I suspect this won't change many minds but I'll feel better for saying it: If you draw a trendline between 2 points only...it is meaningless!

Wikipedia as well as other mathematical sources define a line as:

In other words, a line connects two points. Connecting two points in space does not bestow upon you some magical powers for predicting a third intersection, it's just a line, no different than the ones you learned back in the days of crayons and diapers. Ever wonder why your lines are broken all the time? It was probably because they were useless to start with.

The addition of a third or more points starts to increase the validity of a line and you just might be on to something that is statistically valid. The more times that your line is tested and proven, the stronger it becomes and the more confident you can be about your trend-based trading decisions.

In**Euclidean geometry**, exactly one line can be found that passes through any two**points**.
