Indicador VPA

[JonaspPaulo]

Olá. Tenho dúvidas sobre o indicador de volume do VPA. Existe algum lugar que explique o indicador? Minha dúvida seria em relação às figuras que aparecem nas barras e a coloração de cada figura.

Hello JonaspPaulo,

Is the indicators name specifically VPA? If so that is not a indicator that comes with NinjaTrader normally so I don't have any information on it, if that is from a third party source you would have to review the information associated with it where you downloaded it.

Olá. Tenho dúvidas sobre o indicador de volume do VPA. Existe algum lugar que explique o indicador? Minha dúvida seria em relação às figuras que aparecem nas barras e a coloração de cada figura.

I am not using VPA, but AI is usually great analyzing the code:







The VPA (Volume Price Analysis) Indicator in NinjaTrader uses colors to visually differentiate between various price-volume action conditions and trends. Below is an explanation of the colors used and their meanings:

---

1. Bar Colors (Price Bars)

These colors indicate the current trend based on short-term, medium-term, and long-term slopes.

Lime Green	Strong uptrend (short, medium, and long-term trends are up)
Green	Medium and short-term uptrend, but long-term is down
Pale Green	Weak uptrend, only short-term is up while medium/long are down
Red	Strong downtrend (all trend slopes are down)
Orange	Weak downtrend, with mixed trend slopes
Yellow	Neutral or uncertain trend

---

2. Volume Bar Colors

The volume bars reflect buying or selling pressure:

Blue	Volume moving average (EMA)
Lime Green	Strong buying volume
Red	Strong selling volume
Yellow	Uncertain or mixed pressure

---

3. Special Conditions and Shapes

The indicator marks special price actions using colored shapes:

Upthrust Bar	Square	Red	Weakness, likely reversal
Confirmed Upthrust	Triangle Down	Red	Strong confirmation of weakness
Pseudo Upthrust	Square	Blue	Weaker form of upthrust
Reversal Likely Bar	Diamond	Blue	Price likely to reverse soon
Supply Test	Square	Deep Pink	Test to see if supply is present
Successful Supply Test	Triangle Up	Yellow	Strength confirmation
Strength in Downtrend	Square	Lime	Buying strength in a downtrend
Distribution Bar	Square	Blue	Smart money selling into strength
Effort to Rise	Diamond	Turquoise	Attempt to push price up
Effort to Fall	Diamond	Yellow	Attempt to push price down
Stopping Volume	Diamond	Lime	Potential end of bearishness
No Demand Bar	Square	Blue	Weak buying pressure
No Supply Bar	Diamond	Lime	Weak selling pressure

---

4. Banner Colors (Text Alerts)

The indicator displays alerts with colored banners for important signals:

Red	Weakness signal (e.g., Upthrust)
Blue	Reversal or Distribution warning
Lime	Strength signal (e.g., Supply test, Strength in Downtrend)
Yellow	Mixed or neutral alert

---

5. Background & Text Colors

• Band Area Color: Silver (Background shading)
• Text Color: White or Yellow (For indicator messages)

---

Summary

• Green/Lime shades = Strength (bullish)
• Red shades = Weakness (bearish)
• Blue shades = Warnings or potential reversals
• Yellow/Orange = Uncertainty or mixed signals
• Shapes (Square, Triangle, Diamond) highlight special price-volume patterns.

Hello MiCe1999,

I couldn't comment on AI generated code or responses, that response appears to be an imagination. The VPA is not something that comes with NinjaTrader so those instructions don't seem to be valid at all.

If you have a specific real indicator that you had a question about we may be able to assist.

Hello MiCe1999,

If you have a specific real indicator that you had a question about we may be able to assist.

Above is ChatGPT 4o code analysis of VPA indicator (https://ninjatraderecosystem.com/use...njatrader_jim/), not the information from AI training data.

"Yes, my description of what the colors mean in the PVA (Volume Price Analysis) indicator was based directly on the code you provided.

I analyzed the color definitions, conditions, and logic in your NinjaTrader script, particularly in the following sections:

• Bar Colors: Defined in the OnBarUpdate() function under BarBrush settings.
• Volume Bars: Defined under the AddPlot() function with Brushes.Blue, Brushes.LimeGreen, Brushes.Red, and Brushes.Yellow.
• Shapes & Markers: Found in the OnBarUpdate() function where specific conditions trigger different shapes (triangles, squares, diamonds) and colors.
• Banner Messages: Alerts and textual explanations using colored banners.

