ZSAN went from $2.27 to ATH $6.65 and closed at $6.00 yesterday; if you are looking to trade ZSAN this morning, here's an idea: if you are looking to "Long", wait for bullish confirmation as indicated with the "green" arrows for the stock to break above the "resistance" level and comes back to retest and bounch upward for an entry position; on the other hand, if you are looking to Short, wait for bearish confirmation as indicated with the "red" arrows for the stock break below the "blue" medium and comes back to retest that level and bounch downward for an entry position; good luck.
