Importance of mid channel line in parallel channel tool.

Last 3 weeks or so we saw the Importance of mid channel line in parallel channel tool. Thrice Mid channel line supported the Nifty and Nifty bounced from there. When a support is taken multiple times mostly it becomes weak. This led to fall of Nifty below Mid channel line. Once the price is below the line which was a support. The line becomes a resistance. Mid channel line is now a resistance and the same line is stopping Nifty from going ahead since couple of sessions. It was an important lesson hence explaining at depth.

Nifty Resistance remain at: 18624, 18678, 18722 and 18778.
Nifty Supports present at: 18555, 18512, 18465, 18402 and finally 18371.
