Estimate transaction volumn

[topfun]

I do search the forum but cannot find best solution.
I would like to estimate total transaction volume for daily trading. The market open at 9:00 AM and take lunch break from 11:30 AM to 13:00 PM and then continue transaction and close at 14:45 PM. With current speed of transaction, I would like to estimate total volume at the closing time will reach my expert amount or not. I am using Now(4) function but cannot figured out the final volume. Please help to advise. Thankyou

Below is my code

_SECTION_BEGIN("Volume estimate");
timev=Now (4);
IIf ( timev <90000 OR timev > 144500 ,Vole=Volume, // Before 9h and after 14h45 Vole=Volume  
      IIf( timev > 90000 AND timev < 113000,Vole = (Volume * 37500)/(timev-90000), //9h to 11h30//  
         IIf (timev >113000 AND timev< 130000, vole= (Volume * 37500)/(113000-90000), // lunch time
           Vole = (Volume*37500)/(timev-90000-17000) // afternoon
           )
         )  
    ); 

Plot( Vole, _DEFAULT_NAME(), IIf( C > O, ParamColor("Up Color", colorGreen ), ParamColor("Down Color", colorRed ) ), ParamStyle( "Style", styleHistogram | styleThick, maskHistogram  ) );

_SECTION_END();

For what it is worth, IIF is not control statement but a function. So you are using it incorrectly, see:

IIf function versus if statement

As mentioned by @fxshrat in ValueWhen - how to use a typical mistake users make is that they mix up if statement with IIf() function. IIf() (which stands for "immediate if") is a function, which means it takes arguments and returns the result result = IIf( condition, YesValue, NoValue ); It works with both numbers (scalars) and arrays. When any of arguments is an array it returns array. It goes bar by bar, checks condition again bar by bar and returns either corresponding array value from Yes…

I intended to plot the estimate of volume on current day (last bar) and keep remain original with previous bar.

Hi @topfun ( if your code is correct ?)

You have to add on your afl code the example below, to draw a volume as appear in your photo.
To change the position please adjust the BarCount + 1 to BarCount +/- 1
also adjust the width = 4 for the thickness of the Estimate Volume bar

// Original Actual Volume
Plot( V, _DEFAULT_NAME(), IIf( C > O, ParamColor("Up Color", colorGreen ), ParamColor("Down Color", colorRed ) ), ParamStyle( "Style", styleHistogram | styleThick, maskHistogram  ) );

// Estimate Volume to plot out with blue color
// This part of the code is for using GFX 
GfxSetOverlayMode( 1 ); 
GfxSetCoordsMode( 1 ); // bar/price mode (instead of pixel) 
GfxSelectPen( colorBlue ,width = 4); 
VolumeEstimate = LastValue(Vole);
GfxMoveTo(BarCount + 1, 0); GfxLineTo(BarCount + 1,VolumeEstimate );
GfxTextOut(""+VolumeEstimate, BarCount + 2, VolumeEstimate);

I had change the code as your advice, and it can run now,

Ok. as i read the above i thought your calculation is ok. and for that reason i wrote the "add on" for your code, and it is working ok . But.

As i read more carefully i realize you try to find the Volume of specific period of the day. I can tell, you need more help on this.
You multiply the Volume*37500 what is this number? was an example or what?

So you may need to read about SparseCompress() function , and i just try to give you an idea in below unfinished afl

a sample unfinished afl to work with
 
// lunch time
LunchTime = SparseCompress(timev >113000 AND timev< 130000,Volume );
     vole =  // your calculation here 
vole = SparseExpand( LunchTime, vole ); 

// afternoon
afternoon = SparseCompress(timev >130000 AND timev <144500,Volume );
       vole =   // your calculation here 
vole = SparseExpand( afternoon, vole );
