How to Review Prop-Firm Rules for Algorithmic Trading

Begin by identifying the exact account. An evaluation account can have different objectives and restrictions from a simulated funded or live funded account. Some firms grandfather terms or maintain separate programs. Record the program name, account stage, policy URL, access date, and any version or effective date shown on the page.

Then describe the proposed method in operational terms. State whether signals are generated automatically, orders are routed without confirmation, trades are copied between accounts, accounts belong to one person, and a third-party strategy is used. Policy labels can be broad, so a concrete description produces a more useful compliance answer.

Risk rules often depend on account state. A trailing threshold may move according to a method defined by the firm; a size limit may change after milestones; and a daily boundary may use a specified time zone. Do not recreate formulas from memory. Use the dashboard and current official examples, then independently test your calculation with safe hypothetical scenarios.

Policies from Topstep, Apex Trader Funding, My Funded Futures, Tradeify, and Earn2Trade illustrate why firm-by-firm review is necessary. Their published pages address different account parameters, prohibited activities, and copy-trading conditions. Do not blend those statements into an industry-wide rule. The source for one program does not authorize behavior at another.

Map the actual topology: signal source, leader account, follower accounts, owners, firm programs, execution platform, and operator. A copier can reproduce valid orders while still violating a restriction on account coordination or external signals. Conversely, a firm may permit some copying among a trader's own accounts under stated conditions. Only current firm policy resolves that question.

Topstep publishes API-access information, while other firms publish explicit copy-trading or fair-play pages. These technical and policy documents serve different purposes. If any combination is not addressed, send the firm a concise written scenario and retain the response. Avoid asking only whether a named tool is supported; ask whether the precise behavior is permitted.

A strategy stop is not the same as an account drawdown control. Several open positions can gap, protective orders can slip, and copying can multiply exposure. Set account and group caps outside individual strategy logic. Avoid sizing to the published threshold; retain a buffer chosen by your own risk policy because rule calculations and realized losses can move differently.

Time-based rules require one time-zone source and a maintained event procedure. If a firm restricts news trading or holding through specified periods, define how events are identified, when new entries stop, and how existing positions are handled. Calendar feeds can be late or revised, so manual review and fail-closed behavior may still be necessary.

CME Rule 575 addresses disruptive practices, including specified conduct involving order entry and cancellation. Prop firms may impose broader fair-play standards or restrictions designed for their programs. Compare the algorithm's actual order logic with all applicable layers. Pay special attention to rapid cancellation, account coordination, latency exploitation claims, and strategies designed around platform artifacts.

Keep enough logs to explain intent and behavior: signal, order instruction, broker acknowledgement, modification, cancellation, fill, account, and operator intervention. Logs do not cure prohibited conduct, but they support review and incident response. If a method's legitimacy depends on concealing its operation or exploiting a technical flaw, do not deploy it.

Use two-person review when practical. One person maps the rules and configuration; another follows each source and challenges the interpretation. Capture screenshots or PDFs where terms permit, but keep the live URL because archived text can become obsolete. Set a short review interval for rule-sensitive content rather than treating this article as permanent authority.

Finally, separate compliance from expected economics. Passing an evaluation or receiving a payout is never guaranteed. Automation can repeat mistakes as efficiently as valid instructions, and futures losses remain possible. The objective of the review is to establish current permission and controls—not to imply that a firm will accept every trade or that the strategy will succeed.
