The important thing is to start adding Longs at or near the potential bottom, so one can have the time to properly evaluate new information and have the luxury of closing them if it proves to be necessary. Timing is important.
I'll just add I'm in this for the long run and not really interesting in taking advantage of minor price changes.
The positions I open on the Silver will not be closed until Silver is at least above 50$. Plan is to also add more on every decent retracement.
