ES in points. CL , NG in ticks. Per MarK Fisher ES etc are not suitable for his breakouut method. These are hardest to trade.
He uses it more for CL, GC, SI, HG etc.

I think that there are no official values for YM. Also I do not understand the ideas behind those values. For example the A value of ES is 7 times larger than the C value. For TF the A value is 2.5 times smaller than the C value. I think that you can use any value calculated from the average daily range, if you determine the best multiplier via a backtest.
My thought from reading the Logical Trader book is that Fisher has done extensive backtesting to arrive at the A & C values, which differ for each market. I agree with what I think is your point that these values change over time depending upon many different factors. Although I have seen that the CL, ES & NQ A values seem to be very accurate. I am looking at the TF market currently and don't have an opinion yet. The C value is very rarely touched, as it has to confirm the A value in the opposite direction before the C value is activated.
My feeling is that those values have barely changed over the last 10 years, and that the backtesting was done in the Nineties. The approach has certainly its merits, but I am not sure that results depend a lot on the suggested values for the A and C levels.
ACD has little to do with A and C values and more to do with context. Fish just gave A and C values as a refrence point. At the same time he said one should adjust A and C values based upon volatility of an instruement.
Just as there is no fixed OR for every trader under the sun. There is no fixed A and C value for different instruements. Some traders use 5 minutes OR, some use 15 minutes, some use 45 minutes and so on. A trader should try to understand why should he use 5 minutes OR vs 45 minutes. Similarly he should spend some time in understanding which A and C values will will be suitable for different OR. Volatility of an instruement for 5 minutes OR is different and thus different A and C values Vs 45 minutes OR.
General guideline is to use 25% of weekly Volatility range to determine A and C values. I know of traders who use 40% of daily ATR, some use 20% of weekly ATr and so on.
A and C values are a small component of ACD method. Try to use ACD for getting context. I personally use A and C values provided by Fish service. I later realize they are not as important as i thought. They are just one component of a system.
Time is more important than price. Traders waste time trying to figure out if A up is confirmed by trying to see if price stayed above a certian level by 2 ticks, 5 ticks etc. They are worried about ticks. They have little clue as to what 30 days, 5 days number line reading is showing and try to go long on confirmed daily A up when number line is -8 etc and get surprised all day long. If a trader finds it too overwhelming to track number lines, he/she should be able to look at daily chart and see trend.
Subscription service is avialable for fish service but traders waste 1 year, 2 years looking for simple answers because they do not want to pay for subscription service either.

I think that Mark Fisher uses an opening period from 8:00 until 8:40. I don't trade the opening range for GC, therefore I cannot give any recommendations.
