How should you draw your chart? ... Do you have any ideas? ... What if you don't have any ideas, and you don't know what to do?
...Calm down... pull your pencils out. Its time to start learning, and teaching...ourselves!
Thats generally a good rule to follow. So places where you find a ton of support lines all built together are probably pretty safe from penetration. With that in mind when you look at fib arc's try to view those support regions as a powerful force pushing the price action away from them. ...No force cannot be overcome - but it takes pressure and time to break through right? ... That would be my suggestion when choosing which arc's to eliminate.
Furthermore Arc's which backtest so support/resistance on the left side, typically will show us hidden areas of resistance/support on the right side (projected side) as well. That's always a key determinant.
