PRV -- Pro Rated Volume

[Tams 20]

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;

[Tams 20]

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

this indicator was written on TradeStation.

[danhoyda 10]

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).

[BlueHorseshoe 10]

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.

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.

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.

[onesmith 10]

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.

I'm curious what you changed???

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!

[onesmith 10]

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.

This is the best Prv_Volume indicator bar none. Unless Tams does something even more brilliant!
