Sharpe Ratio — What It Means

Formula: Avg DART Spread ÷ Std Dev of DART Spread · Baseline: DA price (your hedge / risk-free rate) · Window: Rolling 5 days × 24 hourly observations = up to 120 data points per node
A positive Sharpe means DA consistently beat RT on average relative to its volatility — locking in the DA price was the better strategy and the DA hedge outperformed. A negative Sharpe means RT consistently exceeded DA relative to volatility — RT dispatch would have captured more value than the DA commitment. Higher absolute value = stronger signal. Near zero = noisy, no clear edge either way.

● Positive — DA outperformed RT (DA commitment advantage) ● Negative — RT outperformed DA hedge (RT dispatch advantage) ● Near zero — No consistent edge, high noise Hover any Sharpe value for detail (avg, stdev, sample size)
