# How to Test a Strategy on a Demo Account First

Testing a strategy on a demo account before committing real capital is standard advice. What is less commonly explained is how to structure the demo test to produce conclusions you can actually rely on.

## The Purpose of Demo Testing

Demo testing serves two purposes. First, it validates whether the strategy produces positive expectancy in current market conditions. Second, it gives you practice executing the rules without financial pressure.

Both purposes require that you treat the demo test as seriously as live trading. If you manage the demo account differently from how you would manage a live account - taking riskier positions, ignoring stops, adding more capital when it runs low - the test tells you nothing useful.

## Setting Up the Demo Test Correctly

**Use realistic account settings.** Your demo balance should approximately match what you intend to trade live. Testing with $100,000 demo and planning to go live with $5,000 means your lot sizes, position count, and everything else are scaled wrong.

**Apply the same risk rules.** 1% risk per trade, daily loss limits, maximum position count - all the same as live.

**Trade the same instruments and sessions.** Do not test on instruments you would not trade live.

**Connect Trader Journal to the demo account.** The EA sync works identically for demo accounts. Connect the demo MT4/MT5 account to Trader Journal as a separate account. Track the demo results in the app with the same journaling rigor you would apply live.

## The Duration and Sample Size

A valid demo test requires:

**Minimum 60 trading days** - enough time to encounter different market conditions (trending periods, ranging periods, high-volatility news weeks).

**Minimum 80-100 trades** - enough to see statistical patterns. If your strategy generates 3 trades per week, 60 days produces approximately 36 trades - not enough. Extend the demo period until you reach 80-100 trades.

## What to Evaluate at the End of the Demo Test

Run these assessments in Trader Journal's Reports tab:

1. Net profit factor (after simulated spread costs - demo spread is often different from live spread)
2. Win rate stability month-over-month
3. Maximum drawdown
4. Execution quality (your star ratings throughout the demo period)

If profit factor is above 1.3, win rate is within 5 percentage points of your expected rate, maximum drawdown is within your tolerance, and your execution quality (star ratings) is consistently 3+, the strategy passes demo validation.

Proceed to small live positions after successful demo testing. Track both accounts in Trader Journal to compare live vs demo performance.
