Volume Breakdown (VB)

Volume Breakdown Indicator requires the Volume Analysis Package.

The Volume Breakdown is a powerful and flexible indicator used to gauge buying and selling pressure. It looks inside each bar, breaking down and classifying each tick and then accumulating the results (accumulation is optional), and further giving the user a variety of statistical measures (including all built-in technical indicators) to apply the these results. The most common use of the VB indicator is to calculate the delta (difference between the buy (ask-traded) and sell (bid-traded) volume) of each bar. Positive deltas signify more buying pressure, while negative deltas signify more selling pressure. The magnitude of the delta determines the strength of that pressure. Expect to see positive deltas during uptrends and negative deltas during downtrends, but look for delta turning negative at highs, or turning positive at lows...a sign of possible market turns and good entry/exit points.

With the VB indicator, the Delta can be computed, accumulated, and run through a variety of statistical/indicator computations.

The VB indicator is unique in that it loads tick data (when initially computing) regardless of the timeframe of the chart, in order to breakdown the volume of each trade, and calculates on each tick. While it may take a few moments to initially add VB to a chart, or load a chart which involves VB, the VB indicator is designed to calculate very efficiently on a tick-by-tick basis, regardless of the combination of settings selected.

Formula

The Volume Breakdown indicator uses 4 types of different inputs

Input #1 - Breakdown method : volume can be broken down based on two main methods:

  • Ask Traded vs Bid Trade Volume - Volume that trades at the ask price is considered buy volume, while volume that trades at the bid is considered sell volume

  • Up Tick vs Down Tick Volume - Volume that trades on or subsequent to an up tick is considered buy volume, while volume that trades at or subsequent to a down tick is considered sell volume.

Note : Three other advanced breakdown options (Bid Delta, Ask Delta, and Bid Ask Delta) are designed to help traders identify the level of refreshed bids and offers that are occurring. Check the “Related” Tab for more information on these options.

Input #2 - Output Result type -This list dictates what the VB indicator will compute (before applying any accumulation or statistics to it). Result options include:

  • Delta (Buy - Sell Vol) - difference between the buy volume and the sell volume.

  • Delta Bars - same as "Delta", except drawn in a candle bar format.

  • Buy Volume - Volume that traded at or above the ask.

  • Sell Volume - Volume that traded at or below the bid.

  • Sell Volume (Negative) - Volume that traded at or below the bid, expressed as a negative value. This option is there so that Buy Volume and Sell Volume histograms may be added to the same pane, but drawn on different sides of the zero line.

  • Total Volume - Total volume traded.

  • Total Trades/Ticks - Total number of trades or ticks.

  • Buy Volume % - Percent of volume within each bar which was classified as Buy Volume.

  • VWAP (Bar) - Volume weighted average price of each bar. Each tick is weighted by it's volume to produce a weighted average price of all ticks within each bar.

  • Big Volume % - Percent of volume within each bar which was classified as "Big Volume". "Big Volume" is defined as any trade with a size greater than a size specified to the right of the "Consider Only Trades With Volume" checkbox. That Volume Box will be editable whenever "Big Volume %" or "Big Trade %" results are selected.

  • Big Trade % - Percent of Trades within each bar which was classified as "Big Volume". This result simply deals with the number of trades, as opposed to the size of those trades.

  • Average Size - Average size of the trades which occurred within any given bar.

  • Max Delta - The maximum delta value achieved within each bar. This is equivalent to the high seen for each deltabar.

  • Min Delta - The minimum delta value achieved within each bar. This is equivalent to the low seen for each deltabar.

  • Delta Momentum - Delta Momentum essentially sums up the delta values while the per bar delta remains on the same side of the zero line. When delta turns from positive to negative, the result will reset to that negative values, and the result will continue to accumulate while the deltas remain negative. When delta becomes positive, the result will reset back to that positive value, and accumulate from there while delta remains positive.

  • Delta Mom Count - Delta Mom Count works in the same way, except it simply counts how many bars delta has remained positive or negative consecutively. A value of -5 means we've had 5 consecutive negative delta bars.

  • Matching Volume - High - Amount of volume that traded on both sides (buy and sell volume) at the high of the bar. In general, at the high of the bar, most (if not all) volume will trade at the ask (buy volume).

