Here are the 3 main charts I watch during the day. I also keep the 15 minute around, but these are the 3 constant charts up during the day.
I have marked a trade I took and the bar it was taken on each chart. You could have entered on any the charts for this one and made money.
I wish they had all been like this today. They weren't, losing day today.
