I am mostly positive about ZRX. Engineering Robo is giving a Buy 2 signal. In addition, the MA 20 (blue line) is above the MA 50 (yellow line) indicating that it is time to buy it. If the candles continue to go up and pass the 0.4826 resistance level with an open-close candle, I can buy it. If, however, the candles move down, I can wait for a hell or sell signal to sell it.
