Prop Firm Rules Explained: Complete Breakdown of Common Guidelines
Introduction: Why You Must Understand Prop Firm Rules
When entering the world of proprietary trading, one of the most important steps is understanding the guidelines that shape your experience. Whether you’re aiming to pass a challenge or manage a funded account, getting the prop firm rules explained upfront can mean the difference between long-term success and early disqualification.
In this guide, we break down the most common rules across evaluation phases and funded stages, with insights into how Larsa Capital structures its rulebook to support trader consistency.
Why Prop Firms Enforce Trading Rules
Prop trading firms operate with the goal of protecting capital and promoting responsible trading. Rules are not meant to restrict creativity but to:
- Prevent reckless risk-taking
- Maintain performance consistency
- Ensure fair evaluations for all traders
Understanding these guidelines helps you align your strategy and reduces the risk of unintentional breaches.
Key Categories of Prop Firm Rules Explained
Daily and Total Drawdown Limits
Most firms enforce strict rules on how much a trader can lose in a day (daily drawdown) and over the evaluation (total drawdown). Breaching these can lead to immediate failure.
Tips to stay compliant:
- Use stop-loss orders on every trade
- Set daily loss limits in your trading plan
Profit Target Requirements
Each phase of an evaluation challenge has a predefined profit goal. Traders must hit these targets without violating other risk parameters.
Example:
- Phase 1: 10% target
- Phase 2: 5% target
Minimum Trading Days
To prevent lucky streaks from skewing evaluations, firms typically require traders to be active for a certain number of days.
Best practice:
- Spread trades across the period evenly
- Focus on consistency rather than rushing
Consistency Rules
Many firms analyze the variance between your best and worst trading days to ensure consistent performance. Wide gaps may be flagged.
What helps:
- Balanced lot sizes
- Gradual growth in returns
Account Management Restrictions
Maximum Lot Size or Risk Per Trade
Some firms limit the maximum lot size per trade or restrict percentage risk. These measures reduce the chance of account blowouts.
Holding Trades Over News Events
Trading during high-impact news can result in volatility and slippage. Firms often prohibit this to minimize erratic outcomes.
Pro tip:
- Use an economic calendar to avoid risky timeframes
Overnight and Weekend Holding Rules
Rules vary, but many prop firms don’t allow positions to remain open over weekends or overnight to avoid gaps.
What to do:
- Close all trades by end-of-day Friday
- Use trailing stops if you’re near your target
Specific Rules in Funded Accounts
Passing an evaluation doesn’t mean you’re done with rules. Funded accounts often have:
Scaling Plans
Some firms increase account sizes for consistent traders. This comes with added expectations around discipline.
Profit Splits and Withdrawals
Rules define:
- When payouts are allowed
- Minimum payout thresholds
- Profit split percentages
Note: Larsa Capital offers flexible payout systems for its funded traders.
Technology and Trading Tools Compliance
Use of Expert Advisors (EAs)
Many prop firms ban or restrict automated bots. Where allowed, traders must use approved algorithms and avoid exploiting latency or arbitrage.
Copy Trading Prohibitions
Account mirroring or copy trading is typically not allowed, as it can circumvent fair trading practices.
Avoiding Rule Breaches: Best Practices
To stay compliant and increase your chance of success:
- Keep a detailed trading journal
- Revisit the firm’s rulebook regularly
- Use trade management tools to cap losses
- Ask support if a rule is unclear
Hidden or Overlooked Prop Firm Rules Explained
Sometimes traders fail not because of risk but due to small, technical violations:
Slippage Tolerance
Excessive slippage might invalidate a trade depending on the firm’s backend.
Login or Location Violations
Accessing your trading account from multiple IPs or countries may raise red flags.
Challenge Expiration Dates
Failing to complete the challenge within the time frame—even if in profit—can lead to disqualification.
