The KDJ indicator: A tool for your trading strategies

The KDJ, which many people call the stochastic indicator, is a great help for those looking to identify trends in the market. It appears on the chart as three distinct lines. K, the fast line. D, the slower one. J, sensitive to direction.

The first two show when something is overbought or oversold. The third? It shows the deviation between them.

How is it calculated? Very simple.

The KDJ works with the relationship between maximum, minimum, and closing prices over a specific period. First, the RSV (immature stochastic value) is obtained. Then smoothed moving averages are applied to arrive at the final values.

Reading the KDJ signals

K and D above 80? It seems we have overbought.

Below 20? Oversold. Simple as that.

When the lines cross, pay attention. The Golden Cross occurs when K and J cross D upwards - a buy signal, some say. The Death Cross? The opposite. A sell signal, perhaps.

Differences also tell stories. Price rising, KDJ falling? It might be time to sell. The reverse? Perhaps a buying opportunity.

Patterns that appear

See the W pattern. KDJ below 50. The weak market seems about to gain strength.

And the M pattern? KDJ above 80. The strong market may be preparing to fall.

Not everything is a bed of roses

The KDJ has its problems. Sometimes it triggers signals too early.

Other times, he arrives late to the party.

It doesn't work alone, poor thing. It needs friends (other indicators).

And what about those false signals? Many. Especially when the market is moving sideways or is nervous.

In the end, the KDJ is a cool tool. But it’s not magic. Use it alongside other analyses. The market is not an exact science. It never was.
