Do you leave your old Fibonacci retracement data on your sheet?

I think I may have fumbled with the ball slightly.

Do any of you traders leave the old data on your sheets? I normally deleted mine, more to keep things looking clear than anything else. It sounds stupid but I clicked that it might be a wise idea to leave them on in order to see some real solid support areas… I guess I could a horizonal trend line for each.

So, go ahead and tell me what a dopey doughnut I have been! - or not!

This is another one of those personal ideas.

I remove all but the last major swing (ie on GBP/USD 1.5234 to 1.63)

Then dependant upon the significance of the swing point I leave a S/R line.
