Bermaui Deviation Percent


Or ( BD% ) ⭐⭐⭐⭐⭐ which is a volatility index that measures volatility in percent rather than points. The idea of BD% is to make an index depending on the Classic Standard Deviation (CSD) that moves between 0 and 100 percent.

You can use BD% to compare volatility for the same security in different time periods or different time-frames. In addition, you can use BD% to compare volatility between different securities in different markets in terms of percent rather than points.



The idea behind this indicator explained in the next steps:

1. Calculate Classic Standard Deviation (CSD) for X number of days.

2. Find the Highest High of CSD in the same X number of days ( = HHV(CSD, X) ).

3. Find the Lowest Low of CSD in the same X number of days ( = LLV(CSD, X) ).

4. BD% = ( HHV(CSD, X) – CSD) / ( HHV(CSD, X) – LLV(CSD, X)).

How to use "BD%"

• If BD% is under 90% and then crosses this level upwards, this is a sign that prices may move in a ranging area.

• If BD% is above 90% and then crosses this level downwards, and the price is already above its simple moving average, this is a sign for the beginning of a new ascending trend. As BD% gets deeper to the downside, volatility and trend strength are increasing. When BD% is 0%, this means that volatility is at its highest value.

• If BD% is above 90% and then crosses this level downwards, and the price is already below its simple moving average, this is a sign for the beginning of a new descending trend. As BD% gets deeper to the downside, volatility and trend strength are increasing. When BD% is 0%, this means that volatility is at its highest value.
