Your trading day could end at 11 AM (Ad)

What do you usually do between 9:35 AM and 11:00 AM? Catch up on emails? Attend a meeting? Maybe grab a coffee? For me, it's become the most important part of my trading day. 85 minutes. That's usually all it takes. Set up at 9:35 AM… Check back at 11:00 AM. And when things work out, there's an extra $100 to $150 in my account… on a $1000 starting stake. Sounds too simple, doesn't it?
