Hi David,
Petko suggests trading the top 1 to 3 performers. Petko has indicated in another topic he has never failed a challenge when trading the top 1 performer. He says it just takes longer.
Please keep in mind when you trade just the top 1 performer your account risk is limited to 1%. When trading the top 3 your account risk becomes 3%. Trading the top 3 performers can help you pass the challenge sooner but comes at a cost of increasing risk to 3%.
Alan,
