Hi Lee,
The FTMO Expert Advisors do not randomize trades. Having said that the same Expert Advisor will trade somewhat differently from one broker to another. This is because the historical data is not exactly the same from broker to broker. Even if you place the same Expert Advisor on two different charts with the same broker one of the charts may place a trade and the other may not place the same trade at the same time. This is because of the difference in the time it takes metatrader to send the order to the broker varies.
Congratulations on passing the evaluation stage!
Alan,
