DislikedIt has been an interesting few weeks since this thread has started. I enjoy the experience of having my own thread.

Although I think it has not been that popular a thread, I hope that it has helped some to understand the concept of using trendlines as support/resistance, to delineate a 'line in the sand' between uptrends and downtrends.

With that, this will be my last post for a while at least.

Cheers to allIgnored

DislikedI offer the following by way of critique of commonly held TA assumptions that everybody takes for granted and not as a critique of your efforts. Please carry on.

Common TA assumptions should be scrutinized by anybody who wants to trade with the probabilities. Ask the following question, how can 2 or 3 data points determine a trend? What about all the other data points - are they less significant than the ones that are cherry picked for trend line drawing? How about another question, why must a trend line be a straight line?

How can 2 or 3 data points determine a trend?

ANS: Well, the minimum you need to determine a trend are two data points. You cannot use one data point. You need at least two. This is mathematics. Now, for a given sample size, two may or may not be enough. It all depends on what you are looking for, what function you are using to plot these two data points together, what is the statistics noise level, etc. But just because you have two data points doesnt mean it is meaningless.

Also, the presupposition that you have two or 48 data points is simply contextual. That is, it all depends on the timeframe. Using the daily chart, a single data point is 1, but zoom to hourly chart, that same single data point suddenly becomes 24 data points. Since you've converted daily to 24hourly data. You can to this for monthly vs 1hour. In that sense a single monthly data point suddenly becomes an 720 data points(24hours X 30 days). As such, a 1, 2, 3 data points are all in the eyes of the beholder.

Why is a trendline a straightline?

ANS: In algebra, to draw a line you need at least two points. All algrebaic lines are straight. So, why wont a trading system(trendlines) based on algebraic concept of lines be straight? Of course, it will be straight. Trendlines are straight because they are based on algebraic concept of lines which are themselves straight. Unless you want to challenge the foundational concept of mathematics that derives straightlines.

Not to get really off topic, even curves and circles are straight lines when you use differential calculus limit/exhaustion method. dy/dx.

That said, any trend determining mechanics doesnt have to be a straight line: moving averages, elliot waves, series of swing highs/lows, etc. all these can determine a trend. But asking why is a trendline a straight line is like asking why is elliot waves a wave or why is moving averages averages. It makes no sense. the nature of trendline is to be a line, and lines are straight otherwise they wont be a line. Asking why a line is straight is meaningless, trendlines are lines, they have to be straight, otherwise, they wont be a line. This is axiomatic. This is a mathematical axiom. It is the same as asking why is a curve a curve or why is a triangle a triangle or rectangle a rectangle.

As prices derived from the auction process (market) are the end result of supply and demand form market participants, there is an inherent randomness and hence madness to market prices. By using assumptions and orderly structures such as trendlines and TA, one can get (hopefully) a more cognisant picture on which to make buy and sell decisions.

Thank you. Your response makes sense to me. We are all trying to impose some sorts of pattern on a chaotic market interaction. That is all. We are all working with approximations. The bottomline line is not the philosophical rigour of your method, the bottomline is: are you making money? That is the bottomline. Everything else can go out of the window

how do you know which direction to draw the trendline in order for it to break up or down? does it matter? do you consider larger timeframes when you draw your trendlines? when i look at your charts it looks so obvious but when i look at mine i dont know where to start!Ignored

The trendline is a 'line in the sand' between having a bullish bias or bearish bias. Say you choose the higher timeframe as 30 min (as in CAD futures attached) the larger timeframe 30m is showing bearish bias, so on lower timeframe trigger like 1 min etc you'd try to draw the trendline to go with the direction of the higher timeframe bias from which side of any trendline drawn.

Note: bottom chart 1 min top chart 30min

Hope it helps.

Cheers