1. Bar Colors (Price Trend)

Defined in: OnBarUpdate() (Lines ~760-780)


The BarBrush is colored based on the trend slopes.

if (ColorBarToTrend) { if (ShortTermTrendSlope > 0 && MiddleTermTrendSlope > 0 && LongTermTrendSlope > 0) BarBrush = Brushes.Lime; // Strong uptrend (all slopes up) else if (ShortTermTrendSlope > 0 && MiddleTermTrendSlope > 0 && LongTermTrendSlope < 0) BarBrush = Brushes.Green; // Medium/short-term uptrend, but long-term down else if (ShortTermTrendSlope > 0 && MiddleTermTrendSlope < 0 && LongTermTrendSlope < 0) BarBrush = Brushes.PaleGreen; // Weak uptrend, medium/long-term down else if (ShortTermTrendSlope < 0 && MiddleTermTrendSlope < 0 && LongTermTrendSlope < 0) BarBrush = Brushes.Red; // Strong downtrend (all slopes down) else if (ShortTermTrendSlope < 0 && MiddleTermTrendSlope > 0 && LongTermTrendSlope > 0) BarBrush = Brushes.PaleGreen; // Mixed trend, slightly bullish else if (ShortTermTrendSlope < 0 && MiddleTermTrendSlope < 0 && LongTermTrendSlope > 0) BarBrush = Brushes.Orange; // Medium/short-term down, long-term up else BarBrush = Brushes.Yellow; // Neutral or uncertain trend }
Summary of Bar Colors

Lime	Strong uptrend (all slopes up)	if (ShortTermTrendSlope > 0 && MiddleTermTrendSlope > 0 && LongTermTrendSlope > 0)
Green	Medium/short-term up, long-term down	else if (ShortTermTrendSlope > 0 && MiddleTermTrendSlope > 0 && LongTermTrendSlope < 0)
Pale Green	Weak uptrend	else if (ShortTermTrendSlope > 0 && MiddleTermTrendSlope < 0 && LongTermTrendSlope < 0)
Red	Strong downtrend (all slopes down)	else if (ShortTermTrendSlope < 0 && MiddleTermTrendSlope < 0 && LongTermTrendSlope < 0)
Orange	Medium/short-term down, long-term up	else if (ShortTermTrendSlope < 0 && MiddleTermTrendSlope < 0 && LongTermTrendSlope > 0)
Yellow	Neutral trend	else

if (upThrustConditionThree) Weak[0] = (Volume[0]); // **Red** → Very strong selling pressure else if (upThrustConditionTwo) Weak[0] = (Volume[0]); // **Red** → Confirmed selling weakness else if (isUpThrustBar[0]) Weak[0] = (Volume[0]); // **Red** → Upthrust (bearish) else if (strenghtInDownTrend) Strong[0] = (Volume[0]); // **Lime Green** → Strength in downtrend else if (strenghtInDownTrend0) Strong[0] = (Volume[0]); // **Lime Green** → Strength in downtrend else if (strenghtInDownTrend1) Strong[0] = (Volume[0]); // **Lime Green** → Strength in downtrend else if (strenghtInDownTrend2) Strong[0] = (Volume[0]); // **Lime Green** → Strength in downtrend else StrongWeak[0] = (Volume[0]); // **Yellow** → Unclear signal
Summary of Volume Bar Colors

Lime Green	Strength in downtrend (buying pressure)	Strong[0] = (Volume[0]);
Red	Weakness due to upthrust or selling	Weak[0] = (Volume[0]);
Yellow	Mixed signal (buy/sell unclear)	StrongWeak[0] = (Volume[0]);

if (isUpThrustBar[0] && !isNewConfirmedUpThrustBar[0]) Draw.Square(this, "MySquare" + CurrentBar, true, 0, High[0] + 2 * TickSize, Brushes.Red); // Upthrust (Weakness) if (reversalLikelyBar) Draw.Diamond(this, "MyDiamond" + CurrentBar, true, 0, High[0] + 2 * TickSize, Brushes.Blue); // Reversal likely if (isNewConfirmedUpThrustBar[0]) Draw.TriangleDown(this, "MyTriangleDown" + CurrentBar, true, 0, High[0] + 2 * TickSize, Brushes.Red); // Confirmed upthrust if (strenghtInDownTrend) Draw.Square(this, "MySquare" + CurrentBar, true, 0, Low[0] - 2 * TickSize, Brushes.Lime); // Strength in downtrend if (successfulSupplyTestBar) Draw.TriangleUp(this, "MyTriangleUp" + CurrentBar, true, 0, Low[0] - 2 * TickSize, Brushes.Yellow); // Successful supply test if (stopVolBar) Draw.Diamond(this, "MyDiamond" + CurrentBar, true, 0, Low[0] - 2 * TickSize, Brushes.Lime); // Stopping volume
Summary of Shapes & Colors

Square	Red	Upthrust (weakness)	Draw.Square(..., Brushes.Red);
Triangle Down	Red	Confirmed upthrust	Draw.TriangleDown(..., Brushes.Red);

Hello MiCe1999,

The file you linked to was created by a user so the only information that we have on that would be what the user put in the description. That is a third party item so you would have to investigate the code if you wanted to learn more about how that item works.

Understood, makes sense. Thanks for following up.
