Can you please help me with the following indicator?

(Bottom - Top) / Middle Bollinger Band(20 SMA,2 SD)

Where...

Bottom = abs(Lower Bollinger Band(20 SMA,2 SD) - Lower Bollinger Band(50 SMA,2.1 SD))

Top = abs(Upper Bollinger Band(20 SMA,2 SD) - Upper Bollinger Band(50 SMA,2.1 SD))

SD = Standard Deviation

Thank you.

Please try using the following Indicator Formula as the Formula in a Custom PCF Indicator.

Can you also please help me with the following additional period settings?

(Bottom - Top) / Middle Bollinger Band(10 SMA,1.9 SD)

Where...

Bottom = abs(Lower Bollinger Band(10 SMA,1.9 SD) - Lower Bollinger Band(20 SMA,2 SD))

Top = abs(Upper Bollinger Band(10 SMA,1.9 SD) - Upper Bollinger Band(20 SMA,2 SD))

SD = Standard Deviation

Thank you for your continued help.

What's the forumla for Upper Bollinger Band (20 SMA, 0.5 SD) at Close yesterday and Open today? Thanks

And forumla for Upper Bollinger Band (20 EMA, 0.5 SD) at Close yesterday and Open today? Thanks

The simple upper Bollinger Band 20,.5 at yesterday's close would be the following.

AVGC20.1 + .5 * SQR(ABS(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 - 20 * AVGC20.1 ^ 2) / 20)

The exponential upper Bollinger Band 20,.5 at yesterday's close would be the following.

XAVGC20.1 + .5 * SQR(ABS(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 - 20 * AVGC20.1 ^ 2) / 20)

The simple upper Bollinger Band 20,.5 at open today would be the following.

(O + 19 * AVGC19.1) / 20 + .5 * SQR(ABS(O ^ 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 * ((O + 19 * AVGC19.1) / 20) ^ 2) / 20)

The exponential upper Bollinger Band 20,.5 at open today would be the following.

(2 * O + 19 * XAVGC20.1) / 21 + .5 * SQR(ABS(O ^ 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 * ((O + 19 * AVGC19.1) / 20) ^ 2) / 20)
