Ok, as we can see, FB has been breaking supports during weeks, but right now it is touching the EMA200, it is a strong support and has shown some rejection, it formed a green hammer that might be a morning star, specially with the volume so high, it might be a sign of reversal from this downtrend of the last weeks. Indicators are low and with a possible increase in the next days (MACD could give a buy signal in the next days). let's wait for confirmation, price could go up till 335 (stop loss would be under the EMA200) or fall below the EMA200, in that case, the down trend would be confirmed
