Those S and R values are not too far off the ones I got from the Camillari calculator kindly posted by Tenapenny.
Using that, and seeing we'd gone below S3, way below, I could see a bottoming, and went back in at just 50p a pip to test if the market would come back to S1, or S2, this possibly now becoming a new resistance level. Anyway entered at 14885 on the way back up, and set for just below S1 at 14915, so a nice 30 pips there, although at 50p its only £15. still that has added to my £8 this morning, for a reasonable gain given my £1/pip limit. And just looking, I could have held for more, but that'll do.
So thanks to Mike and Tenapenny for these fantastic tips, and I for one will remain keenly watching this thread, for it's diverse inputs. I think whatever pivot calculator method you want to use, it should demonstrate the nearby supports and resistances, to further verify the NT rule.
NT+D, see?
I feel I've learned a lot this morning. To my day job's detriment mind, but thanks again!
