DeltaStats (Anchored)
Benchmark price, volatility, and true range against your anchor period—instantly.

Metrics:
• Net Change
– Compares current close to the opening price of the chosen anchor period for % and log returns
– Normalized (PoP) Change = (net move ÷ √span) ÷ weighted average of per-bar absolute moves over the normalization span
• Standard Deviation
– Calculates SD over the anchor period and displays: % of mean, log % of mean
– Normalized (PoP) SD = (current period SD − prior period SD) ÷ weighted average of per-period RMS deviations over the normalization span
• Average True Range
– Calculates ATR over the anchor period and displays: TR/TrueMid % (avg), TR/TrueMid log % (avg)
– Normalized (PoP) ATR = (current period ATR − prior period ATR) ÷ weighted average of per-bar true ranges over the normalization span

Toggle each metric between
1. % of Baseline
2. Log % of Baseline
3. Normalized (PoP—period-over-period)

Underlying calculations:
• Net Change
– % vs baseline = (close ÷ anchorOpen − 1) × 100
– Log % vs baseline = log(close ÷ anchorOpen) × 100
– Normalized (PoP) = (Δ ÷ √span) ÷ weighted average of |Δ one-bar| over norm span

• Standard Deviation
– % of mean = SD(period) ÷ SMA(close, period) × 100
– Log % of mean = log(SD(period) ÷ SMA(close, period) + 1) × 100
– Normalized (PoP) = (SD(period) − SD(prior period)) ÷ weighted average of per-period RMS deviations over norm span

• Average True Range
– % vs TrueMid = SMA(TR ÷ TrueMid, period) × 100
– Log % vs TrueMid = SMA(log(TR ÷ TrueMid + 1), period) × 100
– Normalized (PoP) = (ATR(period) − ATR(prior period)) ÷ weighted average of one-bar TR over norm span
