On 5m bars:
Q: What is the minimum number of bars needed to draw 2 parallel lines (points 1,2,3)?
A: 2.
Two bars give 4 end points. You use 3 of them to get the lines. There are exceptions to this, which everyone here knows.
When you draw the lines off 2 5m bars, you can bet your ass that is not the "best" channel to operate on. I use the word "best" here from the viewpoint of a beginner whose focus should be on growing his account and building up confidence. Call that channel a traverse. Oftentimes the 2 bars are similar in volatility. The bars that follow will be too. Give this an additional name: a tape. But don't forget, the channel you just drew is a traverse.
Q: What is the minimum number of traverses needed to draw 2 (wider) parallel lines?
A: 2.
Two traverses give 4 end points (one overlaps). You use 3 of them to get the lines. If the second traverse exceeds the extreme of the first, you wait for the next traverse.
This is the "best" channel to operate on. In Spydertrader's examples, this is the red channel. Look for the "best" places to extract from this channel. Again, I'm using "best" here from the perspective of a person looking to grow his account and build confidence.
