Select Prop Firm

What Is DCA Policy

A DCA policy refers to how a prop firm handles dollar-cost averaging, or the practice of entering a single trade idea in multiple parts over time. In trading, this means gradually adding to a position at different price levels instead of opening the full size all at once. While DCA is a common strategy in discretionary trading, many prop firms set restrictions around how it can be used to prevent traders from over-leveraging or gaming the system through rapid, fragmented entries.

Why Firms Restrict It

Firms implement DCA restrictions to ensure traders are not bypassing contract size limits, manipulating drawdown mechanics, or creating unmanageable exposure. Without a policy in place, a trader could enter a position in ten small increments that each appear compliant on their own but result in a much larger total position than allowed. This kind of behavior can create risk-monitoring challenges for the firm and undermines the purpose of contract limits and risk controls.

For example, if a trader has a maximum contract limit of six, they are not allowed to enter two contracts, then another two, then another two over the course of a few seconds as the price moves. While each order may be small, the sum total still reflects the full size and must remain within the stated limit. Firms that enforce a DCA policy expect traders to consider their total exposure across the position, not just individual entries.

Common Enforcement Rules

Firms typically track the total number of contracts held at any given time, including open and pending orders. Some may flag accounts if multiple entries occur too quickly, especially if they are spaced within seconds and clearly part of the same trade idea. Others monitor the cumulative impact of partial fills and scale-ins, especially when combined with aggressive risk or large stops. A trader who opens one contract every few ticks while price moves against them may not appear to violate contract limits on paper, but the behavior can still trigger a review if the exposure grows beyond what would be acceptable in a single entry.

Additionally, some firms disallow DCA altogether during the evaluation phase and only permit it in funded accounts with demonstrated consistency. Others allow it under the condition that all entries still respect the maximum allowed contracts at any given time and do not intentionally exploit slippage, system timing, or platform mechanics.

Practical Example

Suppose a trader is allowed to hold a maximum of six contracts on a $100,000 evaluation account. The trader enters two contracts on an initial pullback, then adds two more as the market dips further, and finally adds another two after a breakdown. Even if the trader enters these over thirty seconds, the total position reaches six contracts and is within the rules. However, if the trader adds a seventh contract by mistake or continues to average in as the loss increases, the account may be flagged for violating the contract limit or for intentionally circumventing the platform’s risk checks.

Even when the final position does not exceed the contract limit, some firms may still view overly aggressive DCA behavior as risky or inconsistent with the trading style they wish to fund. This is especially true if the entries are spread unevenly or if the average price creates a larger drawdown footprint than would result from entering the full position at once.

Summary

A DCA policy outlines how prop firms manage and restrict the practice of scaling into a position over multiple entries. While dollar-cost averaging is a valid strategy, it must be executed within strict contract size limits and without attempting to manipulate platform mechanics. Firms use this policy to prevent risk abuse, maintain execution fairness, and avoid exposure that exceeds account guidelines. Traders should understand how their firm defines DCA, whether it is permitted during evaluations or funded phases, and how to apply it without triggering violations. Managing entries responsibly and staying within total contract allowances is essential to staying compliant.