  • Matching Volume - Low - Amount of volume that traded on both sides (buy and sell volume) at the low of the bar. In general, at the low of the bar, most (if not all) volume will trade at the bid (sell volume).

  • Avg Buy Size - Average size of all trades that came in on the buy/ask side.

  • Avg Sell Size - Average size of all trades that came in on the sell/bid side.

  • VWAP(Day) Volume Weighted Average Price of all tick accumulated throughout each session.

  • VWAP(All) - Volume Weighted Average Price of all tick accumulated throughout the entire view period of the chart.

  • Delta Finish - This is the pullback of delta from it's last high or low. If Delta last bounced off it's high before completing bar, the finish will be negative (or zero). If Delta last bounced off it's low before completing bar, the finish will be positive (or zero).

  • Time in Bar (Secs) - Amount of time, in seconds, spent in each bar. Especially useful for tick-based periodicities like tickbars, volume bars, range bars, PNF, Renko, etc.

  • Logarithmic Pressure Ratio - LOGe (Buy Volume / Sell Volume). Commonly a moving average is applied to this result.

  • Money Flow (Delta x Close) - Delta of the bar multiplied by the closing price of the bar.

  • Buy Trades/Ticks - Number of trades that occurred at or above the ask.

  • Sell Trades/Ticks - Number of trades that occurred at or below the bid.

  • Buy Dollar Value - A summation of the Close x Volume of each buy tick within the bar.

  • Sell Dollar Value - A summation of the Close x Volume of each sell tick within the bar.

  • Delta Change - Change in the delta from current bar. In other words, current bars delta minus previous bars delta. This is a good indication of the direction of delta.

  • Time of High price - Returns the time in a hh.mmss format the time of the High of the Bar

  • Time of Low price - Returns the time in a hh.mmss format  the time of the Low of the Bar

  • Big Bar Delta - This result accumulates the buying volume and selling volume of each 1 second period. It also accepts a volume filter which is placed in the "Consider Trades With Volume" field. If the buy volume of any given second exceeds the volume filter supplied, it is accumulated into the buying volume of the bar. If the sell volume of any second exceeds the filter, it is accumulated into the sell volume of the bar. The result for each bar is the accumulated buy volume minus the accumulated sell volume. This result essentially applies a filter, not on every trade, but on an accumulation of the trades within each 1 second period.

  • Bid Price Changes - This result counts how many times the bid price changed within each bar.

  • Delta Since High also referred as "COT High"- This result gives the delta since a new high of the price bar was achieved. Any time the price bar makes a new high, the delta resets to zero and builds from there.

  • Delta Since Low also referred as "COT Low"- This result gives the delta since a new low of the price bar was achieved. Any time the price bar makes a new low, the delta resets to zero and builds from there.

  • Delta Finish on Price also referred as "COT High/Low"- Any time the price bar makes a new low or a new high, the delta resets to zero and builds from there.

  • Volume Since High - This result returns the volume accumulated delta since a new high of the price bar was achieved. Any time the price bar makes a new high, the value resets to zero and builds from there.

  • Volume Since Low - This result returns the volume accumulated delta since a new low of the price bar was achieved. Any time the price bar makes a new low, the value resets to zero and builds from there.

  • Delta Per Since High - Delta % since High is based on the ratio between the "COT High" and the "Volume since High". Any time the price bar makes a new high, the value resets to zero and builds from there.

  • Delta Per Since Low - Delta % since Low is based on the ratio between the "COT Low" and the "Volume since Low". Any time the price bar makes a new low, the value resets to zero and builds from there.

  • Tick Frequency Rating (Live) - The "Tick Frequency Rating" option gives the user an indication of the frequency of trades in combination with tick direction (buying or selling). This rating will plot on a scale from 1 to 100+ (or -1 to -100+). A value of 1 signifies that the tick came in over 5 seconds from the previous tick. A value of 100 signifies that a tick came in right on top of the previous tick (essentially at the same millisecond). Values beyond 100 signify that multiple ticks continued to come in on top of one another. Values in between 0 and 100 are plotted with a reverse logarithmic scale. In essence, the higher the values, the faster the frequency of ticks. In addition, these values are plotted as positive values on buy ticks are up ticks and as negative values on sell ticks or down ticks (depending on how VB is setup). This result only works realtime, and therefore will begin forming from the time the chart containing it is opened, or from the time it's added to a chart. It also works best in on 1 tick charts. When viewed on other periodicities, it will sum the values of all ticks within the bar.

