I don't understand what the advantage would be of a 30 moving average vs the average of ALL the bars, except for days like yesterday and today where the volume is much lower than average.

In statistics, the larger the data set, the more reliably you can fish out extremes.

Using the average of all the bars, indeed, makes the line flat.

I have adapted the VSA code to handle all three volume average options. I will take a little bit of time over the weekend to see whether my two options make sense.

Good question. What's the advantage? Probably the original programming authors know. However, I just thought it would be good to be consistant with the VPA code, since this discussion is about VSA. You code doesn't display like the TradeGuider's screen shot that you posted. Maybe the advantage is to get it to look more like your TradeGuider screen shot.

I have implemented the EMA, Day/Night, and Hourly averages in the VSA7 script.

However, I have troubles sharing it. There are too many chars for this forum.
"The text that you have entered is too long (47247 characters). Please shorten it to 30000 characters long."

So, I will have to split it up.

VSA7 UPPER part 1

 
Code
declare upper;
declare real_size;

# This is a conversion of the NinjaTrader VPA indicator.  ToS does not support directional
# triangles and diamonds, so there are some differences.  The triangles are left as is, just
# not pointing a specific direction.  The diamonds have been replaced with circles.

# C_RP Original notes by cbritton are above. Changes made after 20100722 by Richard Paske are marked below by the C_RP comment tag. A few bugs were fixed. More significantly, the color scheme for symbols was changed radically in an attempt to map directional strength to hue based on the ROYGBIV color spectrum. In addition, a symbol's shape and its vertical position above or below a candle now imparts added meaning to it. In general, the strength of a symbol is assigned by its color and shape in that order. In certain circumstances a symbol's vertical offset from its candle's top or bottom strengthens the symbol's meaning. The symbol strength  hierarchy is defined as follows:

# 1. Color: Symbols below candles are assigned strength from weakest to strongest in this order: white (or grey), cyan (blue/green), green. A red symbol under a candle indicates the failure of the symbol attached below the candle immediately preceding it.
# Symbols above candles are assigned strength from weakest to strongest in this order: yellow, orange, red. A green symbol above a candle indicates the failure of a symbol attached above the candle immediately preceding it. A magenta (pinkish purple) square above a candle is a special case indicating Distribution. Another special case for testing purposes as of 20100830 is a white triangle high above a candle indicating a Gravestone Doji.
# Symbols drawn on the middle of a candle are of two types with one variation. A green circle indicates Effort to Move Up on up bars. A magenta (pinkish purple) circle indicates Effort to Move Down on down bars except for red down bars on which magenta displays poorly. In order to be seen easily, yellow circles indicate Effort to Move Down on red down bars.

# 2. Shape: A symbol of a given color is assigned increasing strength according to this hierarchy (from low to high): circle, square, triangle, downward or upward arrow. In certain circumstances two symbols of the same shape and color will be stacked vertically, adding strength through the combined symbols. Occasionally, two different symbols will be stacked vertically because that candle satisfies the criteria for two indications.

# Listed below are the symbols and their meanings. The original symbol chart can be found at the end of this study.

# ___Symbols Below Candles___
# White Square - Test for Supply
# Cyan Circle - No Supply
# Cyan Triangle - Successful Test for Supply
# 2 Cyan Triangles - Successful Test for Supply 2

# Grey Square - Test for Supply in Uptrend

# Green Circle - Stopping Volume

# Cyan Square - Strength in Downtrend
# Green Square - Strength in Downtrend 1
# Green Triangle - Strength in Downtrend 2
# Green UpArrow - Strength Confirmation Bar
# 2 Green UpArrows - Strength Confirmation Bar with High Close
# Red Square - Failed Strength Signal


# ___Symbols in the Middle of Candles___
# Green Circle - Effort to Move Up
# Magenta Circle - Effort to Move Down
# Yellow Circle - Effort to Move Down on Red Down Candles

# ___Symbols Above Candles___
# White Triangle - Gravestone Doji (included as an experiment as of 20100830 to test its usability in the UpThrust category)
# Yellow Triangle - Weakness

# Orange Circle - No Demand
# Orange Square - PseudoUpThrust
# Orange Triangle - PseudoUpThrust Confirmation

# Red Square - UpThrust
# Red Triangle - Confirmed UpThrust Condition 1
# Red DownArrow - Confirmed UpThrust Condition 2 or 3
# Green Square - Failed UpThrust or PseudoUpThrust Confirmation

# Red Circle - Reversal Likely
# Magenta Square - Distribution
# Magenta Triangle - Two or Three Period UpThrust

VSA7 lower (on_volume) study. This is a separate study from the one above !

If you select a volume average type in the upper study, you should also select the same volume average type in the lower study.

I have tried to make one study out of it, but that didn't work.

I think this script shows that the EMA30 looks a bit odd when you use overnight sessions.
I think the day/night split makes more sense, even though it was not implemented by the TradeGuider people.

The EMA30 and day/night split looks very similar when you only use regular trading hours with e.g. the SPY.

marcovth,

Nice work. One possibility for your code is to place it into a text file and upload it as an attachment. Actually, it's best that you make them attachments. I get a lot of errors when cutting and pasting. Some of the errors are from repeditive definitions of the same variable. There's a lot of code for various hours of the day. How does that help with a trading decision?

The number of NYSE stocks that have risen in price compared to their close on the previous trading day are called "Advancing Issues". The number of NYSE stocks that have fallen in price compared to their close on the previous trading day are called "Declining Issues".

Of course, the stocks (issues) are being traded in volume, "Advancing Volume" and "Declining Volume".

I think we can use that volume to approximate the buying/selling pressure when trading e.g. the ES and SPY.

This could give a new level of understanding to VSA.

I made the following code.
- In green, you see the number of Advancing Volume vs yesterdays close.
- In red, you see the number of Declining Volume vs yesterdays close.
- A bar greater than 0, shows that the resp. volume has increased vs yesterday.
- A bar less than 0, shows that the resp. volume has decreased vs yesterday.

It seems the numbers for overnight trading get's accumulated and is shown in the 9:30 bar, therefore I skip that bar to avoid a giant spike.

Take a look at it for yourself, and see if it makes any sense when explaining VSA signals.
I only played with it for the day, so I don't have trading rules yet.

rec SumTVol = if MarketsHours then SumTVol[1] + (TVol - TVOL[1]) else SumTVol[1];

def AvgTVol = SumTVol / nBarsTVOL;

rec UVOLspike = ((UVOL - UVOL[1]) / AvgTVol);
rec DVOLspike = ((DVOL - DVOL[1]) / AvgTVol);

You're very creative in your approach to VSA. You must have studied it thoroughly with years of experience using it.

Attached is a test code for reversals; however, I don't think it turned out very well. Also, I'm using my own bar colors.

Hi SJ! What is the meaning of the colours?
tnx

I think a better question would be "How do the colors help in trading?" No one seems to know how they help; whether they're my colors or some one else's.
