What is a range retest, and how do I read the chart?

A stock moves sideways between a floor (the range low) and a ceiling (the range high) for a long time. Then it drops below the floor, fails to climb back in, and returns to test that low again. Traders also call this a spring. Some springs mark the end of a decline; many don't.

On the chart, each candle is one trading day. The purple lines are the range the signal came from, and the green Retest label marks the day RangeStocks flagged. Tick “Show past sideways ranges” to see earlier ranges.