  • Ask Size (Live Only) - Plots the ask size at the time of each tick or trade. These values only plot live (the VB will be blank when initially opening the chart and build from there). The ask size plots as a positive value.

  • Bid Size (Neg) (Live Only) - Plots the bid size at the time of each tick or trade. These values only plot live (the VB will be blank when initially opening the chart and build from there). The bid size plots as a negative value, and plots nicely in a pane along w/ Ask Size.

  • Max Ask Size and Max Bid Size (Neg) (Live Only) - These results will get the maximum bid or ask size achieved within each bar. These options can be especially useful for an Auction (or 1 tick range) periodicity in which all ask trading occurred at the upper price and all bid trading occurred at the lower price. The Max Bid Size is presented as a negative number so it can be combined within the same pane with the positive Max Ask Size.

Important :The "Live only" results require a live data feed environment. When a chart is initially opened, there will be no historical data for these results, ie the data will form in the chart as soon as a live stream data is being received

Input #3 : Modification of the raw result values through one of the following methods

  • Normalize - An option was added to the Volume Breakdown indicator to allow the user to "Normalize" the result. When the "Normalize" checkbox is checked, the VB Result (such as Delta) is divided by the volume and then multiplied by 100, to give in effect a positive or negative percent of total volume. For instance, a normalized delta of 34 would mean that the delta was positive, and 34% of the total volume. A result of -100 would mean that all the volume traded in that bar was sell/bid volume (negative).

  • Accumulate/Avg/Max/Min -The Accumulate option allows the user to accumulate the values computed from the Result choice throughout the day (or throughout the entire chart). If a "x Minutes/Day/Week/Month/Quarter/year" period is selected, the accumulation will begin fresh each "x Minutes/Day/Week/Month/Quarter/Year", and accumulate throughout the selected period. If "All" is chosen, the accumulation will start at the begin of the chart and continue throughout the chart. In addition to "Accumulate", options are also available to compute the Average, Maximum, or Minimum value of the selected period. It is also possible to reset the calculation at the start of any custom period by using the VB indicator in conjunction with the Boundaries RTX indicator.

  • Max Accum / Min Accum - The "Max Accumulation" (resp. "Min. Accumulation") option will return the highest (resp. lowest) accumulation value experienced since the start of the selected period.

  • Statistic - A Statistic (or indicator) calculation can also be applied to the Result. Choices include:
    • None - No statistic is applied. Just use the raw Result computed above.
    • Average - Average the values using the Period specified to the right.
    • Sum - Sum the values over the period specified to the right.
    • Maximum - Find the Maximum value over last n bars (n = Period).
    • Minimum- Find the Minimum value over last n bars (n = Period).
    • Avg (Least Square) - Performs a least square average using the Period specified.
    • Indicator - When this option is chosen, the user is then presented with a list of technical indicators from which to choose (all built-in indicators that I/RT offers, including any custom indicator). Select the desired indicator and then click the "Setup" button just to the right to specify the indicator preferences. This indicator will be applied to the Result to compute the final values.
    • Speed (Per Second) - divides the "result" by the number of seconds in the bar.
    • Speed (Per Tick) - divides the "result" by the number of ticks in the bar.
    • Speed (Per Unit Volume) - divides the "result" by the volume of the bar.
    • Tick Momentum (T/t) - multiplies the "result" by the number of ticks in the bar, then divides by the time (in seconds) of the bar.
    • Volume Momentum (V/t) - multiplies the "result" by the volume of the bar, then divides by the time (in seconds) of the bar.

 

Input #4 : Filtering of the raw data source upon the individual trade size information

  • Consider Only Trades with Volume - This option gives the user the ability to apply a filter to the trades considered in the calculation. The user can choose to consider only trades > than a given size, < than a given size, or = to a given size

Finally, the "Draw As" menu offers different style option to draw the indicator in the chart.

Note : Very often, Volume breakdown information will be used inside custom indicators written in the RTL language thanks to the VB RTL token
