Capabilities

Every Fast-Trade Abuse Vector Covered

From minimum duration enforcement to latency arbitrage fingerprinting — the full spectrum of ultra-fast trading detection in one module.

Minimum Duration Enforcement

Set a minimum trade holding time — 10 seconds, 30 seconds, 2 minutes — per account phase. Trades closed below threshold are flagged, rejected, or counted against the account's violation score.

Tick Scalping Detection

Identify accounts repeatedly opening and closing positions within a single tick movement — exploiting micro-spread fluctuations rather than genuine market analysis across multiple instruments.

Latency Arbitrage Detection

Detect accounts exploiting price feed latency between your MT4/MT5 bridge and underlying liquidity — a sophisticated edge that simulates alpha but creates systemic P&L losses for the firm.

Trade Frequency Scoring

Score each account's trade frequency per session, per day, and per instrument. Accounts exceeding configurable thresholds are escalated automatically with an HFT risk rating for operator review.
Detection Patterns

Abusive Patterns We Catch

Multi-signal scoring across trade duration, frequency, price delta, and execution timing — no single indicator relied upon in isolation.

Critical

Sub-Second Trade Execution

Trades opened and closed within 1 second — indicative of automated HFT bots or latency-exploit scripts exploiting execution infrastructure rather than genuine market movement.
Critical

Price Feed Latency Exploitation

Consistent entry at stale price points followed by rapid exits at updated prices — a signature of latency arbitrage bots that exploit the gap between your bridge and LP feed timestamps.
Critical

EA High-Frequency Burst

Expert Advisor sending 50+ order requests per minute — characteristic of grid or HFT bots attempting to saturate execution bandwidth and exploit micro-movements algorithmically.
High

Tick Scalp Repeat Pattern

Repeated 1–3 pip profit extractions across 20+ trades per session with average duration under 15 seconds — exploiting spread and execution mechanics rather than directional market analysis.
High

News Spike Scalp

Trades opened within 1 second of a high-impact news release and closed within 30 seconds with outsized pips captured — a combined news + scalp violation caught by dual-module coordination.
Medium

Duration Threshold Gaming

Trades consistently closed just below the minimum holding period — e.g., at 58 seconds when the minimum is 60 — suggesting automated testing or intentional policy circumvention.
How It Works

From Entry to Enforcement in Milliseconds

A layered detection pipeline — every trade scored on open, flagged on close, and actioned before the next order lands.

1

Trade Open Timestamping

Every trade open event is timestamped at microsecond precision. The instrument, lot size, price, and account context are immediately ingested into the detection pipeline for real-time monitoring.
2

Duration Timer Start

A duration timer begins for each position and is compared against your configured minimum holding period. If the trade closes before threshold, the violation is logged and scored immediately.
3

Frequency Burst Check

Trade frequency is measured per account in rolling 1-minute, 5-minute, and 60-minute windows. Burst thresholds trigger an HFT risk flag and optional trade pause on the account immediately.
4

Latency Arbitrage Signal Analysis

Entry price is compared against the live LP feed timestamp delta. Consistent entries at stale prices with profitable exits at updated prices generate a latency arb score — escalated when score crosses threshold.
5

Composite Score Aggregation

Individual signals — duration, frequency, latency arb, pip delta — are combined into a composite HFT risk score. Once the account's rolling score exceeds threshold, enforcement is triggered automatically.
6

Account Action & Audit Log

Enforcement options include flag-only, account suspension, trade rejection, or profit nullification on violating trades. Every action is written to the immutable audit trail with full signal detail for dispute resolution.

Intelligent Scoring

Composite Score — Not a Single Rule

No single threshold causes a false positive. Each account's score is built from multiple corroborating signals — so legitimate fast traders are not penalised for one short trade, while systematic abusers are caught with precision.

  • Configure risk score thresholds independently for each evaluation phase
  • Score decay over time — one bad session doesn't permanently mark an account
  • Manual review queue with full signal breakdown per flagged account
  • Appeal workflow — cleared accounts have flags removed from compliance record

Scalping & HFT Detection FAQs

Everything prop firm operators need to know about detecting and restricting ultra-fast trading strategies in FXPropTech.

In a prop firm context, scalping refers to traders opening and closing positions within very short time frames — often seconds — to exploit micro price movements, spread fluctuations, or execution infrastructure latency rather than genuine market analysis. Prop firms restrict scalping because it creates systemic P&L exposure and is often combined with automated bots or latency arbitrage techniques.

FXPropTech uses a 6-signal composite HFT risk score combining trade duration analysis, trade frequency per rolling window, latency arbitrage scoring, pip delta pattern analysis, tick scalp frequency, and account behavior over time. No single signal triggers enforcement — accounts are scored holistically to avoid false positives on legitimate fast traders.

FXPropTech supports configurable minimum trade duration thresholds from 10 seconds up to several minutes, set independently per evaluation phase. For example, you can enforce a 30-second minimum for Evaluation Phase 1, 60 seconds for Phase 2, and 2 minutes for Funded accounts. Trades closed before the threshold are flagged, rejected, or scored against the account's HFT risk rating.

When an account's composite HFT risk score exceeds the configured threshold, enforcement actions trigger automatically. Options include flag-only (account flagged for review), trade rejection (future short-duration trades blocked), profit nullification on violating trades, or account suspension. All actions are written to an immutable audit trail with full signal detail for dispute resolution.

Latency arbitrage is detected by comparing each trade entry price against the live LP feed timestamp delta. When an account consistently enters at stale price points and exits profitably after the feed updates — a pattern inconsistent with human reaction time — the system generates a latency arbitrage score. Once this crosses the configured threshold, enforcement triggers automatically.

No. FXPropTech's composite scoring is specifically designed to avoid false positives. One short-duration trade or a single fast-execution session does not trigger enforcement. Scores include a decay mechanism — one bad session doesn't permanently mark an account. Accounts near thresholds are placed in a manual review queue with full signal breakdown before any enforcement action is taken.

Yes. Scalping and HFT detection applies across all instrument types including Forex pairs, metals, indices, energies, and crypto CFDs. Duration thresholds and frequency caps can be configured per instrument group, allowing tighter restrictions on historically abused instruments like XAUUSD while applying more relaxed settings on less volatile pairs.

Yes. Every scalping and HFT parameter — minimum trade duration, frequency caps per rolling window, composite score thresholds, and enforcement actions — can be configured independently for Evaluation Phase 1, Evaluation Phase 2, Verification, and Funded phases. This allows prop firms to tighten restrictions progressively as traders advance through the program.
