how do i custom code to calculate the value area of he previous individual trading day and show the areas that are heavily traded vol and calclate the support and resistance and display them on chart like in tradestation and TOS.

thank you

There would be no way for you to calculate the value area of a particular trading session as there is no way to speciify the start and end of a trading day in an intraday Indicator Formula.

I have not been able to figure out a way to create a formula short and fast enough to be practical or post in the forums for a version of this based on a period on an intraday chart either. It is theoretically possible to do so with the period set to the number of bars on the chart during a trading day, but the resulting formulas are just too long.

i thought their was more post about this topic, But is there away after the close of the day, to calculate the Value area Low for the day and the Value Area High for the day.  Basically to see Yesterday Value Area Low and Value Area High during todays session and Also the Point of Control of Yesterday

No, there is not. The basic case ends up being the idea of setting the period to the number of bars on the chart during a trading day as discussed in the second paragraph in my first response. Unfortunately the fact that it is only run at the end of the day does not make the formula any shorter or faster.

About the closest thing you are going to be able to do is to add a Volume at Price indicator to the chart in a fairly short time frame, zoom out to a day and kind of estimate where the top of bottom of the value area might be based on the Volume at Price bars.

Do the new shorter syntax create any new possibilities for this and the original post

It would shorten things somewhat, but not be enough.
