I wanted to build an indicator that would visualize the volume of the current bar relative to the prior bar, in this way:

- how much volume of current bar is above the prior bar high?
- how much volume of current bar is below the prior bar low?
- how much volume of current bar remains as 'inside' volume relative to prior bar?

But I admit I am having a hard time getting the logic right to do this.

// current price higher than prior bar high
if C > H[1] then begin

outside_volume = ???;

end;

My issue is with tracking the outside volume amount. I'm using intrabarpersist on the var: definition, but the values are coming out as cumulative which is not what I want. So then I tried adding a BarStatus(1) = 2 check to reset the value at the close of each bar, but again desired effect is not happening.

Maybe someone can see an easier way.

Here is code and a screen shot. Doesn't work as-is, I need to step away and think apparently

 
Code
vars:

	IntraBarPersist outsidev	( 0 ),
	IntraBarPersist outsideupv	( 0 ),
	IntraBarPersist outsidednv	( 0 );
	
//if BarStatus(1) = 2 then outsidev = V;
outsidev = iff(C > H[1] or C < L[1], outsidev[1] - outsidev + V, outsidev);
//outsideupv = iff(C > H[1], outsidev - V, outsideupv);
//outsidednv = iff(C < L[1], V - outsidev, outsidednv);

Plot1(outsidev, "Outside Volume");
//Plot1(outsideupv, "Outside Up Volume");
//Plot2(outsidednv, "Outside Dn Volume");
You can see the couple different ways I've tried it.

....the values are coming out as cumulative which is not what I want.

This is a great idea Mike. I've tried to make it work, but ironically I can't get the right cumulative values. My problem is that the first tick of the bar seems to get missed, though I've no idea why. If you, or someone else, can spot the error in my code, that would be a great help (and potentially 'solving' this problem).

Here's the output, note the line with error:

1110516 102043 Price: 107.445  prevBarClose: 107.445 DOWNvolume: 1 totalDownVolBar: 435 volThisBar: 1829
Note the volume in the variable 'volThisBar' of 1829... the volume in MultiCharts playback is 1828. One (!) missing tick makes this code incorrect. I don't mean that obsessive - if that one trade had a volume of 200 contracts the difference would be quite huge, so this error needs to be corrected.

Btw, I know that I can use 'volume' instead of custom calculating the volume of the bar (in the 'volThisBar' variable), but there shouldn't be any difference between the 'Up volume this bar' and 'Down volume this bar', given the conditional statements in the code.

Btw: I haven't incorporated your idea yet in the code Mike, since this version is a test to see if the underlying calculations/assumptions are correct. If they are, the logic can be easily changed to any condition.

And the code:
 
Code

    ;

Thanks for your help, I will take a look this weekend and get back to you.

I think I've got it fixed (will need to do more testing to know for sure).

I've added the following in the BarStatus(1) = 2 section:
 
Code
                            
    Print(date:6:0" "time_s:6:0" upVol: "totalUpVolBar:0:0" downVol: "totalDownVolBar:0:0
        
" volumeOfBar: "thisBarVolume:0:0" defaultVolume: "Volume:0:0); 
If the code should be correct, the 'volumeOfBar' should equal the 'defaultVolume', which uses the volume provided by MultiCharts.

Here's the output of that statement:
 
Code
1110516 100155 upVol: 30518 downVol: 740 volumeOfBar: 31258 defaultVolume: 31258

end
I'm wondering how this might be added for historical charts - the current version only works on real-time data or Playback. Adding a data series with a 1 tick resolution messes up the layout of the primary data series, which makes this not a viable solution. Anyone got an idea?

Regards,

See attached nexusfi.com (formerly BMT) Outside Volume indicator. Usable on real-time data or PlayBack data.

Perhaps the plot style can use some further styling (I'm not sure this is the most clearly visible style). Any other feedback is off course highly welcomed.

Regards,

Very nice, Jura. Sorry I've had no time to do any more with it. I have been so busy lately, and today I just kind of zoned out and watched TV and tried to relax. But I'll look at your indicator shortly and appreciate your help.

Mike

Hey Mike Jura

Happy anniversary & 4th

Not quite sure what the function of this ind represents, any way I've been wondering about an indicator or script where volume would affect the actual price bar body in a way that if there was say a >500% volume increase then the actual Bar would expand relative to the chart to show this, no need for another viewing pane, is there such an indicator already or is this even possible?
