Checking the longer chart

A daily chart shows each day as one candle. A weekly chart shows each week as one, so the same share looks calmer and slower on it. KDJ works the same on both, but on the weekly chart it is built from nine weeks instead of nine days. It crosses far less often, and each cross covers a much larger move. People sometimes call this magnifying the chart: you step back to see what the daily wobble is part of.

The check

1. You see a golden cross on the daily chart.
2. Open the same share on the weekly chart.
3. If the weekly chart is falling, with lower highs and lower lows, and weekly KDJ is still pointing down, treat the daily cross as a bounce inside a fall. Wait.
4. If the weekly chart is rising, or weekly KDJ has turned up from a low level, the daily cross agrees with the longer picture. That is the case people act on.

The same check works for selling. A death cross on the daily chart, while the weekly chart is climbing strongly, is more often a pause than the start of a fall.
