Demand Index ( DI )

Demand Index was invented by James Sibbet

A detailed guide to the many methods of using Demand Index provided by Precision Trading Systems


Demand Index is the creation of James Sibbet, and uses complex code to make simple work of the interpretation of volume and price as a combination. Understanding volumes is never an easy task but this beautiful piece of programming certainly makes like a lot easier.

There are several ways in which this indicator can benefit traders and investors to determine how markets will behave in the near future .


Having studied many technical indicators over the years I have formed the opinion that Demand Index is one of best for finding meaningful divergences.

If the price of the market is making a new high and the Demand Index is not this is known as a bearish divergence. There are several drastic photos below showing extreme cases of divergences to help you understand what to look for.

Trend detection

The crossing of the zero line is an indication of net selling or buying over the length you have specified, it must be noted that in this manner the indicator is acting as a lagging indicator and longer lengths are required with some smoothing to give meaningful results.

Notwithstanding the above it is important to understand the difference between a "real crossing of zero" trend change move and a false signal.

If Demand Index is hovering and fluctuating around zero it does not generally mean much, but a decisive break though which stands out is the kind of move that one needs to look for.

Break outs

When a range or tight congestion area can be seen in the Demand Index indicator it is well worth noting that when a break out from this range occurs, it will likely be followed by a break out in the same direction of the underlying market.

As with the above it is also important to know the difference between noise and a real break out pattern, this must be an obvious observation and if you have to spend time asking yourself if it is real or not then it probably is not a good signal.

Prediction of next movement

When an extreme peak in Demand Index occurs it implies serious buying and this is usually followed by one more move up from the market. There is a photo lower down the page showing an example of this.

Extended divergences over a period of time

When a market continues to trend down and the Demand Index continues to trend up this is a sign of a major bottom forming and vice versa.

This indicator often works better with longer lengths such as 30, 50 or 100

To make interpretation simpler a smoothing feature has been added to Demand Index

Below length 80 with smoothing 12 shows the downtrend starting and stays below 0 as the price declines

Demand Index length 100 below having a monster divergence with the price AND an extreme peak

As stated above, the extreme peak signals a single higher peak is coming

The divergence thereafter calls it a bearish move ahead

Below is an example of a bullish divergence with a lower low on the market price of a 5 minute chart of the French CAC 40 and a higher low on the Demand Index when looking at the same time.

Another example of the future price direction of the SP500 futures being predicted by Demand Index

Notice how well it correlates with what happened in the market, but shows it BEFORE it happens.

One must not become deluded and expect this to predict the future, a better outlook is to use the analogy of cloud examination.

How do we establish if it going to rain?

We look to see if there are clouds, if there are we look to see the colour they are.

If the clouds are grey or black then we can reasonably expect a strong probability of rain soon.

Demand Index advance warning

Realising the power of Demand Index divergences they became one of the key components of the Precision Index Oscillator below

Below: The extreme peak in Demand Index heralds a clear warning that prices will move higher soon.

Then follows a new peak in the market, but the Demand Index does not make a new peak, indicating a bearish divergence is happening

Below: The extreme dive in the Demand Index indicator shows a big move down is likely.

Below: Demand Index indicator crossing the zero line gives a clear and reliable indicaton of up trend or down trend.

e can see the effect of increasing Demand Index length to 100. Notice the smoothed line give us clear trend definitions.

The new low made at 20:00 was not confirmed by Demand Index low which is a bullish divergence. Notice also how after this the indicator just keeps rising showing us that volume accumulation is occurring. The minor sell off at 0850 does not transmit into the Demand Index as the volume was low. The move at the end of the data is backed up by a huge move up in the Demand Index Indicator, which illustrates the validity of it.


The photo below shows a simple and effective divergence in the Demand Index which led to a nice rally
