# Bermaui Deviation Percent

Or ( BD% ) is a volatility index that measures volatility in percent rather than points. The idea of BD% is to make an index depending on 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 term 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.

### Important BD% Parameters

Just started using it... looks good so far... will update after using for awhile. Might give 5 stars especially if author adds wav file capabilities for alert.

Edit: Reduced to 3 stars. Signals either late or useless (shortly after signal price goes in opposite direction). Also, weeks later, new version 6, and still no wav file audible alert on signal in order to check closely after audible signal.

Purchased your product some time ago. I just got back to using it, and I see that its been updated to version 4.0. I am grateful.

I have noticed however, that the candles on the chart do not follow the red/green/orange. Is this a separate indicator?

Also, is there an Bermaui EA, pls?

I have to give this indicator 5 stars because it is the only indicator that I can use with Bruce's strategy on the 1 minute chart. Plus, the develop is very helpful and will communicate with you. You will feel more assured after talking to the developer. I had a choice between this and TDO and I chose this because it works better with 3 EMA strategy. This indicator made it to where I do no need to rely on stochastic. Just simply look only for trades in the direction of all 3 ema's. Because it focuses on volatility, it removes the guess work
