You would need tick data to get true Volume at Price historically. However, since it's much easier to get 1 minute data for a extended historical period, the Profile Indicator in Investor/RT can take the 1-minute bars and allot the volume of each 1-min bar equally among the prices touched within that bar....resulting in historical volume profiles similar to that seen in the chart below. http://www.charthub.com/images/2008/05/27/HistoricalVolumeAtPrice.png You can view more volume-driven functionality of Investor/RT in this video: http://www.linnsoft.com/videos/volumeVolume/ And view a video on the Profile Indicator here: http://www.linnsoft.com/videos/profileIndicator/

Karim, When the crosshairs are on, the price level of the cursor is displayed on both the right edge of the horizontal line and the top edge of the vertical line, of the crosshair. Are you not seeing these prices? or are you saying you'd prefer to see the price right next to where the cursor is positioned? Regards, Chad

Karim, If I understand correctly, you're using the "Shapes" indicator to draw boxes on the chart. The problem you appear to be running into, is that the Shapes indicator is designed to draw boxes of a given width in BARS. So when you switch from a 3-min chart to a 5-min chart, the box is drawn across the same # of bars, but now the box covers more time because each bar covers more time. What you need is an option in the Shape tool to have the box cover a certain amount of time (in minutes), or to be given a specific ending time (similar to how it has a specific begin time). Let me know if I've correctly diagnosed your need here and I'll look into adding that option. Here are a few videos that will be of interest to you if you haven't already watched them: Drawing Tools in Investor/RT: http://www.linnsoft.com/videos/trendline/ Drawing Notes in Investor/RT: http://www.linnsoft.com/videos/notes/ Vertical and Horizontal Scaling in Investor/RT: http://www.linnsoft.com/videos/notes/ Regards, Chad

momentum, If I understand you correctly, you want a chart where the periodicity is range bars, and then those bars are drawn as equivolume bars. So essentially the height of each bar should be equal, but the width will be proportional to volume. Is this correct? If so, yes, and below is a screenshot. The normal range bars (candles) are drawn in the top pane ($1 rangebar of ES - those can be hidden if you like). The equivolume bars are drawn in the bottom pane. http://www.charthub.com/images/2008/05/15/EquiVolumeRangeBars.png

Actually just got started on TransAct/Infinity today. Shouldn't be long.

forsearch, Thank you for pointing that out. The problem is not our algorithm, but with a web page that has not been updated to reflect changes in the software. I have corrected the page. Over a year ago, we changed our logic for forming volume bars so that each bar is now composed of exactly the number of contracts/shares that the user requests (splitting trades up across multiple bars when needed to accomplish this). So the software does work as you desire, the web page was just out of date. Thanks again for bringing that to my attention.

Eagle, I can't help with Neoticker but anyone using Investor/RT or MarketDelta, simply add the Volume Breakdown indicator and choose "Time Per Bar (Secs)" as the result. You can see the number of seconds spent in each bar plotted as a histogram in the second pane of the chart below. http://www.charthub.com/images/2008/05/13/TimePerBar.png

Unless something has changed recently, I believe you can get 8 days of tick data from IQFeed, and 50 from eSignal...although I think IQFeed provides much more 1-minute data (maybe 1.5 years vs 6 months for eSignal). I have heard some discussion that DTN will be expanding their tick limit in the near future, but I don't have the details. If you really need years of tick data, there is a solution in tickdata.com. More information on pricing and how to pull tickdata.com data into IRT: http://www.linnsoft.com/tickdata/. You could purchase years of tickdata from tickdata.com, import that into IRT, and then continue to add another day each day from your realtime feed.

Take a look at the Trading System / Backtesting Videos on Investor/RT at www.linnsoft.com/videos. You can use Investor/RT with DTN IQFeed, and get 1.5 years of 1-minute data on ES (for instance) from DTN. Investor/RT will run you $79 per month for the Pro Backtester version. And if you need any help putting your system into Investor/RT, I'll be glad to lend a hand (I've been coding systems in IRT for 10 years).

This video details the Profile indicator which provides users with the ability to plot profiles (time/tpo-based or volume-based) on their traditional charts, of varying custom durations. Especially of interest to longer term Market Profile chartists. http://www.linnsoft.com/videos/profileIndicator/

VB and MP are still bundled, but I would expect that to change possibly June 1.

fs, Transact/Infinity is on our short list. I have everything I need from Transact to get started, and I'm looking to get started in the near future on this. I hope to have this working within the next month or two. Stay tuned. Regards, Chad

Mike, I apologize for not responding to this sooner. I don't recall getting an email notification. Anyway, plotting volume with a moving average is easy enough. Just add the Volume Analysis indicator with a smoothing periods, and add it to the same pane as the Volume (or drag and drop it into same pane after adding). Regarding the std dev bands....you want to draw bands around this average volume line, correct?....and using the standard deviation of the volume itself? This would require a custom indicator (and thus the Pro version of I/RT, which you may already have). The syntax for the custom indicators would be: VMA + STD(VO, 100) and VMA - STD(VO, 100) Here is a chart showing these bands on a 5-min chart of ES (day session only). http://www.charthub.com/images/2008/04/22/VolumeBands_2.png I used a 100 period smoothing in the VMA settings. Let me know if you have any questions. Regards, Chad

