Dow futures down -138 at this posting.
Just btw, no pro I know watches DJIA; rather, they watch SP500. A bigger selection sample is almost always better to use for analysis. In any case, there are far, far better and easier mkts to trade at this time, e.g. coffee, sugar, crude and products (short term only).
A short wheat position rates to profit handsomely once the Ukraina situation sorts itself out, say over 2-3 weeks' time. Too early to enter now; perhaps by the end of this week. If short wheat is too risky for your tastes, use the bear spreads instead, maybe long N, short K or long Z short U.
Also, the instability created by the Fed and declining real earnings have set up and are still setting up excellent double vertical spread opportunities in natively volatile stocks on the day before they report earnings.
Good trading to you!
