warning, puts a licence at risk.

[ What we test ]

Testing mapped to the trade lifecycle

Each practice is pointed at a moment in a trader’s journey, from sign-up to withdrawal, and links to the full service.

Most critical

Orders, execution & positions

Market, limit, stop and OCO orders placed, modified and cancelled end to end, with fills, positions and history checked against the server.

[ Test scenarios ]

The checklist behind every release

Pick an area to see the scenarios we run, and the client platform where they matter most.

[ Compliance & standards ]

Tested against the rules your platform answers to

Brokers, exchanges and new market products all face regulators and auditors. We test the controls and hand over evidence your team can use.

KYC · AML · sanctions

Identity checks, document upload, screening and restricted-country blocking tested against your onboarding rules.

Broker & market regulation

Risk warnings, leverage limits, client-money handling and disclosures for the regulators you answer to. We test your controls; we don’t give legal advice.

SOC 2 · ISO 27001 · PCI DSS

Access control, audit trails, encryption and card handling tested, with evidence your auditors can use.

Data privacy · GDPR

Consent, data access and deletion requests, and what trader data each role can see.

[ Case studies & results ]

Two trading platforms, from regulated broker to new market

A multi-asset broker and a real-time sentiment market. Different products, the same need for prices and balances traders can trust.

The challenge

A regulated broker offering forex, metals, indices and commodities on margin. Leveraged trading leaves no room for a wrong price, a wrong margin level or a slow withdrawal.

What we test

  • Order types, fills and position history
  • Spreads, swaps and margin calculations
  • Client portal sign-up, KYC and verification
  • Deposits, withdrawals and account funding
  • Risk warnings and restricted-country rules
  • Web and mobile parity

The challenge

A live, dollar-priced index of public figures’ cultural relevance, traded with long and short forecasts against a bonding-curve pricing engine and funded in USDC.

What we test

  • Long and short forecasts opening and closing
  • Live index pricing against the pricing engine
  • Short liquidation thresholds
  • USDC deposits and withdrawals on Solana
  • Wallet connection on browser and mobile
