Taking images of charts and drawing lines on them? Looks like you're doing exactly what you need to do.
Now just start talking about patterns observed in your cherry picked snippet with any combination of adjective and shape. "That's a Bear Triangle!" "That's a Bull Ellipse!" "That's a Pensive Spheroid!" Don't worry, there's no standard duration, axis transformation, or trendline function. Feel free to plot log time against the square root of price for the last eleven minutes if it helps you illustrate your point.
It is important to end your TA post with an extremely strong, very bold statement about where the price is going. It's also important to be vague so that you cannot be held accountable later. But most importantly, this is the Economics Speculation forum on bitcointalk.org, so it is of utmost importance that you are making a bullish prediction. If you are making a bearish prediction, your methods will be criticized.
Hope this helps!
