Bruce, is it possible to create a PCF for the standard deviation of only the first 30 minutes starting at the open of the day in TC2000?

No, it is not possible.

We can create a 30-period standard deviation formula and you can plot it in a 1-minute time frame by adding a Custom PCF Indicator to a 1-minute chart.

Adding and Moving Indicators (7:19)

- Period: 1
- Average Type: Doesn't matter (because the Period is 1).
- Formula: SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 + C7 ^ 2 + C8 ^ 2 + C9 ^ 2 + C10 ^ 2 + C11 ^ 2 + C12 ^ 2 + C13 ^ 2 + C14 ^ 2 + C15 ^ 2 + C16 ^ 2 + C17 ^ 2 + C18 ^ 2 + C19 ^ 2 + C20 ^ 2 + C21 ^ 2 + C22 ^ 2 + C23 ^ 2 + C24 ^ 2 + C25 ^ 2 + C26 ^ 2 + C27 ^ 2 + C28 ^ 2 + C29 ^ 2 - 30 * AVGC30 ^ 2) / 30

Modelling Bollinger Bands (& Standard Deviation) in a TC PCF

But it is only going to represent the first 30 minutes of the trading day on the 30th 1 minute bar of the trading day. Every other bar is going to return values for a different 30 minute span.

Note also that while you can plot the indicator in TC2000 Gold, you would need TC2000 Platinum to use intraday calculations as sorts or EasyScan Conditions.

Thank you Bruce,

I came up with the same thing, but was hoping I could stop it at the 30 min mark rather than continuing to update each successive 1 min bar.

There is no way to automatically the calculations at the 30 minute mark.

Bruce,

would it be possible in StockFinder?

Yes, it is possible to do this in StockFinder Platinum.
