Why Most Prop Firms Don’t Allow HFT
Infrastructure Requirements
True HFT requires co-location, premium feeds, and custom hardware. The cost is significant, which makes it hard for small firms to compete. Major exchanges sell co-location space and cross connects to reduce latency, and building a competitive stack demands heavy investment.
Regulatory and Risk Concerns
U.S. broker-dealers that provide market access must comply with SEC Rule 15c3-5. This means pre-trade risk limits, compliance checks, and monitoring in real time. The burden adds cost and complexity, especially for strategies that require very high message rates.
Market Abuse and Compliance Issues
Some strategies resemble manipulative behavior such as spoofing or layering. These are explicitly prohibited in U.S. futures law. Firms that want to avoid legal and reputational risks often choose to avoid HFT entirely.
What to Look for in an HFT-Friendly Prop Firm
- Latency and Execution: Consistent low latency and efficient smart order routing.
- Server Proximity and Co-location: Ability to colocate servers in the same data centers as exchanges.
- APIs and Tech Stack: FIX, native APIs, support for C++, Python, and hardware acceleration.
- Backtesting and Simulation: Access to nanosecond tick data and event-driven testing.
- Clear Fees: Transparent pricing for data, connectivity, and colocation.
Latency, Execution and Smart Routing
When microseconds matter, predictability is more important than raw speed. Traders need tuned networks, stable gateways, and intelligent order routing. On regulated markets, orders must pass through broker pre-trade checks required by SEC Rule 15c3-5.
Server Proximity and Co-location Options
Exchanges such as CME Group offer co-location packages. These include equidistant cross connects and connectivity within the same data centers where the matching engines operate. Any firm that cannot explain its colocation and connectivity strategy is not likely to be an HFT shop.
APIs, SDKs and Tech Stack for HFT
The best firms provide:
- Native APIs with efficient order management.
- Languages such as C++ or Rust for trading logic and Python for research.
- FPGA or DPDK options for hardware acceleration.
- Real-time telemetry with nanosecond precision.
Backtesting, Simulation and Replay
HFT depends on accurate simulations. Firms must provide deterministic replay of full order book data, nanosecond timestamps, and realistic modeling of exchange throttles.
Fee Structure and Payout Models in HFT
Employer-model firms pay salary plus performance bonuses. These firms do not advertise retail-style profit splits. Industry filings and news emphasize employee compensation structures.
Challenge-based props may offer high profit splits, but most prohibit HFT methods that depend on latency arbitrage or simulator exploitation.
Two Access Models: Employer vs. Challenge Props
- Employer-model firms: Provide their own infrastructure and hire traders directly. Compensation is salary and bonus.
- Challenge props: Offer funded accounts but usually ban HFT practices such as latency arbitrage. Apex, for example, explicitly bans HFT.

Retail Challenge Prop Firms and HFT
Most challenge-based prop firms forbid true HFT.
- Apex Trader Funding: Bans HFT and exploitative strategies.
- Topstep: Prohibits behaviors that resemble manipulative trading.
- FTMO: Allows algorithms if they are replicable but prohibits forbidden practices.
- FundedNext: Explicitly bans arbitrage and latency trading.
HFT Strategy Fit
- Market Making: Provides liquidity with tight spreads.
- Statistical Arbitrage: Uses microstructure signals to profit on short-term mispricings.
- Latency Arbitrage: Generally banned in retail props and sometimes treated as manipulative.
Connectivity Checklist
- Development: Backtest with nanosecond data.
- Staging: Simulations that mimic exchange throttles.
- Production: Co-location racks and direct cross connects. CME outlines such options in its official materials.
Costs You Will Face
- Market Data: Depth feeds and tick histories.
- Hardware: Specialized servers, low-latency NICs, and sometimes FPGAs.
- Co-location: Rack space and cross connects in exchange data centers.
- Personnel: Engineers, researchers, and compliance staff.
Risk Management for HFT
Key elements include pre-trade risk checks, throttles, kill switches, and surveillance. These are required by regulations such as SEC Rule 15c3-5 and CFTC rules on disruptive trading.
Due Diligence Checklist for 2025

Conclusion and Next Steps
If you are serious about Top Prop Firms That Allow High-Frequency Trading in 2025, focus on employer-model firms. They provide the infrastructure, compliance, and resources needed for real HFT. Challenge-based props are better suited for discretionary or systematic strategies that can be replicated in retail platforms.
Action Plan:
- Shortlist employer-model firms that fit your market interests.
- Prepare research notes, backtests, and coding samples.
- Understand compliance basics such as SEC Rule 15c3-5 and futures regulations.
- Practice interviews in coding, statistics, and market microstructure.

Yes, HFT is legal when conducted within regulatory frameworks. Prop firms that support HFT ensure compliance with relevant laws and regulations.
While challenging due to infrastructure costs, some prop firms provide the necessary tools and capital for retail traders to engage in HFT.
HFT is most effective in highly liquid markets like equities, forex, and futures, where price discrepancies can be exploited rapidly.
