PRV -- Pro Rated Volume

 

For the volume hawks!

 

This indicator projects the volume at the end of the bar.

It calculates the PRV based on the current trade pace,

and the time remaining in the bar.

 

This information is useful to spot turning points

ie. whether the money is drying up... or flooding in.

 

This indicator is usable on minute charts only.

 

Instructions:

Set the volume to display as a thick histogram

and the PRV to display either as a thin histogram, or as a thick point.

Does anyone know how I can code Easylanguage for TS2000i to take the word "ComputerDateTime" from the code below with an alternative ? I have tried the word "CurrentTime" but it is not working quite the way it should do. The rest works fine and it is only this that is an issue.

 

 

Paul

 

if date = date[1] then

begin

CurrentTimeInSecs = ( ComputerDateTime - DateToJulian( Date ) ) * 86400 ;

TotSecondsDiff = CurrentTimeInSecs - CurrentTimeInSecs[1] ;

end;

here's the difference between the two keywords

 

 

The indicator needs to find out the Current Time In Seconds, the currenttime keyword can only supply the time in minutes.

 

 

 

 

ComputerDateTime

 

Returns a double-precision decimal DateTime value indicating the computer's current date and time.

 

The integer portion of the DateTime value indicates the number of days that have elapsed since January 1st, 1900,

and the fractional portion of the DateTime value indicates the fraction of the day that has passed since midnight.

 

Usage

 

ComputerDateTime

 

Example

 

ComputerDateTime will return a value of 39448.25000000 for 6:00 AM on January 1st, 2008

 

CurrentTime

 

Returns a numerical value, indicating the computer's current time.

The time is indicated in the 24-hour HHmm format, where 1300 = 1:00 PM.

 

Usage

 

CurrentTime

 

Examples

 

CurrentTime will return a value of 1015 for 10:15 AM

 

CurrentTime will return a value of 1545 for 3:45 PM

when i try to apply it to a chart it says floating point invalid calculation.

 

if you say it does not work, it can mean a lot of things.

I can't really help you when you are providing so little information...

 

what instrument are you applying the indicator to?

what is the chart resolution?

what is the error message? I cannot read your mind. please copy and paste the complete message here. (or make a screen shot).

Tams,

 

I find it quite fascinating that when you post a useful volume indicator on here the

"volume hawks" give it virtually no attention whatsoever . . .

 

Perhaps next time you should post some vague, wishy-washy, and totally subjective claptrap about volume spread analysis and what a 'big' bar means? Your post might get some more attention that way.

 

Anyway, thanks for the code!

The volume hawks are not saying much

because they have already got this indicator years ago.

Pro-Rated volume will never work on forex symbols because forex symbols don't report volume.

 

prv = (ticks/TotSecondsDiff) * 60 * barinterval; // this line triggers the FP Error because the value of ticks is zero.

If you're wanting to trade forex with volume as part of your strategy, you can always apply the indicator to the relevant fx futures contract, which will have volume.

Thanks, that's an excellent solution.

 

Forex doesn't interest me. I solve coding puzzles for their intrinsic value and there's still a lot I can learn from this one. Danhoyda hasn't provided enough details to make sense of it.

You're welcome. I agree it's a great indicator. Thank you Tams ....TXUK's ......and any other's involved that I've missed.

 

I'm curious what you changed???

 

pardon me I got it to work thanks for the help I changed something on the original code and thats why it didnt work. I changed it back and now it is.

 

Thanks.

 

Love the indicator.

I LOVE this indicator. Thank you very much for this. Could someone explain to clearly what exactly it is doing. My code understanding is very limited. Any help would be appreciated.

 

Thanks!

PRV estimates total volume (of a completed bar), while the volume is still incomplete and developing.

 

The version in this thread extrapolates the rate of developing volume (i.e. it pro-rates the volume) based on the assumption it will remain steady until the bar completes. This is a beginning point from which to begin searching for formulas that can distinguish viable signals. I have extensively developed skills for cataloging data such as this and performing any analysis imaginable. Just so you know in case anyone has an idea worth exploring and needs help implementing it. I don't have anything forsale and never will. I abhor that category of failed traders who fleece sheep to cover their trading losses.

Ha! And then there's that category who fleece sheep but don't have any trading losses to cover because they don't actually trade . . . :)

 

OneSmith has provided me with valuable coding assistance recently and didn't attempt to sell me anything, so I'll happily second his statement above and recommend seeking help from him with coding.

      Hello traders,
      I am interested in order flow trading and I will post some trades and predictions, some articles and ideology of a bit different understanding how price moves and why. May be this forum will be the right place. So, for the start I have  couple of charts of recent trade on oil. Also I did some comparison of two different software. Would be great to meet some traders who use order flow too. Lets see. I have a lots ideas and strategies to share. I don't use any traditional indicators, because just numbers are important for me.

