Strategy Rules

The strategy is a close cousin of TuringTrader’s Quick-Change strategy. The most notable differences include a slightly different money-management scheme, and the risk-off strategy. While Quick-Change caps the maximum exposure to a single stock, this strategy doesn’t do so. Also, while Quick-Change uses Buoy as its risk-off strategy, this strategy uses Cook’s proprietary bond strategy.
