Each day a stock draws one bar on its chart. Sixteen of those shapes have names, and traders watch them for signs a move is turning. Every stock in the scan universe is checked after the close — and only listed when the prior trend supports the shape and volume backs it up.
The board
Each trading day, a stock draws one small bar. The thick part shows where it opened and closed; the thin lines above and below show the highest and lowest price it touched. Green means it closed higher than it opened, red means lower.
Read a few of these bars together and you can see who was winning. A long lower wick means sellers pushed price down and buyers took it back before the bell. Certain combinations repeat often enough that traders named them — that's all a "pattern" is.
None of them predict anything on their own. They describe what already happened, which is why this scan also checks the prior trend and the day's volume before listing a stock.
A candlestick pattern describes who won a session, not what happens next. A hammer says sellers pushed price down and lost it back before the bell. Whether that matters depends entirely on what came before it — which is why this scan checks the twenty-day average first and discards formations that appear mid-drift.
Treat it as a shortlist. Stocks marked Confirmed traded at least 1.2× their usual volume, meaning the move had real participation behind it rather than a thin book. Those are worth opening a chart for. The rest are worth noting and nothing more.
Each pattern links to a page explaining how the formation works, when it commonly fails, and every stock in the scan universe currently showing it.
