TSLA Ascending Wedge: what happens next

A rising lower trendline converging toward a flatter upper trendline — often a bearish reversal setup.

The honest historical base rate for the ascending wedge pattern, plus TSLA's current shape cohort. These are empirical base rates, not predictions. Chart shape predicts the size of the next move more reliably than the direction. Not financial advice.

Forward returns are measured from the detected pattern bar. Average confidence of detected ascending wedges: 0.62.

How a ascending wedge is detected

Also called a rising wedge. The detector fits regression lines through swing highs and swing lows over 180+ bars and requires the lower line to rise faster than a nearly-flat upper line (converging), with both lines fitting reasonably (R-squared >= 0.5). Textbook reads it as bearish; the base rate below shows what actually happened.
