In the previous lesson we considered day trading futures and in particular the ES Emini on the NinjaTrader platform using the volume relative strength indicator, and in this lesson, we stay on the same platform but move on to focus on ETFs.

In this case David has chosen the XLK ETF which is the technology sector.
