Hi, I am trying to make a PCF with bollinger %B
with a bollinger average of 5 and a stdv of 1.
How can I get the pcf with the rule that the %B closes below 0.2 for three days or more?

Please try the following:

(C - AVGC5) / SQR(ABS(C ^ 2 + C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 - 5 * AVGC5 ^ 2) / 4) / 2 + .5 < .2 AND (C1 - AVGC5.1) / SQR(ABS(C1 ^ 2 + C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 - 5 * AVGC5.1 ^ 2) / 4) / 2 + .5 < .2 AND (C2 - AVGC5.2) / SQR(ABS(C2 ^ 2 + C3 ^ 2 + C4 ^ 2 + C5 ^ 2 + C6 ^ 2 - 5 * AVGC5.2 ^ 2) / 4) / 2 + .5 < .2

Thank you very much, that works excellent.
Could you also provide me with the PCF for:
The smoothed RSI2 from today < smoothed RSI2 from yesterday?

Hi Bruce
How about PCF for %B using std settings of 20,2,0 with readings of 1.0, 0.5, 0.0 showing on the right side of the window.
%B=1.0 where price exactly on Upper Band
%B=0.5 " " Middle Band
%B=0.0 " " Lower Band
I intend to sort them by exact value.

Using the PCF provided from this site, i am able to plot BWI ( band width index)which matches exactly as those generated by others (Stockcharts)
But the readings on the right side of the indicator are completely different.
TC gives reading of 0.051 to 0.147
Stockcharts " 1.5 to 4.0 , both using same setting (20,2,0) on CSCO today.
Can TC readings be changed to match those in stockcharts for easier interpretation?
Thank you so much
jfisamm

jfisamm,
The formula would be:

(C - AVGC20) / 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 - 20 * AVGC20 ^ 2) / 19) / 4 + .5

You can use this as a Personal Criteria Formula or use Indicator Sorting on a Custom Indicator to get sorts using exact values:

Create your own stock rankings using WatchLists and Sort conditions
Plotting Custom Indicators with Examples
Sorting price and indicators by their Actual Value

I do not know a practical automated method to force the desired scaling or lines in TeleChart. It is possible to specify the scaling and set Value Pointers in Blocks.

jfisamm,

The PCF given by Bruce is correct for TeleChart. For all other charting services (as far as I know) including StockCharts, the "/19" must be replaced by "/20".

Thanks,
Jim Murphy

jfisamm,
This (/19 vs /20) is discussed in more detail in the Modelling Bollinger Bands (& Standard Deviation) in a TC PCF post referenced in my first reply in this topic.
