Peak Volume Price

Recommended Posts

I tried to add the PVP code (OEC EL) that POPSTOCKS kindly posted on TL, however it failed to compile.

 

I tinkered with the 'Counters' as this was where the error message was pointing to.

 

I can now get it to run, but it appears to be giving me the PVP of each bar.

 

When i compare it to my Volume @ price histogram it returns a differnet value.

 

Is this because it is giving me the Peak volume Price from when the indicator is added / enabled, and is only of use in real-time?

 

Any help would be greatly appreciated.

 

Vars: Counter(0),
Op(0), 
Ct(0), 
hh(0), 
f(0),
mintick(0);

Array: v[800](0), p[800](0);

mintick=minmove/pricescale;

If 1 = 1 then Ct =1+Ct;
If Date > Date[1] or Ct = 1 then begin
Op = Open-100;

For Counter = 1 to 800
begin
p[counter] = 0;
v[counter] = 0;
End;

End;

For Counter = 1 to 800
begin
p[counter] = (counter*mintick)+Op;

If Close = p[counter] then v[counter]= volume+v[counter];

End;

hh = highestarray(v,800);

if hh> hh[1] then f = close;

Plot1(f);

please wrap the code with code tag. That's the # key at the top of the message window.

Unwrapped codes are difficult to read (and debug).

Thanks for the expediant reply Tams.

 

I see what you mean, I've checked back and all POPSTOCKS PVP codes, and other TL users veriants use it, but what it does i have no idea.

 

I'm learning EL as i go, and my only programing knowledge is BASIC from when i was a kid (20 years ago). I looks like a loop of some kind.

 

I've removed the line you hightlighted,

 

the PVP line follows the current price bar, and is not giving the correct signal.

 

I have a volume histogram on OEC, but this is set to the day volume and is not user adjustable (from OEC tech support)

 

So the VOL@price histogram give a rough PVP, but isnt session accurate a volume traded befor the cash open is also diplayed. Besides i find it distracting having to keep update a PVP line manually on my chart.

 

Thanks VT

Further to my PVP Problems, I tried out the another code from the TL site..

vars:         MyVolume(0),
	PriceDiff(0),
	StartPrice(0),
	PVPPrice(0),
	PVPVolume(0),
	V2VolLevel(0);	

Array:
	PVPVolArray[10000] (0);

MyVolume = Volume;

if date > date[1] then begin
	StartPrice = AvgPrice;
	For Value1 = 0 to 10000 Begin
		PVPVolArray[Value1] = 0;
	End;
	PVPVolArray[5000] = MyVolume;
	PVPPrice = AvgPrice;
	PVPVolume = MyVolume;
end;

If date = date[1] And StartPrice > 0 Then Begin
	Value2 = AvgPrice - StartPrice;
	V2VolLevel = 5000+(Value2*(1/(minmove/pricescale)));
	PVPVolArray[V2VolLevel] = PVPVolArray[V2VolLevel] + MyVolume;

	If PVPVolArray[V2VolLevel] > PVPVolume Then Begin
		PVPVolume = PVPVolArray[V2VolLevel];
		PriceDiff = 5000-V2VolLevel;
		PVPPrice = StartPrice - (PriceDiff*(minmove/pricescale));
	End;

End;

Plot1(PVPPrice, "PVP");
Plot2(PVPVolume, "PVPVolume"); 

 

I've turned off the tick-by tick update option, else the pvp line seems to follow the last price.

 

My question is, is this reliable? The reason i question it is that my volume histogram shows the price with the most volume traded at different level. Am i missing somthing here? i've Demo traded using it before running it live, and some signals using the code seem to be correct, then at other times it appears my histogram peak volume is the correct one!

you should always provide a link to your source...

1. give the original author credit

2. so that ppl can understand the background... instead of starting from nowhere.

That looked mightily familiar for some reason. Mind you I wrote a big chunk of the PvP indicator for DBtina... actually I took a big chunk and made a small perfectly formed chunk :)

 

This works for me without ADE. It averages the data across the bar so you do not update it every bar (like Ensign and Jerry's original stuff) it does a couple of other funky things too like variable number of days, old pvp. It has some comments but was kind of 'lazy' code maybe that will help you get a handle

//
//	PvP Averaged across bar. Set update at end of bar true.
//	See PvP Tick Precise version also
//

Input:
	PlotOldPvP (false),
	NumberofDays (1);

vars:
	n(0),m(0),
	StartPrice(0),						// Price corresponding to first element of  array
	PVPPrice(0),
	PVPPrice1(0),
	PVPPeakVolume(0),
	PVPIndex(0),							//Index of the peak (highest) volume array element
	PVPArraySize(3000),						//Set to Array Size
	PVPArrayMid(1500);						//Set to Array Mid Point
Array:
	PVPVolArray[3000] (0);					//Make sure this matches Array Size


if BarNumber = 1 then n = NumberofDays - 1;			//Make sure to reset on first bar
if (date > date[1]) or BarNumber =	1  then begin			//initialise
	n = n + 1;
	if n = NumberofDays then		
	begin	

