Quote from DT3:
Can someone shed some light on this for me, I signed up for the free trial at MB and looking over their A and C values for CL I see they have a 8 tick value for A and 13 for C they also use a 45 minute OR. How is that possible my daily ATR for CL is at $2.30 if we take 20% of that we get 46 ticks, am I missing something here?
Another question I have was regarding the OR time to use. I know Fisher states that you should use the domicile opening for each trading product but I've found that the most volatile time and where a majority of volume is being traded is at the stock market open. What are your thoughts on using that as a standard OR for all products?
I would guess that the 8 and 13 tick value is not for the daily but the 45 minute opening range. Not sure how they derive that. Regarding your second question I assume you mean using 45 minutes as an opening range. If you think about it that is a pretty long time, there was some discussion of this earlier in the thread. I like to scalp so ten minutes on spy is a LONG opening range for me. So I would answer no to your second question, what makes sense to you logically? and what timeframe are you trading? if you are scalping spy for .20 or .30 cents then you want a tight opening range maybe 2-5 minutes. Also there is a difference between an opening range trade and the ACD method. The ACD A and C values are derived from X opening range period, you may want to look over the book again. At the end of the day you have to derive an A and C value that you are comfortable with and passes the test of logic for your trading sytle..........
