Wondering if anyone can help me here, I am not a coder. Was wondering if anyone can make an indicator that one can draw a box on there screen for a particalar area of bars on a chart then click on it and it will give you the total volume for those bars. This could help on a quick evaluation of volume in a particular area instead of having to count each volume bar. Thanks Hector, sorry to bother anyone but I thought this could be helpful and I am not a coder.
I'm gonna go out on a limb and say that what you're asking is a pretty tall order....
The indicators and functions in platforms don't allow for interactive graphic interfaces like you're describing.
Your best bet would be to simply add an indicator that calculates the total volume over a historical range. You can make the indicator input vary the range. That way you'd know that value for the current bar.
If you're looking for spot, custom probes for calculated volume over varying amounts of bars, that would involve some serious GUI coding that's really beyond the scope of programming environments.
Like I said, I think the closest you'll come is to have an indicator that you can specify the number of bars back to calculate the total volume...instead of highlighting an area, you'd input the range and it would give you the value you're looking for on the far right bar of the interest "area."

I'm not familiar with C, and I'm just now getting a handle on Easy Language, but you should be able to learn pretty quickly how to develop simple indicators like discussed above.
If the platforms he recommended will work, great. Having an "indicator" that calculates custom specified calculations based off a graphic user interface (such as highlighting an area with a mouse) seems pretty intricate. I'd be interested to see the outcome of this.
In the interim, it's pretty simple to code your own indicator that as I said, you'd simply need to enter a user defined input such as "number of bars back" that would output a total volume for each bar.
That way, you could keep track of say the last 10 bars of total volume on any given bar and use it as an indicator to whatever end you choose (I'm assuming you're using it for entry criteria/screening).
