Hi,
Why not just draw an uptrendline on this multi yr. chart, wait till it's broken, & then setup your short for the long term. I would do this using a Trader Vic 2B test of top. You probably won't cherry pick the top, unless you watch it every day for the exhaustion gap run & reversal, i.e. the climactic run.
However, you could get in it for a very nice longer term position type trade, of the multi month, year variety. I've been waiting, & am watching for this also.
Good Luck with Your Trading!
God Bless & GFtY! Kelly
