Consistency Rule: Lot Size Management

To ensure long-term capital preservation and professional risk management, FundedProFX requires all traders to maintain consistent position sizing. This rule is designed to encourage disciplined trading behavior rather than high-variance "all-in" strategies.

1. Scope of Application

Challenge Phase: This rule does not apply during the evaluation/challenge phases. Traders have full flexibility in lot sizing during their assessment.

Funded Stage: This rule is strictly enforced once a trader reaches the Funded Stage of all Account Types  . Compliance with these limits is a prerequisite for payout eligibility.
To ensure this renders perfectly in your Help Center (which likely uses Markdown or a standard Text Editor), I have simplified the formula so it doesn't rely on complex code that might break on certain web platforms.

2. Calculation Methodology

The consistency range is determined by your Average Lot Size, which is calculated during compliance reviews or at the time of a withdrawal request:

Average Lot Size = Total Lots Traded ÷ Total Number of Closed Trades

3. Operational Limits

All trades must fall within a specific range based on your average to be considered compliant:

Upper Limit: 200% of your average lot size.

Lower Limit: 25% of your average lot size (Average – 75%).

Example Calculation: If you have executed 10 trades with a total volume of 20 lots:

Average Lot Size: 2 lots (20 ÷ 10)

Upper Limit: 4 lots (200% of 2)

Lower Limit: 0.5 lots (25% of 2)

In this scenario, all trades must be sized between 0.5 and 4.0 lots.

4. Compliance & Payout Eligibility

Any trade executed outside of this calculated range will be flagged during the audit process. Maintaining a consistent lot size demonstrates professional floor management. Trades falling outside these parameters may lead to:

  • Removal of profits generated by non-compliant trades.
  • Delays or denial of payout requests.
  • Account review for inconsistent trading behavior.
