Point-and-Figure Charting Explained

Friday, September 25, 2009
Point-and-figure charts (P&F) is another way to represent the price charts that can be used in Forex trading. Conventional charts display the price as the linear function of time, which results in a demonstrative picture of how the market behaved during certain periods of time. But the problem is that the trader often doesn’t need to know how price depended on time, all he needs is to know what the prevailing force on the market is at the moment — bulls or bears, demand or supply. That’s where P&F charts come handy. They show the price changes graphically, independently on the time during which the changes have occurred.

For example, the simple point-and-figure chart could look like this:



The green X’s are the price increases (by some certain value) and the red O’s are the price decreases. A column of X’s represent an uptrend, while the column of O’s represents a downtrend. In each given column there can be only X’s or O’s. When one trend ends a new column starts. As you see, there is no time scale in this chart. Each column can last an indefinite period of time.

So, how are these point-and-figure charts drawn? To start drawing a point-and-figure chart you should first set two important parameter values of the chart — the box size and the reversal distance.

The box size is the height of each of the O’s and X’s in pips. For example, if you set a box size to 10 pips, each X will mean an upward movement by 10 pips, so a column of 6 X’s is an upward movement by 60 pips. The same would be correct for the O’s.

The reversal distance is the amount of boxes that should be passed by a price in a reverse direction for a trend to reverse (to start a new column). The most common reversal distance is 3. That means that on a rising trend (a column of X’s) a price has to go down by the amount of pips in three boxes for a new column (this time — of O’s) to start. For example, if you use a box size of 10 and a reversal distance of 3: the price goes up by 60 pips, you draw 6 X’s, then the prices goes down by 30 pips (that’s more than 3 × 10), you draw 3 O’s down starting a new column from the level below the last X. If the price would go down by less than 30 pips you wouldn’t have to draw anything new. Basically, after drawing an X or O you just wait for the price to continue going in the direction for a box size of pips or in a reverse direction for a reversal distance * box size of pips.

If we consider 10 pips box size and reversal distance of 3 for the image above then we can say that first the price goes up by 50 pips during the first uptrend, then it goes down by about 50 pips, then goes an uptrend for 70 pips, then go two equal bearish and bullish trends for 30 pips (exactly the reversal distance). Then a price declines by 50 pips, then goes up by 30 pips and finally falls by 40 pips. It ends at +10 pips (if you sum up all the values) and, as you see on the picture, the ceiling of the final O is 10 pips above the bottom of the first X. That’s exactly +10 pips. The «effective price» is located at the bottoms of the X’s and at the tops of the O’s.

Using the point-and-figure charts is simple. Almost all chart patterns and analysis techniques that work with the classic time-based charts work with the point-and-figure charts too. The trends are very easy to visualize in the P&F charts because the square dimensions of the boxes (X’s and O’s) form nice 45-degree angle trendlines. Look at the example:



Apart from the chart pattern analysis, P&F charts offer a sort of trading signals. When the trend direction changes, a new position can be opened in this new direction with a stop-loss equal to the reversal distance. But such trading technique requires some thorough optimization of the box size and the reversal distance for the given currency pair and the market conditions.
