Here's a nifty little heatmap, compliments of NASDAQ. Updates every minute. 3 heatmaps are provided as defaults: ETF 100, Qs components pre-open and Qs components real-time. You can also create your own custom heatmap. If you've got multiple screens and daytrade the hot sectors, this is a quick visual tools that will show the real time change in RS as the cells realign themselves and change color reflecting market position. The default portfolio does not include the double/triple ETFs or their inverses, which is why the custom heatmaps are a nice feature.
