BLDP slipped below its $4.43 – $9.28 range and came back to test the low in the week of 21 Jan 2024.
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 week. The purple lines are the range the signal came from, and the green Retest label marks the week RangeStocks flagged. Tick “Show past sideways ranges” to see earlier ranges.
