HD - Update - 325 could act as resistanceHD - This one has been a nice mover till now but things could start to slow down soon and we might then see a corrective pullback if this 161.8% Fib retracement level acts as resistance.
I don't know how deep the pullback will be once it occurs but better not give up too much of your profits in that case.
You can use the 50EMA or the ATR as a get out signal or at least to reduce your exposure by taking some profits.
