Reduce positions

Today I sold all DBC and a small portion of POT. I bought a very small position in KOL (Coal related ETF).

1. Recently, my DBC position turned out to be the best performer, too bad it's small. Since oil run up $17 in two days, I took profit in DBC and raise cash.
2. Also sold some POT for good profit, I bought them at 180s and 190s. Raise cash.
3. Bought a small KOL to monitor this sector. Comparing to oil, coal is cheap, so I'll use this ETF to monitor the sector. May add more in the future.
4. DBA and DAG are almost back to the price I paid, a few more days like this, I'll be in black.
