Greetings to the denizens of '02 from the future.
There has been some discussion lately about bar intervals and timeframes and going for the "big turns" and the "big moves" and whether trading price is superior to or equivalent to trading with indicators, particularly the MACD, and whether and how an indicator such as the MACD can aid in automation even for one who is trading price, i.e., a "PA" trader. And I was reminded of this thread in which I participated and saw no reason to start a new one since this one has only 15 posts in it. A quick 'n' dirty thread, if you will.
I provided an explanation of the MACD at the beginning, so I needn't go into that again. As for the now, the subject of oil came up, and since I first posted about the PA in this chart two months ago, it was interesting to see it brought up again today.
I used to be a fan of the MACD before I moved on from it, but if I were going to explore automation (which I won't, but 40D is interested), MACD is what I would use. And while it's not as simple as it might seem, it's not terribly complicated. As I point out earlier in this thread, 13 years ago, it all depends on what one wants. Which is likely the most difficult decision.
If one is going for the "big turns", he must of course use the weekly chart (he can use the daily, but the signals are far muddier). Given that, there are at least three options: enter at the first sign of countermovement in the histogram, at the first uptick in the MACD, or at the cross. I've noted the bars at which each entry would be made. All of these are "too early", as is so often the case, but price does hold and make a double bottom when it tests 44 a second time, and if one doesn't mind the opportunity risk, nothing is lost by entering and holding. This is, of course, hindsight, and price could just as easily have fallen through 44 on its way to who knows where. Still might. The last time this happened, price based for three months, and the three months are just about up.
The second chart shows how this would be traded via PA. But there are choices to be made here as well: assume the opportunity risk and buy when the stride is broken, buy the double bottom, short a failure of the double bottom if and when it occurs, buy the breakout through the top of what has become a range by the time the double bottom is made (this range is more easily seen on the daily). Which choice one makes will depend on what balance one seeks between price risk and information risk.
