A wonderful indicator that filters out ranging and trending market effectively on m15 TF. My entry improves.
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.

A wonderful indicator that filters out ranging and trending market effectively on m15 TF. My entry improves.

This is the best and easiest indicator I've bought. 2 days in and I made 100 dollars already. Thank you sir for this great product! 10 Stars!

Bermaui Bands and Bermaui Deviation % work well together. I got good results soon after installing the great tools. Any trader worth his salt shouldn't trade without this duo. And thanks to the author for his superb support.
These products are worth 10 stars and more.


interesting idea.............also has an implied flat filter..........does not repaint...........can be a good part of a strategy

Just got the Indicator and so far I like what I see. Ready to start using the ind this week. Thanks Muhammad for sharing your knowledge with us. Much appreciated.




The indicator is very helpful for my trading with other indicator for confirmation. Recommend it highly.

The Indicator is very helpful. It gives you extra confirmation for trend direction and momentum both. Worth buying it. Nice work!


I like this indicator, even better when combined with Bermaui Bands

Good indicator. Very good in combination with other indicators like "Bermaui Bands". Thank you Muhammad.

Its a great tool and when combined with the Bermaui Bands, you then have a WEAPON of confluence.

Good and honest indicator. Does what it says.
Great tool for a trading arsenal.

the first indicator I bought from market. very nice and effective indicator. good filter.

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.

BAD INDICATOR all people here post good comments and give 5 stars because the author gives "FREE" another indicator named MASR Bands that indicator is nice but the others are not accurated.

Hello, I bought two indicators, Bermaui Deviation Percent and True Direction Oscillator, which are very useful to me. All five stars.

Never found such a well respectively perfect indicator before - really worth buying it - 5 stars are not enough...

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?

Works really great. Now I can find the trade which is really trending!

Excellent indicator for identity range and trend market! plus good additional functions such as Zig Zone Levels to easily capture support & resistance.
Recommended to my few friends.They all bought and are very satisfied. Highly recommended!

شكر لك اخي محمد الموشر يستحق الاقتنا وان شاء الله سوف اقوم بشراء باقي الموشرات

This indicator is a treasure for those who follow it
Sales Guide to 1000
Thank you Professor: Mohammed

Very helpful indicator to be used with other systems to confirm the strength of a trend, excellent work.

Another 5 star indicator, it does exactly help to judge and work, highly recommended!

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


This indicator is awesome. All you have to do is follow the rules and you will make profits all the time. This indicator goes great with the true direction oscillator. Excellent.

Perfect volatility and trend impluse indicator, works great with your bands indi, good price too!!

such a great tool, you could use this indicator to trade happily. works on all time frames

Great Indicator when you can use well . Thank you for your great work Bro.!! If I could I would give you 100 stars!!

Plus BB all indicators very useful for trading. Developer quickly answer questions.

very nice and effective indicator for identity range and trend market

BDP is a good additional filter for me. I use it together with TDO and some other indies.

I like the developer ideas and how creative he is.
Im still testing BD% and so far great use for 1Hr chart.

A really good indicator ! Simplifies entry on trends and avoid choppy sideways movement.

This indicator is helping to find choppy markets and trending markets. Want to use it has a filter.

It is more than a simple indicator, it includes in itself a set of tools that allow you to implement and operate more than one system or implement it to any type of operation, a very versatile and accurate tool at a very convenient price, you receive more than what you pay :)

Good Indicator... I used it with other indicator for confirmation, performs well, very helpful for me. thanks..

I used it on renko + other indicator for confirmation & it performs very well .. It filter choppy market & sometimes give me signal for early entry on upcoming strong trend. very good!

The indicator is very helpful to filter some "bad" signals during a trend or in trendless market. I like it and he helps me to get accurate signals.

Filters choppy trades and controls our trade in buy/sell side... it is nice to see a good supporting tool for placing orders
