Another question...

Is there a way to formulate an Average Price (midway between the Low and High of the day) which can be added to a chart as a "Custom PCF Indicator" so that one can use the "Crosshair with Data Box" over each day to see that Midway-Price?

(H+L)/2

You can leave it in its own pane or move to the price pane and scale with price.

I see that this works on the chart as long as one is careful to place the Crosshair exactly over the line.

How another question, again using JDST as an example.

When I place the Crosshair over 3/21/17's line, the Midway-Price is no longer correct.

Also, when I add a column PCF Indicator using H2-L2/2, it says the Midway-Price is $8.20.  The correct Midway-Price should be $12.94.

How do I need to change my H2-L2/2 Indicator to use it as a Column?

You really do need to use the parentheses given in StockGuy's reply.

When you use (H + L) / 2 it adds together the high and the low and divides the total result by 2. This is the midpoint between the high and low).

When use use H + L / 2 it adds the high to half of the low. This is always going to be higher than the midpoint between the high and low (well unless the high and low are both equal to 0). This value will normally be much higher than the midpoint between the high and low.

And yes, you do need to put the pointer on the correct date in order for the value listed for the Custom PCF Indicator in the pointer mode data box to be correct for the desired date, but that is true of all of the indicators in the pointer mode data box, not just Custom PCF Indicators.

Works!

I am happy to read it worked for you.
