Technology and trading platforms
The software a prop firm runs on: terminals, rule engines, dashboards, price feeds and the questions to ask a technology provider.
What technology does a prop firm need?
A prop firm needs a trading terminal for traders, a back office to create and manage accounts, a rule engine that enforces limits in real time, a price feed, a trader dashboard, a website with checkout, a payment provider, KYC for payouts and a support tool. Most firms license the trading parts rather than build them.
What is the core software stack of a prop firm?
The core stack is a trading platform with simulated execution, a rule and risk engine, an account administration panel, a trader dashboard, a website with checkout, payment and payout providers, KYC, and support tools, connected by APIs and webhooks. The trading platform is the hardest part to build.
What does "trading platform" mean for a prop firm?
For a prop firm, the trading platform is the software traders use to trade and the server side behind it: the terminal with charts and an order ticket, the execution engine that fills orders against market prices, and account management. In most prop firms the execution is simulated rather than sent to a market.
What is a prop firm dashboard?
A prop firm dashboard shows a trader their account's progress against the challenge rules: balance, equity, profit target progress, daily and maximum loss headroom, trading days and statistics. Some firms build a separate web portal for it; some platforms include it in the terminal.
What is a prop firm CRM, and do I need one?
A prop firm CRM manages traders as customers: purchases, KYC status, account history, payout requests, support and affiliate attribution. It becomes valuable as volume grows. At launch, a help desk plus your platform's trader records and a spreadsheet can be enough.
What is a risk engine in a prop firm?
A risk engine is the software that evaluates each account against its rules: it calculates equity and loss levels as prices move, ends accounts that breach, refuses orders that break limits, and flags behaviour for review. In a prop firm it decides pass or fail, so its accuracy and timing are central.
How do MT5, cTrader, Match-Trader, DXtrade and TradeLocker differ for prop firms?
MetaTrader 5, cTrader, Match-Trader, DXtrade and TradeLocker are established trading platforms used by prop firms, sold through licences or white labels, with different prop features, price models and access rules. MetaTrader access for prop firms has been restricted since 2024. Most of them do not publish prices.
Why did MetaQuotes restrict MetaTrader access for prop firms?
In early 2024 MetaQuotes acted against prop firms using its platforms, reportedly over regulatory concerns about US clients. Brokers that had shared MetaTrader licences with prop firms were made to stop, and several firms halted trading or moved to other platforms. MetaQuotes did not publish a detailed public explanation.
Can a new prop firm still get MetaTrader 5?
Possibly, but access for prop firms has been tightly controlled since 2024 and typically requires a direct arrangement with MetaQuotes or a broker licensed to provide it for prop use, with restrictions on serving US clients. Ask the provider directly, in writing, whether prop evaluation use is permitted.
What is a grey label, and why is it risky for a prop firm?
A grey label is when a company uses a trading platform under another company's licence, typically a broker sharing its MetaTrader server with a prop firm, rather than holding its own white label. It is cheaper and faster, but the prop firm depends entirely on the licence holder, who can withdraw access at any time.
What is a trading bridge?
A trading bridge connects a trading platform to liquidity providers, routing orders from the platform to external markets and returning fills. Brokers use bridges for A-book execution. A simulation-only prop firm does not need one, because orders are filled internally against market prices rather than routed.
Does a prop firm need a liquidity provider?
Not for simulated accounts. A liquidity provider supplies real prices and executes real trades, which a simulation-only prop firm does not need. You do need a reliable live price feed. A liquidity provider becomes relevant if you decide to copy successful traders into real markets.
Does a prop firm need a broker?
Not necessarily. Many prop firms run entirely on simulated accounts and need only a trading platform with a live price feed. Some firms partner with a broker to obtain a platform licence, or to place real trades for selected funded traders. A broker is a choice, not a requirement of the evaluation model.
What is a demo server, and can a prop firm run on one?
A demo server is a trading platform server set up for practice accounts with virtual money. Some early prop firms ran challenges on brokers' demo servers. It works technically, but demo servers often lack prop rule enforcement and dashboards, and access depends on the broker's terms.
How is a simulated fill different from a real fill?
