PLUG and BLDP: End of the Rally?

BLDP and PLUG were on fire again gaining almost 25 and 15% each. At the end of the day I sold my position in DGAZ and took a 10% loss to buy PLUG at 6.65. Was it a mistake? I guess so. I let my emotions ruled my mind. Looking back at the charts now I feel this is the end of the rally for both the stocks and a pull back is evident. BLDP is in an oversold territory with a RSI of 98. It should soon pull back to $4.85. And that will be a great opportunity to jump back in for another leg up.

PLUG is also way overbought but surprisingly its RSI is low. Irrespective it has to fill the gap and I expect it to retrace back to 5.23. Same goes for PLUG, buy at that level for another rally.

One of the other rising star today was FCEL which is going to be a performing as well as BLDP and PLUG. Its RSI is still around 48 which still gives it a lot of room to grow. Now the question is should I wait for a pull back or jump in the rally? I think I will wait for it to gap up to 1.80.
