Here's how price turns down before we even explain it

A Rounding Top curves slowly like a dome, then the support level finally breaks down. A Bearish Pennant follows a sharp drop, tightens into a small triangle, then breaks lower.

A Double Top shows two equal highs, then price breaks down through the neckline support. A Descending Triangle has a flat ceiling and rising lows that squeeze tighter before breaking down.

A Bear Flag drops sharply, pulls back in a tight channel, then breaks lower again.
