Two new resistance levels formed for PLTR in February, with both being defined by falling windows in PLTR's stock chart.
The first falling window occurred on 2/16, where the high for the day occurred at $30.44/share. It was around this price that the stock's second attempt to rally (after correcting from its earlier highs) ran out of steam on 2/22. Ultimately the stock's second attempt to rally only spanned a single trading day, with the stock managing to climb 15% to the close on 2/19.
After the stock's second attempt to rally ended on 2/19, the stock corrected an additional 22% to the close on 3/8, which spanned 11 trading days.
The stock's third attempt to rally brought the stock up 20% from the close on 3/8 to the close on 3/12, which spanned 4 trading days. This rally ran out of steam in the falling window defined by the candle back from 2/18. This resistance level remained in play even until July where the stock's rally ran out of steam at this price on 6/28.
