thanks for the kind words
The important thing to take away is that the feedback mechanism between the internal and external markets... Because of people exploiting the arbitrage, the (lower priced) internal market is able to pull the external market prices back down when they start to go up. There have been a couple of times ive watched at least a small recovery started, then be smacked back down by arbitrage volume.
Great point, I amended my initial comment to highlight that point.
