Here is a weekly chart from Elliott_Trader. A link to his site with more charts is here

The EW debate for the most part is whether a major wave 3 or wave 5 is concluding but in any event a correction is likely now. A five wave pattern on TZA has not formed on a small time scale so there is no buy signal in the inverse ETFs yet. However based on proximity to EW targets and other indicators IMO we are close to a sell off here.
