Volume / Price Analysis


Active member
Q. From Dr Iraj: “When buying volume increases the price increases. Very often there is a price increase while volume decreases. Why is this? Also, would you buy a stock, which exhibits the second scenario?

Generally speaking decreasing volume on an up day (NO DEMAND) is Bearish Volume.

If the volume is low and the price moves up (in nearly all cases) this has to be a false picture. The low volume is caused by the professional money refusing to participate in the up move, usually because the market is weak. The price is moving up, but it does not have the support of those traders that matter. This is a feature of a bear market – UP MOVES ON LOW VOLUME.

The reason for the non-participation of traders is because they have seen weakness in the background action. THEY KNOW THE MARKET IS WEAK.

If this price / volume action is seen with a trading range to the left it is a very strong sell signal. In most cases the mark up is quite deliberate.

It usually starts with a wide spread up but not too early so as NOT to cut you out of the market. This is often a deception to draw in as many ‘retail’ buyers as possible. Buyers are then ‘locked in’ by the inevitable sharp down move.


If there is a low volume (UP DAY) on the very first day of a break-out from a genuine accumulation area, the result is often a rapid one day UP MOVE on low volume.

This is NOT a sign of weakness. The wide spread up and out, on the first day from a genuine accumulation area, on low volume is caused by SHORTAGE OF STOCK.

Most of the supply has been removed by the professional buying at these levels. This LOW VOLUME UP MOVE out of an accumulation area is therefore an indication of STRENGTH.

Most up moves on low volume are a sign of weakness. Genuine NO DEMAND or low volume up-days always have market weakness in the background which the professional money has seen. During a bear market the volume is generally lower as prices fall, because there are fewer people trading. The professional money is not buying in sufficient amounts to make the volume even average, because they are bearish.

A MM or Professional Operator will NEVER fight the market. He will take advantage, if possible but will never fight it. If he does he will go bankrupt. If any up move occurs and he is still bearish, he simply withdraws from the activity. This is the cause of the low volume on the up move, (in other words he is not interested).

So, coming back to answer your quiz, the bottom line is this:

There are two primary causes of upward price on low volume.

1. = WEAKNESS and refusal of the smart money to participate. FALSE PICTURE

2. = Start of an UP MOVE after accumulation and lack of supply (SHORTAGE OF STOCK) after supply has been discretely removed at lower prices.

Finally, in answer to your last question, “would you buy stock which exhibits upward price on low volume”?

That is a judgment call. There are obvious (INCREASED RISKS) this is a critical time and it is easy thing to get it wrong as we have all experienced. The problem we face is deciding if genuine accumulation has taken place (START OF AN UP MOVE) or is it a no demand up move (BULL TRAP).

This research is based upon the book ‘The Undeclared Secrets that Drive the Stock Market’ by Tom Williams, 1993, Genie Software Limited. I still consider this book to be more advanced than any other publication on trading. The author Tom Williams is an old city trader who really knows about Volume/Price and Volume/Spread analysis, sometimes difficult to master his techniques, but a very potent text.


Please bear in mind the following statement, “VOLUME IS THE MOST IMPORTANT FACTOR IN TRADING” (Dr Iraj)

Thanks, I bought the book some time back on the UK-Invest bookshop about £40

Does the author give any indication of volume patterns BEFORE the upmove, ie any chance of recognising if it is good or bad

Hi mate, I think this is a judgement call. The way I see it, when a stock is subject of accumulation the professional operator will sell pockets of stock to force the price down, which of course induces weak holders to sell, in turn making stock available at the price he wants to pay. This can easily be done when the stock is weak. This can go on for some considerable time until the floating stock is removed from the market. Then the MM begins to test the supply in the market by gapping down, which we see all of the time. If many sellers appear then the stock is not ready to rise. Joe public starts buying as the price rises higher and the smart money has entered the distribution phase, selling at a profit and so the cycle goes on. I think we have more going for us these days with access to L2 or daily trades history on the likes of ADVFN to allow us to make the correct judgement. I am not sure this has answered your question, I am not aware of any patterns that identify the type of volume but I hope this helps.

Does anyone has a copy of "The Undeclared Secrets that Drive the Stock Market’ by Tom Williams" that are willing to sell?

If they're 'undeclared' and secret', it's unlikely.

But I do have an e-book "The Secret Fibonnaci Numbers from His Matrix that Time forgot, but call it £40 and it's yours" if you're interested.
A highly amusing reply but the Tom Williams but is the only book I want at the moment thanks.

Start here where the advice is free :

Then: An old web site of Tom Williams:http://www.tradetowin.com/

And the successor:http://tradeguider.com/Support.asp
( Cannot see the book here albeit bookseller page is being re-built)

Other links:

Tom Williams Book - Genie Software

I have two copies, but I'm afraid they are not for sale - far too valuable. The original was published by Genie Software Ltd in 1993. I have a telephone number 01273 771865 and fax 01273 329160 with an email address of : [email protected] and web address www.TradeToWin.com. I have no idea whether these are still live. I have a vague idea that the company and software VSA were bought out by an American company. If you try searching for VSA or VSA5 or Volume Spread Analysis, you may find them, or Tom Williams or even Genie Software.

Hope this helps

Kind regards

Let's not cloak all of this in mystery yet again. See http://www.tradetowin.com/default/intro.php for info on obtaining the book (which goes for less than 50 pounds).

However, much of what is in the book is available in the PV Forum for free to those who look for it.

You may also be able to talk somebody who has a pdf copy into giving it to you for nothing, though this is illegal.

I'm sure that many of my posts here on T2W contain poor grammar and lousy spilling, so any criticism by me of others on this front is akin to the pot calling the kettle black. That said, if I had a web site promoting my outpourings, I'd like to think that I'd take the necessary time and effort to ensure that the opening sentence on the home page didn't contain not one, but two, very basic gaffs:
"This book will help you under the stock market the easy way. The information will be a starting revelation to most readers."
I might be missing out on a plethora of insights into the complex world of price / volume analysis, but that's a risk I'm happy to take. On this basis, I won't be buying this book anytime soon.
