@Draw Min/Max Spread: Thanks! Very useful indicator. Pepperstone has a spread of  0.1/0.4  now btw.  
@Accumulative Bid/Ask Volume (ZigZag): OK, I think I understand now when I looked at your image again. That would mean a continuously resetting volume count whenever there is a confirmed zigzag high/low (which I implemented) but also a retroactive change over two zigzag high/low periods. That is going to be very difficult to implement. As I said the zigzag is not what it seems on the chart. I now even think the current implementation is buggy as it still contains all the temporary high/low values but these are still somehow ignored anyway. I tried to understand the algorithm's internals but must say that I failed.  
@Accumulative Bid/Ask Volume (ZigZag): Upon further inspection I noticed that my volume plot is not in sync with the ZigZag line on the chart. It leaves much to be desired. This is due to the ZigZag filter I had to implement, which still doesn't produce a useful result from the ZigZag. I consider it now as strictly beta and unfinished. There is not one single ZigZag indicator that produces a useful result. It looks like they all have the same problem: They all repaint (which is not the biggest problem because my accumulated volume repaints, too) and the output array is full of garbage and remnants of old calculations. I'm giving up on this one for now. There is no way I can make it work without programming a better and more useful zigzag indicator. Don't install if you need perfect results.  
@Bid/Ask Volume: I wrote: I also generally tend to only mildly trust known indicators that have been used ad nauseam and have already been around for decades. Usually I find them to be useless and that's why they are put out for free for everybody's use. I have to correct myself here. I don't mean my own indicators that I put out but generally the vast majority of the indicators that can be found on the net (that I have come across at least). They are usually free for a reason and have been deliberately placed in my understanding.  
@Bid/Ask Volume: New version out Added save feature for backfill of collected data and filter for very high volume.   @

(v 1.01) This is the Accumulative Bid/Ask Volume (ZigZag Edition). To operate it successfully please download and install the ZigZag indicator from here: /algos/indicators/show/157 If you are using my other Bid/Ask Volume indicator you must turn off the "Write to file" option on one of them otherwise two indicators will write to the same data file leading to corruption and/or twice the volume.   02.06.2015 - Version 1.01 Corrected a flaw where once the repaint is triggered it would do so for the whole duration of that bar   Note that the actual ZigZag indicator line in the example image is not part of the volume indicator's plot. It is applied to the chart only for demonstrational purposes. The ZigZag is still needed for the indicator's inner workings. It can also be applied for guidance in finding reasonable settings.    
Bid/Ask Volume
free  29 May 2015
(Version 1.1) Accumulates and displays the true bid and ask volume in monetary terms (currency units) for each bar/period and their difference in a convenient histogram plot. It features filters below and above which all volume is filtered out to calculate with only the high volume offers (the smart money in theory, as opposed to the "suckers"). Due to its nature having to collect the data first it does not provide a full backfill. However, it provides a backfill for self collected data with its new data saving feature. For this an automatically named text file in the current user's documents folder is created. The file can be manually named if necessary. It is best to leave the respective option empty in the settings. Switching to another timeframe, reloading the chart or changing the volume settings occurs now with only minimal loss of collected data depending on the save setting. No more emotional meltdowns because the chart application disconnects from the server and restarts the indicator plot with the loss of all collected historical data. To compare filter settings that are right for the broker, chosen currency pair and the time of day multiple instances of the indicator that access the same data file can be attached to the chart. In this case only one instance of the indicator should actually write to the file and collect data. Data writing must therefore be turned off in the other indicator's instances. The interpretation of the plot is up to the user. Some people use it to identify high volume turns and impending directional change. Other people use the difference plot as direct signal. Or it may not yield anything at all and may only be used for educational purposes. This seems to be highly dependent on the type and quality of volume delivered from the broker. Do not copy and paste the code into the editor and try to compile it yourself! The forum software introduces garbage symbols that lead to compiler errors. I don't post the code myself. The forum software automatically extracts the source code from the compiled file for online display. So it is safe to download as it is impossible to manipulate the source code. This indicator does not work fully with ICMarkets due to their guaranteed volume policy that causes excessive flooding of the indicator's internal volume lists. Even though it is possible to filter this volume this still corrupts and excessively inflates the data file. It will work when the save is turned off and the hi-filter is set to a relatively low setting of 20 (million). In this case there is no backfill. There is no limit to the amount of data that is collected in the file. That means that the file may one day have the size of hundreds of megabytes. If it gets too big for the user it may just be deleted so the algorithm will then start a new file. The current location of the data file is: C:\users\yourusername\documents   Version 1.1 (28.5.2015) Save feature added Minor mistakes corrected Volume low-filter added Number of digits extended to two for CFDs  
Volume Log
free  02 May 2015
A volume log (v 1.01) that displays filtered bid and ask volumes. Price is expressed as distance from current bid/ask price in the Bid/Ask columns. Each entry is timestamped and expressed as relative to current time. Each change in volume is collected internally in realtime and then displayed in the specified interval according to its settings. For performance reasons the minimum display update frequency is 1 second. After a certain number of bars the oldest items are dropped off the list. This behaviour can be controlled with the "List Length: Bars" parameter. You can change the color of the text by typing the name of the color into the parameter box. Here is a list of valid colors: . Do not copy and paste the code into the editor and try to compile it yourself! The forum software introduces garbage symbols that lead to compiler errors. I don't post the code myself. The forum software automatically extracts the source code from the compiled file for online display. So it is safe to download. This indicator does not work with ICMarkets.   This is version 1.01 V1.01: Change the color of the text with the new "Text Color" parameter.    
