Volatility-Targeted Crypto Allocation with Regime Filter
same coins, half the drawdown
Buy-and-hold BTC carries brutal drawdowns; scaling exposure inversely to realized volatility and cutting risk when a long-term regime filter (e.g. 200-day MA) is negative historically lifts risk-adjusted returns versus static holding. This is a volatility-family overlay distinct from the pure trend idea (#1) — it targets a constant risk budget rather than a directional breakout.
Why it's relevant now
BTC now trades as a correlated risk asset (not a hedge) with elevated realized vol (~49% BTC, higher for alts) into a hawkish Fed and lumpy ETF flows — precisely the regime where vol targeting and a defensive filter earn their keep.
Universe
BTC-USD and ETH-USD (yfinance daily); cash/flat as the risk-off state.
How it works
Size each asset to a target annualized volatility using trailing 20–30 day realized vol; scale total exposure to zero when price is below its 200-day MA; rebalance daily/weekly.
Expected performance
Research-derived Sharpe estimate: 0.6–1.1. static BTC ~0.8–1.0; vol targeting + regime filter typically adds 0.2–0.5 gross, discounted for turnover costs).
Backtest this idea with SignalChain
This is a research lead — not a finished backtest. SignalChain takes an idea like this and runs the whole pipeline inside Claude Code: it researches the concept against academic and practitioner sources, sets benchmarks, writes and lints a VectorBT backtest, runs it, and grades the result PASS/FAIL. One command:
/signalchain Volatility-targeted long-only BTC-USD and ETH-USD: size each to constant target volatility using 20-day realized vol, go to cash when price below its 200-day moving average.