Simon, I'll give you a few tips on what you can do with I/RT as far as managing your symbol count. While IB might limit you to watching 100 symbols per day, I/RT has no such limit....it will allow you to monitor and scan whatever your datafeed (and/or your processor) will allow. DTN IQFeed allows you to monitor 1300 symbols realtime I believe. eSignal has 500 and 1000 symbol limits as I recall. So you can expand list of realtime scanned stocks by changing datafeeds, although I understand that might not be a decision you're willing to consider. Another option is monitoring 1,000s of symbols on an end-of-day basis, and then trimming that large universe down to a manageable number for realtime scanning. With I/RT's built in Yahoo! screener, and the ability to download historical data, current quotes, and fundamental data from Yahoo!, you can quickly build a large universe of stocks with daily and fundamental data. You can run a daily scan on some criteria to trim it down to 100 or less...mark those symbols for intraday....and then do your realtime scans during the session on that group. You can also use the Yahoo! "current quote" option to grab the current price quickly throughout the day on the larger universe of stocks if that would be of any use to you. Just a couple suggestions. And you have find more info on the Yahoo! functionality in I/RT at http://www.linnsoft.com/yahoo/. This is built into every version regardless of your data feed.

Here's an example of 6-month profiles on ES, but built with daily data: http://www.charthub.com/images/2008/03/19/SixMonthProfiles.png I'm only able to go back 1.5 years on 1-minute data on ES currently, but I'll see if I can dig up intraday data back to 1/1/6 tomorrow and share those charts with you.

MrPaul, When you say "Longer Term Profiles", are you referring to profiles of a 1 day duration, but of days 2 years back? or a single profile built off all the 30-minute bars of the last couple years (and encompassing the last couple years)? And when you say INDU and S&P, are you referring to indices or futures? I may be able to help you with any or all of the above combinations, I just need you to clarify.

So you want to essentially look into the future from each bar and grab the volume of the next bar, correct. Couple ways to do this. The easiest would probably be to use the MA (Moving Average) token/indicator. Set it up as "Simple 1 Period smoothing of Volume" and "shift left 1 bar". Let me know if you have any problems with that. Then, your syntax would be: MA < VO

You could also create IBH and IBL custom indicators and then use them for inside the Price Bands indicator to get this effect: http://www.charthub.com/images/2008/03/15/InitialBalance_2.png

Yes, I think this video TinGull shared will show you to transfer the IB direction from the MP charts: http://www.linnsoft.com/videos/tpo_lines_flash/index.html However there are easier ways to do this....using the Session Statistic indicator. But the exact settings for the indicator may vary depending on the session and periodicity of your chart. For a chart setup on day session (session 2 in IRT), you'd simply setup Session Statistics as "highest high of the first 60 minutes of the session" (and another for lowest low). This chart demonstrates this: http://www.charthub.com/images/2008/03/15/InitialBalance.png That's probably a little easier than transferring from and MP chart...and it has the advantage of not being dependent on the MP chart...AND it plots the IB historically so you can review IB on past sessions. However, if you're looking to plot alot of the other MP prices like VA, OR, etc...the method described in the video might be the way to go.

What periodicity would the chart itself be? Let's assume 1-minute, then you'd like to see on each 1-min bar, the high and low of the 60-min bar which contains that 1-min bar? Or would you like to see the high and low of the last completed 60-min bar? Or would you like to see the high and low of the 60-minute period of which that 1-min is the last minute (so highest high of last 60 bars essentially)?

I've create a video highlighting the volume-driven functionality in Investor/RT, including VWAP, Volume Analysis, MP Charts, T&S windows, VolumeBar periodicity, Volume-based trendline labels, bid and ask-volume quotepage columns, volume in RTL, and other volume-related technical indicators. http://www.linnsoft.com/videos/volumeVolume/

It's hard to tell specifically what's causing the difference in this case, as I don't know the logic & details behind the other program/chart, but there can be a few reasons. Since both charts are being fed by the same data feed, that rules out the fact that some data feeds package multiple trades together into one tick, while others don't. With tick-based (tikcbars), volume-based (volume bars), or price range-based (range bars) periodicities, the formation of the bars is highly on the date/time where the bars begin. Investor/RT has an option for "Continuous Tick & Volume Bars" in setup: prefs: charts: general window. When checked, tickbars can cross session boundaries. When unchecked, tickbars will begin fresh at the beginning of each session. If using the former, the view period of the chart determines where the bars begin. If using the later, the bars always begin at the start of session. And in turn, you can setup your charts on the day session (sess 2) or the globex sess (sess 2). Regardless, the underlying data is the same, but when you change the starting point of when you begin packaging that data into groups of ticks....then the bars will form differently. Hope that makes sense.

Here is a good breakdown of various periodicities, including tickbar: https://www.linnsoft.com/tutorials/periodicities.htm

I've just completed a video that demonstrates the global market playback feature of Investor/RT for anyone that might be interested. http://www.linnsoft.com/videos/playback

JJ, We don't have a specific drawing style for "High Low Close". If you right-click in a chart and choose "type"...you'll see the different drawing styles available. What I did in the chart below, and this might work for you...I made the style "High Low Bars" and then added dots at the close (using a 1 period Moving Average on Close and drawing as dotted). You can import the definition below if you like. http://www.charthub.com/images/2008/03/05/HLC_Bars_2.png