    • Date : 01st June 2020. Events to Look Out for This Week.Geopolitics are back in the picture giving the markets pause and adding another layer of uncertainty to a shaky global outlook. However other than US-China tension, next week the global data dockets are heavy and results are likely to underscore the cratering in global economies this quarter. The calendar includes the US Jobs Report and Monetary policy meeting from RBA, BOC and ECB.Monday – 01 June 2020 Caixin Manufacturing PMI (CNY, GMT 01:45) – The Caixin manufacturing PMI is expected to slightly improve to 49.6 from 49.4 in May. ISM Manufacturing PMI (USD, GMT 14:00) – The ISM index is expected to slip to 40.0 in May from 41.5 in April, compared to a recession-low of 34.5 in December of 2008. Tuesday – 02 June 2020   Interest Rate Decision & Statement (RBA, GMT 04:30) – The RBA meet and are unlikely to move rates below historic lows at 0.25%, as RBA Gov. Lowe is his recent statement repeated that negative interest rates extraordinarily unlikely. RBA will maintain its expansionary monetary policies until progress is made towards full employment and we are confident on inflation . Wednesday – 03 June 2020   Gross Domestic Product (AUD, GMT 01:30) – GDP is the economy’s most important figure. Q1’s GDP is expected to slow down at 0.3% q/q and 1.9% y/y. Unemployment data (EUR, GMT 07:55-09:00) – The German unemployment rate in May is expected to have increased to 6.2% from 5.8%, while unemployment change is expected to have declined to 194K from April’s 373K. Meanwhile, Eurozone’s April unemployment rate should rise to 7.7% from 7.4% last month. ADP Employment Change (USD, GMT 12:15) – Lasts month, ADP report revealed a -20,236k April drop that undershot the -19,520k private payroll decline by -716k. For May a -9,000k drop is seen, since nearly all measures of activity rose in May from a trough. ISM Non-Manufacturing PMI (USD, GMT 14:00) – The ISM-NMI index is expected to rise to 46.0 from 41.8 in April. Most producer sentiment reports should show May rebounds after huge April declines due to mandatory closures, on top of the demand hit initially associated with the pandemic, and the oil price plunge with the OPEC price war, as re-openings are underway in most states. The April drop in the ISM survey was much smaller than the declines seen in other measures, however, and this is why we expect a further drop in May for that measure. Interest Rate Decision and Monetary Policy Statement (CAD, GMT 14:00) – On April 15, the Bank held rates steady at 0.25%, matching widespread expectations. In the next policy statement, the BoC is expected to leave rates unchanged, the Bank of Canada Governor Poloz said is his last interview that negative rates are needed only in extreme conditions. Thursday – 04 June 2020   Interest Rate Decision, Monetary Policy Statement and Press Conference (EUR, GMT 11:45 & 12:30) – Given that Lagarde buried any hope of a “mild” recession, the stage seems set for an extension of the PEPP program in size and duration at next week’s council meeting with an end date next year giving the economy more time to recover and EU aid programs to come into effect. Given that the ECB is no longer putting much hope in a quick recovery it is already clear that with the current time frame until the end of December that would risk a sharp widening of spreads in the second half of the year, when there is also the risk of a second wave of Covid-19 infections. Jobless Claims (USD, GMT 12:30)– US initial jobless claims contracted last week by -323k to 2,123k in the week ended May 23 after tumbling -241k to 2,446k previously. Claims have been declining since surging to 6,867k in the March 27 week. Friday – 05 June 2020   Event of the Week – Non-Farm Payrolls (USD, GMT 12:30) – A -2,200k May nonfarm payroll drop is anticipated, following a -20,527 April collapse, and a -701k drop in March. The jobless rate should rise to 17.5% from 14.7% from April, versus 4.4% in March. Nearly all measures of activity rose in May from a trough just after the April BLS survey week, but the initial and continuing claims data suggest a weaker labor market in mid-May than mid-April. Average hourly earnings are assumed to fall -1.0% with a partial unwind of the April distortion from layoffs being concentrated in low-wage categories. This would translate to a drop in the y/y gain to 6.6% from 7.9%. Labour Market Data (CAD, GMT 12:30) – Canada employment plunged -1993.8k in April, nearly doubling the -1010.7k tumble in March to leave a massive and rapid reversal in the labour market as firms cut jobs as most of the economy ceased to function amid the stay at home orders the began around the middle of March. For May employment should revealed a 4,000k drop in jobs, doubling again last months number. B]Always trade with strict risk management.
