DTO is a great example of how I try to trade (not currently holding, though :~(
On the daily, it has been extremely overbought for 4 days in a row. That's the most I've seen for any stock I've watched (or index) EXCEPT for TBT that closed Thursday at 5 days in a row extremely oversold. (Overbought or oversold= 4 days max, usually :~) )
Now, it looks like DTO will be down about 12% or more Monday if the futures hold where they are now as I type (43.26/bl).
So, 118-121 likely for DTO on Monday.
