According to the source, BTC is down 6% month-to-date in October with 12 days remaining, putting a premium on flow- and positioning-confirmation over directional guesses for the rest of the month (source: public X post dated Oct 18, 2025). Monitor net spot Bitcoin ETF inflows/outflows each US session; sustained net inflows tend to support intraday bid and reduce drawdown persistence, while net outflows often coincide with weaker price action (source: Farside Investors US spot Bitcoin ETF flow tracker; source: Bloomberg ETF flow summaries). Track perpetual funding rates and basis alongside open interest; persistent negative funding with rising open interest indicates aggressive short buildup and raises short-squeeze risk if flows flip, favoring fade-the-break tactics near obvious lows (source: Coinalyze funding and open interest data; source: Glassnode futures and derivatives metrics). Watch options open interest concentration at round-number strikes into weekly and month-end expiries; heavy call gamma above spot can cap rallies, while put gamma clusters below spot can accelerate selloffs if breached (source: Deribit options OI and expiries; source: Laevitas options gamma analytics). Frame risk using the 100–200 day moving averages and the monthly open/close as dynamic support/resistance; violations often precede liquidity grabs before mean reversion in range-bound environments (source: TradingView BTCUSD moving averages; source: CMT Association technical analysis references).
