Here's a couple of levels that could be interesting to you. I'll zoom in on the 1984/87 levels to show you why.

I took the s/r levels off the monthly chart looking at prices that occurred in 1984-1987. This is the current time and it's still reacting to the same principles as it did back then.
Breaking 1.2920 would mean we could potentially see 1.1880. Sad times for our British coins.
