"maybe best to sell and buy back lower? anyone take this approach"

Don't know if you'll get too many giving advice on that Qn.
My opinion was that the selling time has well and truly slipped by. Maybe back at the 21/09/18
If you have a time machine would have been golden opportunity. lol
I sold way to late on the way down having way too much faith and not following anything but my heart, that and trading don't mix.
Will slowly accumulate shares again over time as I have to work on averaging it back down from some ridiculously high average that I don't want to talk about.
Again this maybe risky as the bounce maybe sudden and large and I may not have the numbers that I would like, but we all make our own bed to lie on.
