I was looking for a tool or resource that showed volume in a similar way as in the graphic below:

Graphic doesn't refer to real volume action, just a representation. Basically, I like to see buying and selling volume separately. Are there any tools or resources available that you can recommend?

Thanks in advance.
 
You can do this with eSignal studies - the one I use only captures live data though, so plots get lost if you close the tool and re-start.

Are you asking how to PLOTselling and buying volume (as different colours or +/- an X-axis)or how to IDENTIFY buying and selling volume? Virtually any charting product will provide the former - none that I know of, the latter.
 
Mr Bramble,

Good evening , Sir. How are you?

I’d like to chart buy and sell volume and whether these are opening or closing trades.

This evening finds me well, thank you for asking Mr. X.

You also would like this, no? Yes?

In all seriousness, and I suspect you already know, but for those that may not have considered this:-

What do think the price and volume would look like if the vast majority of trades were opening Shorts (no missus...) or opening Longs, or closing Shorts or closing Longs?

Where would the bar for this timeframe be (Y-axis) in relation to the previous bars?

And where would the open and close be within the range of that bar?

And what would the likely magnitude of the range for that bar be relative to the previous bars?

And what would the Volume likely be looking like for this bar and relative to the recent bars?

That’s the easy bit, when the majority of action is in one direction. But when you have a mixed bag of intent, you need to stand back a way and look at the bar in the context of the bars each side of it – yes, that means you don’t get a fix on ‘that’ until a few more bars have passed which means you will often miss the top/bottom. Which is absolutely fine in my book.

You want volume charting look no further (about half way down page)
the ensign rockets are a great feature too

Tony,

I'm afraid your trademark lucidity is lacking. I'm not sure what your saying.

Rols,

Impressive but not compatible with my feed. I'm sure it can't be that difficult (for programmers) to write a programme that links any feed with any charting package: "take the data from here and put it into here".

What are the main problems?

Grant.
 
rols,
Ensign Windows certainly looks quite interesting. I'll check it out. Thanks a lot.

Grant,

What instrument do you trade? I am curious as to how you expect to obtain the above data. For the instrument I trade (Which I expect, is the same for all instruments) there are 3 trade prices quoted - BID, ASK and LAST. These figures are fed into the brain and processed by the mind where the set of cognitive processes related to perception, interpretation, imagination, memories and experience yield a plan and ultimately a decision to act.
 
NT,

Thank you for the introduction to neurology. The reference to “opening/closing” trades was a flippant remark.

The 3 trade prices – bid, ask, last - can be expanded to the current 10 bids/offers and volume on the DOM, for example, for most instruments. I believe the full order book for Eurex products (my interest) is available, at a price, via Deutsche Boerse’s CEF data feed.

I won’t dispute your description of the thought process but the problem is that all the elements are subjective. Therefore, the conclusion may be suspect. It’s the “garbage in, garbage out” syndrome.

You’re well-informed re computing matters. Would you comment re one of my points?

“I'm sure it can't be that difficult (for programmers) to write a programme that links any feed with any charting package: "take the data from here and put it into here".

On a basic level, data can be fed into Excel via dde’s and then imported into a charting package via ascii or csv files, for example. I doubt whether this efficient.

Unfortunately, I suspect a few of my neurological connections are shorting.

Grant,

My comment was more aimed at the notion of charting BUY & SELL Volume. One cannot exist without the other. If 50 widgets were sold yesterday, isn't this exactly the same as saying that 50 widgets were bought yesterday?...Unless that was a flippant remark as well....

RE: My computer matters are self-tought, it isn't my profession. It's just a case of spending a few hours, days or weeks with your head buried in books until you end up with what you want. I recommend that you learn some Excel VBA (Visual Basic for Applications). Excel has good charting features and I'm certain you will be able to do what you want with it.

Also, here is a forum I recommend:

NT,

“If 50 widgets were sold yesterday, isn't this exactly the same as saying that 50 widgets were bought yesterday?”.

I’ve been grappling with this question and thought as you do – for every buyer there is a seller. But I think it goes deeper than this (we may be venturing into the realms of metaphysics).

Assume the price is currently 100. I’ll buy at 95, but you’ll only sell at 105. Am I buying to open (go long) in anticipation of a rising market, or buying to close (a short) to get out of a potentially deteriorating position?

Conversely, are you selling to open (go short), anticipating a falling market or selling to close (a long) to take profits or cut losses.

The price suddenly takes off and a sense of urgency/desperation enters into the equation. If I’m looking to open, I won’t chase the market, thus no trade. If closing, reluctantly I may have to accept your (high) offer. Hence, a trade.

Now your position. I doubt you would sell short on a rising price, so no trade here. If long, hold the position for further profit/reduced loss. Again, no trade.

Now assume the price takes a dive. I wouldn’t go long on a falling price – no trade. If short, I’ll hold – no trade.
You won’t chase the market to go short, so no trade. If you’re long, reluctantly you’ll have to accept my (low) bid, thus a trade.

So, is it possible to differentiate between willing and reluctant/forced buying/selling? (If I’ve confused bid and offer in this context, ignore it.)

Oh, no – not VBA. I bought a VBA book but suffer foreboding whenever I open it - the kind of book that once put down, you can’t pick up. The problem is trawling through almost 700 pages to understand the procedures and protocols for what are really simple solutions to simple problems. Or maybe the problems are actually complex and beyond my comprehension, namely how do I raw access raw data from my price feed – where is it? Thank you for link – I’ll certainly look at it.

I’m OK with Excel.

Grant.
 
It's not clear to me what this thread is about. There is no such thing as objectively measurable buy/sell volume. What you can measure and chart is the volume traded at bid and volume trader at ask. I've posted a couple of charts on this thread:

http://www.trade2win.com/boards/showthread.php?t=26750

What you can see from this is who is more agressive - the buyers or sellers - as shown by who is submitting marketable orders (market, marketable limit or stop) and who is submitting non-marketable limit orders. It is a matter for interpretation and context as to whether the market direction will continue or reverse.

If you are prepared to pay for it the MarketDelta product will slice and dice this data in more ways than you could wish for. Otherwise, I'm sure there's scripts for eSignal, Tradestation etc that wil allow you to chart it.

As to the question about adapting any charting/analytics software to any data feed. Yes, in principle possible. If you don't have the source code for the software then very difficult, verging on the impossible. So you are at the mercy of the software vendor to do it and support it. Even with the source code different feeds work in different ways and have their own quirks that will complicate the implementation. A standard protocol used by all vendors would be highly desirable. If they would all implement the FAST protocol that would be nice.
 
I'm afraid your trademark lucidity is lacking. I'm not sure what your saying.
'Trademark lucidity....'? :LOL:

I'm saying that it is possible to determine whether volume is primarily sell-biased or buy-biased by the range and close position on that range on the current bar and the volume profile of that bar within the context of those bars which exist prior to that bar.

You will also, often, need a bar ot two after your bar of interest to confirm your analysis.

Any clearer?
 
John,

Thanks for the link, mate. Seems to be some pretty good stuff here. Will certainly look at it all.

Cheers,

Grant.
