that is some entertaining reading. thanks for posting it. this is an example of what i call the "gann cult". these people are off the wall and in no way represents how i use gann analysis to trade.

Quote from oddiduro:

Because the angles are based on a situation where the price and time axis were equivalent.

That means the 45 degree angle was not based on a rectangle, which is what your monitor shows, but on a square. Gann used standard engineering graphing paper to draw his charts, so that time and space could be accurately measured.



I can make a perfectly square chart with CQG and still accidentally manipulate the price axis simply by switching from bar to candlestick, or changing the width of the candlesticks. Angles also change as the chart formats itself to fit the high and low extremes on the screen.

For an extreme example of how a chart changes its own angles as new action emerges, check out a daily chart of THC. Before the huge gap down, there were rich angles in the ups and downs. After the gap down, all the preceding action becomes severely flattened out as a necessity of fitting that fat gap move into the chart. What you are viewing is regularly distorted by the mundane requirement of fitting the available price action into a specificed window, in lots of different ways, regardless of whether you have a rectangle or a square. Is there an optimal Gann setting for the width of the bars or candlesticks?? As Tharp notes, bar charts in many ways aren't really what's happening at all, they are an extremely limited abstract representation of what's happening- and thus prone to distortion and woefully incomplete.

A square chart still has arbitrary X and Y denominations. What is special about a man made unit of measurement, as measure of time and distance both are? We probably have a ten base number system because we have ten fingers and ten toes. We have a 24 hour/ 365 day system based on the rotation of the earth and orbit of the sun. What if we had eight fingers, or what if the earth was smaller and rotated faster, or larger and rotated slower, or took more/less time to circle the sun? How does squaring an arbitrary against an arbitrary create a meaningful statistical result?

Finally what does "equivalent" in terms of units mean? How do you match up price and time when both contain a series of potential infinites (both price and time can theoretically be divided into smaller and smaller units for eternity, or agglomerated into larger and larger units for eternity). Thus what is "one?" One to one of what? One second to one cent? One day to one point? One 6.5 hour trading session to one unit of average daily volatility?

Have a good weekend, and don't take me too seriously :-)
 
You say: I can make a perfectly square chart with CQG and still accidentally manipulate the price axis simply by switching from bar to candlestick, or changing the width of the candlesticks. Angles also change as the chart formats itself to fit the highs and lows.

I say: Correct again, now, with TradeStation you can disable this automatic formatting to keep the measurements intact. Remember that Gann didn't have this problem. Same with candlesticks and bars, this will affect the integrity of the chart and will throw the angles off. Initial measurements must be maintained for the duration of the square in question.

Insomuch as our number system being arbitrary, you are right yet again, but as we use this same arbitrary system to trade with (base 10), then the controls remain stable and measurements can be taken with accuracy.

All the Gann-ese is nothing more than a smoke screen to a few methods that Gann used to take price time measurements, and trade against those.

As long that the conditions for the initial measurements remain, then the measurements can be projected into the future with a very good degree of accuracy.

well said partner.
 
Maybe I was a bit harsh. Not saying these guys are stupid (obviously you aren't either), but yes, these guys are IGNORANT when it comes to Gann.

Quote from darkhorse:




Don't know why I'm bothering to respond to this, but I guess William Eckhardt and Jack Schwager are purely ignorant too. Eckhardt has a few hundred mil under management, Schwager had 80 mil last time I checked. From new market wizards:

Eckhardt: ...."There's a simple consideration that absolutely invalidates all such angles-of-certain-size methods in a single swipe: The size of an angle on a bar chart is not invariant to changes of scale. For instance, consider the technique of drawing a line from the low of a move at a 45-degree angle. If you do this on two charts of the same contract but with different time and price scales, say from two different services, the 45-degree lines will be different. They will subsequently intersect the price series in different places. In fact, the angle of a line joining two prices on a bar chart is not a property of the price series at all. It depends completely on what units you use for price and time and how you space them on the chart, all of which are quite arbitrary. There are good methods and bad methods, but these angle techniques are no method..... the lack of intrinsic meaning of angles on a bar chart has significance even for chart-oriented traders who do not employ angles. How sharply a trend slopes on a chart is often a psychological consideration in making a trade. If you fall prey to this influence, you're letting the chart maker's practical and aesthetic considerations impinge on your trading. Any trend can be made to look gentle or steep by adjusting the price scale."

Schwager: "I've always been amazed by how many people are either oblivious to the scale-dependent nature of chart angles or unconcerned about its ramifications. My realization of the inherent arbitrariness of slope-of-line methods is precisely why I've never been willing to spend even five minutes on Gann angles or works by the proponents of this methodology."


If I am an ignoramus, I take small comfort in the fact that two twenty year veterans managing hundreds of millions with proven scientific and analytical backgrounds are obvious ignoramuses as well.

If you are averaging 15 points a day per contract (minimum!) day in and day out, with use of nothing other than a few Gann angles, then you are a far better trader than I. So much better, in fact, that I am not fit to tie your shoes. I dare say your feat is akin to running a 30 second mile, throwing a 140mph fastball, or bench pressing 3,000 pounds. I can't even conceive with my small and limited brain how such a feat is possible given the natural restraints that general reality imposes. But I will not put my foot in my mouth again- instead of offering a further challenge, I will go and reflect on what I must be missing in my deep ignorance.

And that, my liege, is how we know the earth to be banana shaped.

Dude...we all can. I think you either aren't using the right tool or are not using it correctly.

It is amazing how a simple misperception can cause one to dismiss an entire methodology. I remember reading those quotes by Schwager et al. many years ago and falling into the mind trap of dismissing Gann, accepting those comments and thinking oh good I don't have to bother. Circle back ten years later, and now you'll have to pry the Gann Wheel from my hands.

I got lucky, I found Gann before Schwager, et al. By the time I found out that Gann is not supposed to work, it was already working!:)
