People who listened EngineeringRobo's SELL signals such as Sell 2 on May, they saved 25% of their profit! (HELL & MA 20-MA50 signals also gives an alert after SELL 2 signal)
So, if you haven't bought yet, do not hurry to buy since the candles are still below resistance level ($4). I'd wait for EngineeringRobo's buy signals or wait for candles to reach back at resistance level ($4) to buy again.
