A Take A Look At Kagi Charts

As you can see from the Kagi chart below, the initial point that investors will certainly discover is that the lines on a Kagi graph differ in thickness depending on what the rate of the asset is doing. We'' ve also attached a routine candle holder graph to numerous of the Kagi charts to illustrate what the rate of the hidden property has actually done to trigger a certain change to the Kagi graph. At initially, a Kagi graph can seem like a complicated series of randomly placed lines, yet in reality, the motion of each line depends on the rate and also can be used to produce really profitable trading signals.

Luckily for traders, several charting and technical analysis techniques have been developed, which attempt to filter out random noise and concentrate on the important moves that act as drivers of an asset's trend. One particular method of filtering out this noise, which is also the focus of this article, is known as the Kagi chart. Although it is not the most common or widely known technical tool, it could be one to add to your toolkit.

Kagi Chart Construction

Kagi charts consist of a series of vertical lines that reference an asset's price action, rather than anchoring to time like more common charts such as line, bar or candlestick do.

As you can see from the Kagi chart below, the first thing that traders will notice is that the lines on a Kagi chart vary in thickness depending on what the price of the asset is doing. Sometimes the lines are thin, while at other times the lines will be thick and bolded. The varying thickness of the lines and their direction is the most important aspect of a Kagi chart because this is what traders use to generate transaction signals.

Kagis and Candlesticks

The different lines appearing on a Kagi chart may seem overwhelming at first glance, so let's walk through a historical example using Apple Computer Inc. (NASDAQ: AAPL) between May 8th and December 1st, 2006. We believe that this example will make it much easier to fully understand how this interesting type of chart is created. We've also attached a regular candlestick chart to several of the Kagi charts to illustrate what the price of the underlying asset has done to cause a certain change to the Kagi chart.

As you can see in Figure 2, the price of AAPL shares started to decline shortly after the start date of our chart. As the price fell, a vertical line was created, and the bottom of this vertical line was equal to the lowest closing price. If the next period's close were to be lower than the current bottom on the line, then the line would be extended to equal the new low. The line will not change directions until the price moves above the bottom of the Kagi line by more than a preset reversal amount, which is usually set at 4%, although this parameter can change depending on the security or trader's preference.

The Reversal

On June 1, 2006, AAPL shares closed above the Kagi low by 4.02% – more than the 4% reversal amount needed to change the direction of the chart (4%). As you can see from the chart below, the reversal is shown by a small horizontal line to the right followed by a vertical line in the direction of the reversal. The rising Kagi line will remain in the upward direction until it falls below the high by more than 4%.

The reversal was welcomed by many traders because this was the first bullish Kagi signal that was generated since the chart was created in early May. However, unfortunately for the bulls, the move was unsustainable as the bears responded and pushed the price below the high of the Kagi line by more than the reversal amount of 4%. The downward reversal is shown on the chart as another horizontal line to the right followed by a line moving in the downward direction.

As you can see from Figure 4 below, the bulls and bears spent the following few weeks fighting over the direction of Apple shares, causing the Kagi chart to reverse directions several times. Three of the moves higher that occurred between June and July were greater than 4% above the chart's low, which caused the Kagi chart to reverse directions. These moves represented an increasingly bullish sentiment, but they were not strong enough to fully reverse the trend.

The Thick Line

The number of false reversals started to show traders that bullish interest in the stock was increasing, but that the true trend remained in the bears' control. This story changed on July 20, 2006, because of a gap that was substantially greater than the 4% needed to reverse the chart's direction. In fact, the gain was large enough to send the price above the previous high drawn on the Kagi chart, shown by the most recent horizontal line drawn near $59. A move above a previous Kagi high like the one shown in the figure below causes the line of the Kagi chart to become bold.

A shift from a thin line to a bolded line, or vice versa, is used by traders to generate transaction signals. Buy signals are generated when the Kagi line rises above the previous high, turning from thin to thick. Sell signals are generated when the Kagi line falls below the previous low and the line turns from thick to thin. As you can see in Figure 6, the Kagi chart reversed directions after the sharp run up, but a simple reversal does not change the thickness of the line or create a transaction signal. In this example, the bears were unable to send the price below the previous low on the Kagi chart.

When the bullish momentum continued again in mid August, the price shifted back in the upward direction, creating a new swing low that will be used to create future sell signals. Ultimately, the bulls were unable to push the price of Apple shares back below the low, causing the Kagi chart to remain in a bullish state for the remainder of the tested period. The lack of a sell signal enabled traders to benefit from the strong uptrend without being taken out by random price fluctuations.

A Longer-Term Example

Now that we have an understanding of what generates a transaction signal when using a Kagi chart, let's take a look at a longer-period historical example using the chart of Apple Computer (April 30, 2005 – December 31, 2006). Notice how a move above a previous high causes the line to become bold, while a move below a low causes the line to become thin again. The changing thickness is the key to determining transaction signals as this fluctuation illustrates whether the bulls or bears are in control of the momentum. Remember that a change from thin to thick is used by traders as a buy sign, while a change from thick to thin shows that downward momentum is prevailing and that it may be a good time to consider selling.

The Bottom Line

Day-to-day price fluctuations can make it extremely difficult for traders in the financial markets to determine the true trend of an asset. Luckily for traders, methods such as Kagi charting have helped put an end to focusing on unimportant price moves that do not affect future momentum. At first, a Kagi chart can seem like a confusing series of randomly placed lines, but in reality, the movement of each line depends on the price and can be used to generate very profitable trading signals. This charting technique is relatively unknown to mainstream active traders, but given its ability to identify the true trend of an asset, it wouldn't be surprising to see a surge in the number of traders that rely on this chart when making their decisions in the marketplace.