A real fill comes from a market or liquidity provider and depends on available volume, so large orders can move price or partially fill. A simulated fill is calculated by software from the current quoted price, usually at the bid or ask. Good simulators use live prices and real spreads so results stay realistic.
How should a prop firm simulate spreads and slippage?
Use the live bid and ask from a reliable feed, so the spread is the market's own spread, and avoid adding a markup. Model slippage conservatively or not at all, and apply the same logic to every trader. Inflated spreads or artificial slippage make challenges harder in ways traders notice and resent.
Which price feed should a prop firm use?
Use a feed from an established source with continuous coverage of your instruments, realistic spreads and good uptime, for example a major platform's feed, a broker or a market data vendor. Check symbol coverage, trading hours, history for charts, and whether the feed's licence permits prop use.
Should I build my own prop firm software?
Usually not at launch. Building a terminal, execution simulator, rule engine, admin panel and dashboard takes a skilled team months and ongoing maintenance, and correctness problems become payout disputes. Buy the trading core, build what differentiates you (website, community, CRM), and revisit building once you have scale.
How long does it take to build prop firm software in-house?
Building a production-quality prop trading platform in-house typically takes an experienced team many months, and ongoing work never stops. A minimal version can be faster, but the risk is in correctness and reliability, which appear only under real traders and fast markets.
What uptime should a prop firm platform deliver?
Aim for a platform that is available whenever your markets are open, with monitoring, alerting and a plan for outages. Downtime during market hours prevents traders from managing positions and creates disputes. Ask providers about their architecture, monitoring and incident history rather than relying on a headline percentage.
What happens to traders if the platform goes down?
During an outage, traders cannot open, modify or close positions, and their risk is frozen in place while the market moves. A good firm communicates quickly, reviews affected accounts, and reinstates or compensates traders whose accounts were harmed by the outage rather than by their own trading.
Do prop firm traders need a mobile app?
Many traders want to check positions and close trades from a phone, so mobile access matters. A responsive web terminal covers much of this; a native app is better for frequent mobile users and notifications. Most firms find a good browser terminal plus at least one mobile app sufficient.
Do traders expect TradingView-style charts?
Most traders are used to TradingView-style charts: candlesticks, multiple timeframes, smooth scrolling and drawing tools. A prop terminal should offer fast candlestick charts with common timeframes and enough history. Advanced drawing and indicators matter more to some traders than others.
Can traders use expert advisors or bots on a prop firm platform?
It depends on the platform and the firm's rules. MetaTrader supports expert advisors natively; many other platforms do not, or offer API trading instead. Firms that allow automation usually prohibit specific strategies such as latency arbitrage or high-frequency scalping, and some ban third-party bots entirely.
Which integrations does a prop firm website need?
A prop firm website typically integrates a payment processor, a way to create or assign trading accounts and send credentials, email for receipts and onboarding, analytics, a help desk or chat, KYC at payout time, and affiliate tracking. The account creation link is the integration most worth automating.
How does a prop firm connect checkout to account creation?
Usually through a webhook: when the payment provider confirms a sale, it notifies your server, which calls the trading platform's API to create or assign an account and then emails the login details. Without an API, someone does this manually from the admin panel.
How do I migrate traders from one platform to another?
Plan the migration around active accounts: let traders finish evaluations on the old platform or move them with their current balance and remaining limits, recreate account types and rules on the new platform, send new credentials, and communicate dates clearly. Move new sales to the new platform first.
What should I ask a prop firm technology provider before signing?
Ask about total cost at your volume (setup, monthly, per account, revenue share), contract length, which rules are supported and how each is calculated, how fast breaches are detected, what traders see, branding limits, API access, data ownership and export, uptime history, support, and what happens if the provider stops serving you.
What is a reasonable contract length with a platform provider?
For a new firm, shorter is safer: month-to-month or a one-time purchase without a term, rather than multi-year commitments. Longer contracts can bring discounts but lock you in before you know your volumes. Read notice periods and what happens to your data at exit.
Who owns trader data when I use a white-label provider?
Typically the firm owns its customer data and the provider processes it on the firm's behalf, but this depends on the contract. Check data ownership, export rights, how long data is kept after you leave, and whether the provider can use your data for its own purposes such as marketing to your traders.
