You cannot read about them. The idea is rather simple. Over a lookback period of N days, you just look how much price moves from the open to the high and from the open to the low of the session.
For each day the smaller of (high - open) and (open-low) is considered as noise. Then you calculate the N-day average of all noise values. This gives you an expectation for a threshold, where a breakout from the open may either succeed or fail.
The noise bands use two lookback periods, for example 10 and 20 days to take into account varying volatility. It is understood that the noise bands only represent the range calculated from the average failed breakouts. I may add standard deviation bands at a later stage to get a confidence interval.

The regular trading hours of 6E start at 7:20 AM Central Time. This is what I used. For trading hours see contract specifications on the CME website.
You can also display an opening balance for the London session. In that case I would either use 7:00 AM BST (British Summertime) or 7:00 AM GMT, once the DST is over. This would translate to 2:00 AM EST during 49 weeks of the year and to 3:00 AM EST during the other 3 weeks.

Every time, I have doubts about MF ACD system, i am proven wrong. On Tuesday, after long holiday , US market opened with all kinds of BAD news from Europe, China etc.. Market internals were wek all day, DXY had broken above $76 etc. However, once A up was confirmed at 1148- trade was to go long in 1145-1148 area.
Can you post an example as to how you use noise bands? if you trade WTI crude, that will be nice example. I typically have trouble figuring out failed breakouts ( before its too late) . Is noise band indicator available for down load?
The Session Noise is the smaller of (High - Open) and (Open -Low), which I consider the failed move from the open. The Session Noise Bands calculate the average size of the failed moves over the last n days. The indicator is available for download here:
The average noise over the last 20 days for CL was 65 ticks. The average daily range was 345 ticks. This means that id you use the noise bands as a tool to enter a trade in the direction of the breakout, when it retraces to the noise bands, your expected target is about 345 - 65 - 65 = 215 ticks. Of course this is oversimplified, as you need to apply confidence intervals to calculate the expectancies, but it shows the way to go.
The chart shows the noise bands for the last 3 business days.
Tuesday: CL10-11 broke out upwards from the noise bands and retraced to the upper band. The pullback was the ideal entry for a long position. The target band - representing the average daily range (ETH) - was reached later during the session.
Monday: This was a holiday session. CL 10-11 had made a larger move during the European morning. The US session was quiet, as CL 10-11 mostly stayed within the noise bands. At the end of the regular session the daily range target (ETH) was reached after a weak breakout.
Friday: There was no valid breakout as CL 10-11 stayed within the noise bands during the US session. Nevertheless the daily range target (ETH) was reached as well, as there had been a large move prior to the opening to the US session.

First I want to thanks for your work.
I would want to apply those indicators on the ES and I've tried to replicate to see If I was doing well, your CL chart, but I can't put the noise bands just for the american time, they appear extended to the all day. I dont know if it is cause you are working with the V37 and I have the V34. And I also do not have the V38 volatily band, could be for that that it doesnt matchs with yours?
Since the ranges on the ES are smaller, do I have to change something on the Options/Parameters of the indicator?
Could you sugest me something please?
Thanks a lot by now,
PS: And could you also send me the page of those indicators (volatily Bands) ? I couldn't find those.