VWAP for every bar
free  25 Apr 2015
This is the VWAP (version 1.1), or volume weighted average price for every individual bar. For timeframes shorter than daily it uses minute data up to the current second and then continues the calculation seamlessly with realtime tick volume for an accurate realtime VWAP display. For longer timeframes it uses 10 minute data, with only slight inaccuracies. DO NOT copy & paste and then try to compile the code yourself! The forum software introduces garbage symbols that I have no control over. I don't post the source code myself. The forum software extracts the source code from the uploaded file and what you see is the actual code that was included and compiled. So you can safely download. Sometimes there are periods in the chart that can't be properly displayed and are subsequently filtered. These periods appear as blank periods. On my charts for example this happens every day between 21:45 - 22:15 UTC. This only affects the historical VWAP. The realtime calculation usually works out fine because the indicator counts its own volume.  Note that if the indicator's values are off, all you have to do is right-click on the chart and select refresh. This should work out any problem during the first start up of the indicator. If that doesn't work, you may switch to another timeframe and then back to your original timeframe. Indicator Options Volume down & up color: This controls the coloring of the VWAP depending on the relation of the current volume to the previous volume. If the volume is up compared to the previous period's volume then the VWAP is colored the up color. If the volume is down it gets the down volume color. Here is a list of valid color names: You have to write their full name out. Coloring based on real volume: As mentioned the indicator counts its own volume. All it does is it increments a counter with every incoming tick. This results in a significant overhead of 20%-70% compared to the platforms reported tick volume for that period because the platform does not use true tick volume in its data collection. Rather it counts ticks that have a price difference to the previous tick and discards prices that have the same value. Therefore the platforms volume is really just price change event volume, or up and down tick volume. However, in my experience most of the time the relative volume differences are the same. On some occasions however this might still effect the coloring of the VWAPs. Turn this option off to use the platforms reported volume and to prevent any disruption due to the higher volume levels after indicator startup. Or turn it on to discover hidden high volume turns more effectively. Marker type: The VWAPs are displayed as ASCII or unicode symbols (dashes) that I copied from various sites. You can change their appearance by selecting marker 1 through 6. Let me know if you have problems with the symbols. Lookback: Included for performance reasons you can control how far back you want to display the VWAPs. On my platform it goes back only 7 days due to the lack of minute data. Therefore it won't display anything before that. You can safely choose a high value without harm though. There seems to be no performance hit, neither on historical download nor realtime calculation and display.   This is version 1.1 V1.01: Re-enabled the 1 Minute timeframe. This seems to work for scalpers. V1.02: New menu point. Changed the underlying coloring method. Various text edits on this page. V1.1: For longer timeframes than intraday 10 minute data is now used for a longer data plot into the past. This is automatic once the user selects a timeframe equal to or higher than daily. Examples:

Here you have the HL barchart, without the open and close dashes of the standard OHLC appearance, that are in my opinion arbitrary and therefore useless. You have to switch to line chart and change the "Bear Outline" color to the same as your background color of the underlying chart to make the price series disappear. Currently there is no other way to hide the price series. With the "Volume Bars?" parameter switched to "yes" it turns into the SierraChart style high-low volume barchart, where the width of the bars is determined by the underlying volume. This can be controlled with the "Minimum Bar Thickness" and the "Max. Bar Thickness (Volume Bars)" parameter. Note that these are NOT tick or volume charts where the volume would be the same for every bar.  I wanted to create something that resembles what is sometimes called "equivolume charts" as close as possible. It is self adjusting to current volume levels. This can be controlled with the "Lookback" parameter that controls the window width of the volume analysis. It also features a current price marker (see red triangle at the end of the priceseries), for those who don't like the distractiveness and the cluttering of the platforms own bid-ask lines. Right now all the colors can only be chosen by typing in the name of the color.   Changes: V1.01: Corrected a minor flaw in the algorithm V1.02: Removed unnessessary lines of code and further optimized logic. Removed redundant variable declarations. V1.03: Speed increase up to 25% by removing redundant operations. Changed the categorization process to exclude current forming bar. V1.04 Corrected a problem were some bars would be wrongly categorized and appear too thin in the Volume Barchart.
Fixed Offset Bands
free  19 Mar 2015
This is a band indicator based on various moving averages with its upper and lower band placed at a fixed distance expressed in pips. It does not compensate for trend strength or volatility. It works best on the temporary fair value as underlying data source.
