BMI triggers a rebalance when the 10 Day Simple Moving Average (10 SMA) of the Bitcoin/USD ratio crosses the 50 Day Simple Moving Average (50 SMA) indicating a trend reversal. If the 10 SMA crosses and stays below the 50 SMA, BMI rebalances all Bitcoin tokens into USD to reduce further underperformance in the downtrend. If the 10 SMA of Bitcoin crosses and stays above the 50 Day SMA, BMI rebalances back into Bitcoin to capture the upside in the uptrend.
