Known Issues & Platform Limitations

Read this first

LO1 is licensed trading software that automates trade execution based on signals you configure. You are responsible for complying with all rules from your prop firm, broker, and platform providers. If your firm says “don’t do X,” and your account does X (even unintentionally), you can lose the account.

Important: The information on this page is provided for educational and informational purposes only. It describes examples of rules and behaviors that can occur given our trading system design and publicly available prop firm guidelines at the time of this publication. Prop firm and brokerage rules change frequently, and this page does not replace your responsibility to read, understand, and stay current with all rules from your brokerage and prop firm. You should confirm any questions directly with your prop firm or broker in writing — these examples are illustrative, not exhaustive.

Explanations and Examples

Micro + Mini exposure conflicts (MYM + YM)

Summary

During a recoup trade, the system may place trades on the YM contract even though the primary strategy operates on the MYM chart. In this context, the YM contract functions as a proxy — a larger, directly correlated instrument we use to accelerate recovery when specific conditions are met. This behavior is intentional and part of the recoup logic, but users may notice YM orders appearing alongside MYM activity.

Why this matters

Many prop firms limit or prohibit micro and mini contracts at the same time and cross-instrument hedging or mixed exposure. We provide these examples as informational references only. You are fully responsible for knowing what your specific firm’s rules are, and these examples do not cover all possible rules or future changes.

Examples:

  • Tradeify: prohibits mixing micro and mini positions, even same direction.
  • Apex Trader Funding: prohibits hedging/correlated exposure patterns.
  • Lucid Trading: prohibits hedging across contract types.
  • Alpha Futures: lists examples such as opposite exposure across mini/micro.
  • Legends Trading: Prohibited Conduct includes rules around improper trading behavior — traders must review the firm’s own official prohibited conduct page to understand specific constraints and confirm with Legends directly.

LO1’s recoup design intentionally avoids cancel/replace methods in fast markets to minimize execution fail risks, which can result in:

  • proxy instrument entries,
  • multiple exits fired in sequence,
  • and overlapping orders that might look unusual on a broker’s statement.
  • Note: Listings of these behaviors here are informational—they help explain why certain log patterns or fills may occur, not a guarantee of behavior under every condition.
  • Some firms interpret repeated orders (even if safe) as rule violations. You are responsible for configuring LO1’s settings (including disable canceling open orders) and ensuring firm compliance.

A broker may reject these if the position is already flat. Please read our Vantage Stack TradersPost Setup document, page 11, for details.

Educational note, not a rule interpretation: Prop firms vary in how they interpret rejected orders or rapid exit events—some ignore them entirely, others monitor suspicious order patterns. You must confirm this with your firm.

LO1’s news filters block or delay trading around configured events, as outlined in our Vantage Stack TradersPost Setup document, “News Controls” section.

These are not guaranteed to align with every prop firm’s news policies. Rules change frequently and you must match your firm’s stated timings and severities manually.

This section is informational — you need to:

  1. Confirm your firm’s exact news trading policy,
  2. Update the LO1 news configuration accordingly,
  3. Check regularly for updates to both your firm’s policy and to public news listings such as Forex Factory or FinancialJuice regularly.

LO1 automation depends on:

  • active broker tokens,
  • correct account links,
  • up-to-date alert clones, and
  • subscription settings correctly applied.

These operational issues don’t directly relate to prop rules, but can create unexpected orders or gaps that look like rule violations on a compliance audit. These notes help you understand what can go wrong, not whether a compliance breach has occurred. You must adjudicate that with your brokerage/prop firm.

Frequently Asked Questions

Why am I responsible for prop firm compliance if LO1 is automated?

Because your trading agreement is with the firm. LO1 is a tool; you alone are bound by the contract you signed and the rules stated by your firm. This FAQ provides examples but is not a replacement for your firm’s rulebooks.

Maybe. Some firms forbid such exposure; some allow it if not a hedge. Our examples show the types of rules commonly enforced. You must read your prop firm’s language and ask them directly to clarify terms.

No. Prop firm policies evolve. The rules listed here are informational examples only; you must review your own firm’s current documentation.

You are. This document explains known friction points and examples of rules that might apply, but does not guarantee coverage of all rules or future updates.

Each brokerage or prop firm posts and regularly updates their policies and rules. It is up to you to thoroughly review and understand how these rules affect your trading. This is a partial list, for informational purposes only, as rules frequently change and this list is only periodically updated. While we have a supportive community with experience understanding these rules,  please do not take take anything posted on our community Discord or our website as correct or comprehensive. You must always review rules directly from your brokerage or prop firm — these citations are examples only:

These links and references are given as examples of where to start your own review — because rules change and each firm may interpret them differently.
