Abuse, fraud and prohibited strategies
Copy trading, account sharing, latency arbitrage, cross-account hedging and the policies and evidence that keep payouts fair.
What types of trading abuse do prop firms face?
Common abuse includes copy trading one signal across many accounts, account pooling or sharing, paid passing services, hedging opposite positions across accounts or firms, latency arbitrage, tick scalping that exploits simulation, and exploiting price errors. Each produces payouts that real trading skill would not.
What is copy trading abuse in prop firms?
Copy trading abuse occurs when the same trades are copied across several funded accounts, often belonging to different people, so that one strategy collects many payouts. It concentrates risk, since a profitable signal pays out many times. Most firms prohibit copying third-party signals across funded accounts.
How do prop firms detect copy trading across accounts?
They compare trades across accounts for matching instruments, directions, sizes and entry and exit times within seconds, and cross-check with identity data such as KYC, payment details and IP addresses. Clusters of near-identical trades on unrelated accounts are the strongest signal.
What is group trading or account pooling?
Group trading or account pooling is when several people share one funded account, or one person trades accounts held in other people's names, to get around per-person limits or to combine resources. It breaks the link between the verified trader and the trading, which most firms prohibit.
What is latency arbitrage?
Latency arbitrage exploits the delay between a fast price source and a slower one: the trader sees a price move on a faster feed and trades on the slower platform before it updates, capturing near risk-free profit. In a simulated environment it exploits the simulator, not the market, so most firms prohibit it.
What is cross-account or cross-firm hedging?
Cross-account hedging means opening opposite positions on two accounts, at one firm or at two different firms, so that one account is likely to pass or profit while the other breaches. The trader effectively guarantees a pass at the cost of a fee. Firms prohibit it because it is not trading skill.
What is tick scalping, and why do firms restrict it?
Tick scalping means trading for very small price moves over seconds, sometimes many times a minute. In simulated environments it can exploit fill assumptions that real markets would not honour, such as always filling at the quoted price. Firms restrict it with minimum hold times or by reviewing such profits.
How do prop firms handle martingale and grid strategies?
Many firms restrict martingale and grid strategies because they increase position size after losses or add positions without stops, producing smooth equity until a sudden large loss. Restrictions usually come through rules on lot size, open positions, risk per trade and mandatory stop losses rather than a vague ban.
Should a prop firm ban expert advisors?
It depends on your platform and audience. Some firms allow expert advisors (EAs) and bots but ban specific strategies; others ban third-party or purchased EAs because many traders run identical copies. Write a precise policy rather than a blanket statement, and check what your platform supports.
How do I detect multiple accounts belonging to one person?
Match identity data across accounts: KYC results, payment cards and wallets, payout destinations, email patterns, devices and IP addresses, plus trading similarity. Many firms allow several accounts per person but cap total allocation, so detection is about enforcing limits rather than banning multiple purchases.
How do I prevent account sharing and paid passing services?
Prohibit third-party trading in your terms, verify identity before payouts, compare trading behaviour between evaluation and funded stages, watch for login patterns from different places, and rotate credentials when sharing is suspected. Paid passing services often show sudden style changes between phases.
What is a pass-for-hire service, and how do firms stop it?
A pass-for-hire service is a third party that trades a buyer's evaluation to pass it for a fee, then hands over the funded account. It breaks the purpose of the evaluation and usually leads to fast breaches or abuse later. Firms stop it with identity checks, behaviour comparison and terms that void such accounts.
How should a prop firm handle VPNs and location masking?
VPNs are common and often legitimate, so most firms do not ban them outright. They matter where they hide residence in a restricted country or link multiple accounts. Use KYC to confirm residence before payouts, and treat a VPN as one signal among several rather than proof of abuse.
How do I write a prohibited strategies policy?
List each prohibited strategy by name with a plain definition and an example, state how it is detected and what happens (profit removed, account closed, payout denied), and explain the appeal process. Prefer objective, measurable rules over vague phrases such as "unfair trading".
What evidence should a prop firm keep before denying a payout?
Keep the full trade history with timestamps, the rule or policy relied on, the analysis that links the trades to the prohibited behaviour, identity and connection data where relevant, and the decision record. Evidence must be strong enough to show the trader, a payment provider in a chargeback, or a regulator.
How do I balance abuse prevention with a fair trader experience?
Target specific behaviours with clear, measurable rules, enforce them automatically and consistently, flag grey areas for human review instead of punishing them automatically, explain decisions with evidence, and keep normal trading unrestricted. Traders tolerate strict rules that are clear; they resent vague ones applied after the fact.
