Quote from traderdragon2:
If trendlines had any ability to predict future price movement, then it would be easy to program a backtest that could 100% prove this.
Picking high points and low points and drawing a line between them is something that can easily be done by a computer.
Ive heard of no such results. Sounds like reading tea leaves to me, and being fooled by randomness as is usually the case.

as i said, not a subject to start a new religion over, but just a tool. go over to stockfetcher and look at their "channeling stocks" which, while channeling up and down the LRC, are actually moving within two trend lines.
if a stock has moved for 5 months in this same channel, it is thought that it shall continue until it doesn't any longer. if you had looked at the chart months ago, you would be far ahead in bucks at this point --- just cant agree that they dont foretell, but also not saying they're the end all and be all of TA either !
to the poster who speaks that TA doesn't work 100% of the time, NOTHING DOES, but we are in, and have been in, a TA market where traders watch support and resistance and buy and sell accordingly UNTIL news changes the situation and establishes a new trend !
one can draw lines anywhere, but after a few years one gets to "feel" where trends have changed and re-draw from that point -- one look at a chart should show that easily enough.
now ive spoken about backtesting before, and simply put, i dont use it or believe in it, as the success of the trendline and the stock or currency im watching is all the "backtesting" i shall ever need. Now maybe my trading style (core position on a rising or falling symbol and long the rally and short the dip within the trend lines) doesn't fit with the backtesting method, i dont know (and actually, dont care either) but the trendlines work for me, provide me a guide to where the symbol SHOULD be at its high or low, and if it violates that trendline, gets my attention quickly.
guess what im saying is i have no use for backtesting, as i can see what a stock has done, is doing and pretty much what it will do !
my opinion and style, of course !
