Over the years Zion Oil has traded in a pattern that never seems to change, right now it's stuck in the 30 +/- 10 cent range. Buy on one end, sell on the other. Don't rush, don't get greedy, and don't buy the hype. It has been working for me. The only problem with this NOW is the SEC investigation. In order to make money at this, you need to put in maybe $100K when you buy, but the SEC investigation is the wild card, and if they shut this puppy down while you have $100K in it, you're toast.
I've dropped my play down to the $30K level because of the SEC overhang. If you are patient and don't mind waiting 6 months to a year to trade, you can easily make $25K in about one round trip trade per year without much risk at all.
Looking to see $0.20 before we see $0.40 (and it might take up to a year for this to happen). Don't trade blindly or hurriedly, be sure to use "good 'til cancel'd" sell orders, and good luck to all, especially the longs. They will need it.
