Familiar with Technical Indicator?, "Percent B"

Hi. This is my first post.

I have this indicator in my stock trading platform, Fidelity Active Trader, but I have not been able to find a forex broker who has it in their charting software.

Do you know of any brokers that offer this indicator?

If not, do you know where I can find more information about this indicator and/or its formula?

Thank you.

    Hi Chris1010

    Im not familiar with your brokers platform so cant be 100% sure. However John Bollinger in his book on bollinger bands describes an indicator that he calls %b. This indicator basically tells you where price is in relation to the upper and lower bollinger bands.

    The indicator displays a value of 1 when price is at the upper band, 0.5 when price is at the central band, and 0 when at the lower band. The indicator may also go above 1 and below 0 when price moves outside the band

    Its an easy enough indicator to calculate:

    %b = (price - lower band) / (upper band - lower band)

    It might be worth sticking bollingers on your chart and comparing to the %b indicator to confirm. I may even have a custom indicator i programed for metatrader somewhere, happy to share if it helps.

    I havnt seen %b on any brokers platforms but I havnt really much experience in that area.

    Zupcon,

    Thank you for your detailed reply. It really helps.

    If you could find that formula for Bollinger Percent B and post it here or email it to me that would be great.

    Thank you.

    %B = (Close - Lower Band) / (Upper Band - Lower Band)

    Multiply through by 100 to get a base 0 to 100 scale. Keep in mind, however, that sometimes the value will exceed those bounds if the market closes either above the upper band or below the lower band.
