A demo account is a simulated trading environment that mirrors live market conditions without real money changing hands. Nearly every retail prop firm runs both its evaluations and its funded accounts on demo infrastructure - your $100,000 "funded" account is a simulation with a payout contract attached.

Why firms do it: simulation removes market risk from the firm's balance sheet, makes six-figure accounts cheap to issue, and lets hard rules - drawdown limits, consistency gates - be enforced automatically by the platform rather than argued about after the fact. The firm's revenue is your fee; your reward is paid from that revenue when the rules say you earned it.

What it means for you: fills and slippage may not match a live broker exactly, and the account can be closed for behaviour that live markets would tolerate. Neither point changes the maths of the split - it just sets the frame. Where real money does appear in the model: some firms promote top performers to genuine live accounts. Do prop firms use demo accounts? and the contrast in simulated vs live accounts.

Broker-side demo-account mechanics are described in MetaTrader's tester documentation.

Frequently Asked Questions

Why is a 50% drawdown harder to recover than a 10% one?

A 50% drawdown requires a 100% gain to recover, while a 10% drawdown only needs 11.1%. Recovery math is exponential. At 30% drawdown you need 42.9% to break even. This is why prop firms cap drawdown at 10-12% rather than higher percentages.

What is the 3-5-7 rule in forex?

The 3-5-7 rule suggests risking 1-3% per trade, keeping total open risk at 5% or less, and limiting single market exposure to 7%. It is a general risk guideline, not a prop firm rule, but following it naturally keeps you within most max drawdown limits.

What is a good maximum drawdown?

For prop firm trading, keeping your actual drawdown under 5% is excellent. Most firms allow 10-12%, but staying well below the limit demonstrates strong risk management and gives you a buffer for unexpected market events.

Is maximum drawdown calculated on balance or equity?

It depends on the firm and drawdown type. Static drawdown is typically calculated on starting balance. Trailing drawdown follows your highest equity. Some firms include floating losses in their calculation, making equity the relevant measure.

What happens when you breach maximum drawdown?

Breaching maximum drawdown results in immediate and permanent account closure. All positions are closed automatically, the challenge is terminated, and there is no refund or appeal. It is the final rule with no second chances.

What is the difference between daily drawdown and maximum drawdown?

Daily drawdown resets every day and limits your loss within a single session. Maximum drawdown is cumulative across the entire challenge or funded period. You can breach max drawdown through many small daily losses that accumulate over time.
