A secondary buy might be when the trendline from the 2 early tops is taken out (right at the previous day's close in this instance).
Another late day buy would be above the morning's high.
But it is likely that area will be tested on the next trading day so I would sell at end of day.
These are especially profitable in my tax free ROTH.
I also like buying or selling a long trendline break on the 5 minute.
Here's a similar pattern for NUGT Friday.
It shows why it's good to sell half and put the rest at breakeven.