		For Value1 = 0 to PVPArraySize Begin
			PVPVolArray[Value1] = 0;
		End;
		StartPrice = l;
		PVPPrice1 = PVPPrice;
		PVPPrice = StartPrice;
		PVPPeakVolume = 0;
		PVPIndex = PVPArrayMid;
		//PVPVolArray[PVPIndex] = Volume;
		n = 0;
	end;
end; 

Value2 = l - StartPrice;				//price in relation to starting price
value2 = value2 * (1/(MinMove/PriceScale));		
Value2 = PVPArrayMid+Value2;
value3 = (h-l) * (1/(MinMove/PriceScale));       // number of ticks l -> h				
Value1 = Round(Value2,0);				//shouldnt be needed as not adding to average price 
for m = Value1 to value1 + value3
begin
	PVPVolArray[m] = PVPVolArray[m] + Volume / (value3+1);	// +1 as as zero ticks should be vol/1 one tick vol/2 etc.
	If PVPVolArray[m] > PVPPeakVolume Then begin		// new peak volume? save it
		PVPIndex = m;
		PVPPeakVolume = PVPVolArray[m];
		PVPPrice = StartPrice - ((PVPArrayMid - m)*minmove/PriceScale );
	end;
end;

Plot1(PVPPrice, "PVPavg");
if (PVPPrice1 > 0 and PlotOldPvP) then Plot2 (PVPPrice1, "PVP Yesterday");

Can somebody help me .....

 

This indicator was working just fine for weeks on my charts. All of the sudden it won't work when I use it on my AAPL chart. It still works fine on the SPY. Anyone got an idea how to fix this?

    • Date: 28th March 2024. The US Dollar Strengthens As Economists Believe The ECB Will Struggle To “Hold”. Early this morning, the Fed Governor advised “there is no rush to cut rates” and “the data within the upcoming months” will be vital. The US Dollar Index rises to a 1-month high. The value of the USD will largely be based on today’s data on economic growth, consumer sentiment and pending home sales. Dollar and index traders are closely monitoring tomorrow’s Core PCE Price Index which analysts expect will read 0.3%. A higher inflation reading can potentially pressure stocks and support the Dollar. Strong declines in NVIDIA and Netflix stocks pressured the NASDAQ on Wednesday. Though, buyers entered late in the session to boost the overall price. EURUSD The latest comments from members of the Federal Reserve are supporting the US Dollar. The forward guidance between members of the Federal Reserve is mainly not aligned. The Chairman advises the Fed does not need much more proof for the regulator to feel comfortable reducing rates. Whereas the Fed Governor, Mr Waller, advises there is no rush, and he wants to see a few months of data before determining the next move. Therefore, the upcoming inflation and employment data will remain vital and could even push back rate hikes further. According to economists, the Federal Reserve will cut the interest rate on 3 occasions this year, but the timing of the first cut is less certain and may change depending on upcoming data. A positive factor for traders is that EURUSD exchange is not witnessing conflicting currencies. The US Dollar is trading 0.12% higher while the Euro is declining against most currencies. The Euro is trading 0.06% lower against the Pound and the Canadian Dollar and 0.16% lower against the Japanese Yen. Yesterday, the head of the Bank of Italy, Mr Cipollone, said that the authorities were confident that inflation would return to the target of 2.0% by mid–2025. He also supports the lower of interest rate and will use this as a basis for adjusting monetary policy. The Euro is generally under pressure as investors believe the European Central Bank will struggle to avoid cuts if the Fed decide to delay their adjustments. The US Dollar will be influenced by four major economic data releases. The US Final GDP, Weekly Unemployment Claims, Pending Home Sales and Consumer Sentiment Index. If these read higher than expectations with the weekly unemployment claims dropping, the US Dollar is likely to witness further support. However, investors should note the main release will be tomorrow’s Core PCE Price Index. Traders are expecting no major news for Europe and volatility levels may fall tomorrow as European markets are closed for Easter. Technical analysis currently points towards a continued downward trend. The price is trading below the neutral on the RSI and below the 75-Bar EMA. However, investors should note this will also be dependent on upcoming US data. USA100 The price of the USA100 was under pressure throughout the whole US session but was saved by an increased volume of buyers late in the session. However, a positive point is the components held onto their value. Even though the index fell in value, only 28% of the components declined. Investors will now turn their attention towards tomorrow’s PCE Price Index and the upcoming earnings season which will start in mid-April. The price is now trading slightly above the Moving Averages but slightly below the 50.00 on the RSI. Therefore, technical analysis remains at the “neutral” level and continues to indicate a larger price range. If today’s economic data is positive the stock market can witness confidence and support as this continues to indicate a soft landing. Though, if the data is too strong, it could also trigger a hawkish Fed which is known to be negative for the USA100. Always trade with strict risk management.
