you are correct, I usually chart GDXJ
and I screwed up the trade for myself and missed the JDST 30% pop and likely more today, was in JDST at 10 then exited when it dipped to 9, sticking with my stop rules and moved on to other trades
I don't want to enter JDST now when congress can come any day and announce a stimulus bill agreement since they apparently went back to negotiations, I'm sure the shiny metal will reverse hard again with another trillion or two !
