Downtrend since 84,797, compressing in a base · RSI 54 · price 80,729.10
Lower highs from the 84,797 swing high; 79,170-80,950 base with shallow higher lows.
The slide from the 84,797 swing high on Oct 21 put in a 79,174 swing low on Oct 24. Since then BTC has carved a 79,170-80,950 base, with a shallow higher low at 79,405 and lower highs pressing in from 80,950. ATR(14) has compressed to roughly 724 USD from 1,000+ during the drop. Price is now testing the top of that squeeze above the ema20 but still below the EMA50, as a firm USD into Wednesday's FOMC keeps rallies contained.
What it said to watch
H4 close above the 80,950 range high breaks the lower-highs sequence and exposes the fib 38.2 at 81,320, then the 81,975 lower high.
Loss of the ema20 near 80,410 and then the 79,405 higher low returns focus to the 79,174 swing low.
FOMC decision Wed 18:00 UTC and presser 18:30 UTC: a hawkish hold with USD and yields firming could resolve the compression lower. A dovish tilt would be the larger surprise.
Thu 12:30 UTC Core PCE (f/c 0.3% MoM, 3.1% YoY) is a second catalyst inside the next few bars.
Lower low at 79,174 after the 84,797 swing high; pennant of lower highs and rising lows since.
The slide from the 84,797 swing high broke below the prior 79,737 low to 79,174. Since then BTC has compressed into a pennant, with rising lows off the 79,285 range floor and lower highs capping under the 80,955 range top. Price is now pressing the pennant top near the 23.6% retracement at 80,500, holding above EMA20 but below EMA50, and EMA20 is still under EMA50. ATR(14) has eased to roughly 740 USD from the expansion during the drop, as firm US data and hawkish-hold Fed positioning keep BTC heavy as a macro risk asset into Fed week.
What it said to watch
H4 close above the 80,955 range top breaks the pennant and brings the 38.2% retracement at 81,320 and the 81,975 lower high into view
Loss of the 79,285 range floor and the 79,174 swing low would extend the lower-low sequence
Fed decision Wed 18:00 UTC and presser 18:30 UTC could materially shift this read, with Thu 12:30 UTC core PCE as the follow-through test
Lower highs since 84,797 top onto a flat base of swing lows near 79,300.
BTC has printed lower highs since the 84,797 range top. The slide has stalled into a flat cluster of swing lows around 79,300, just above the 79,174 window low, and under a falling lower-high trendline, a descending-triangle shape. ATR(14) has compressed to roughly 700 points from 1,000+ during the mid-window swings. Price sits below both EMAs with EMA20 under EMA50, as firm US data and a USD rebuilding its hawkish-hold premium into Wednesday's FOMC weigh on rate-sensitive assets.
What it said to watch
H4 close below the 79,174 window low breaks the swing lows base and extends the lower-low sequence
H4 close above the 80,730 lower high and the lower-high trendline invalidates the descending structure, with the 80,950 prior high next
Recovery toward the 50% fib at 81,985 would put price back inside the mid-window range
Fed decision and Powell presser Wed 18:00/18:30 UTC could materially shift this read; a hawkish lean is the flagged risk
Core PCE and PCE YoY Thu 12:30 UTC could extend any post-FOMC move
Lower highs since 84,797 pressing into a flat floor near 79,200-79,500.
BTCUSD has printed a sequence of lower highs since the 84,797 peak on Oct 19, from the Oct 22 high at 81,975 down to the latest lower high at 80,730. The 79,170 swing low and successive dips into 79,285-79,475 form a flat floor, a descending-triangle shape now trading on the Oct 13 low at 79,740. Price sits below both EMAs with EMA20 under EMA50, and ATR(14) has contracted to roughly 685 points from well over 1,000 earlier in the window, a compressed regime into Wednesday's Fed decision, which the digest frames as a liquidity and risk-proxy driver for BTC.
What it said to watch
H4 close below the 79,170 swing low resolves the compression lower and extends the lower-low sequence
H4 close above the 80,730 lower high breaks the descending trendline and opens the 38.2% fib at 81,320
Recovery through the Oct 22 high at 81,975 would invalidate the lower-high structure
Fed decision and statement Wed 18:00 UTC (hold at 4% expected) could materially shift this read; Durable Goods 12:30 UTC and Consumer Confidence 14:00 UTC today are earlier risk
Lower highs since 84,797 rejection; flat lows at 79,170-79,370.
Since the 84,797 rejection on Oct 21, BTC has printed a sequence of lower highs (81,975, 80,955, 80,730) and pressed into a 79,170-79,370 swing low shelf. That shelf has been tested three times, giving a descending, compressing structure below both EMAs, with EMA20 under EMA50. ATR(14) has contracted to roughly $700 from $1,000+ earlier in the month, so a breakout looks pending into Wednesday's Fed decision, where firm US data and sticky 4.7% inflation expectations frame the risk of a hawkish statement.
What it said to watch
H4 close below the 79,170 swing low confirms a lower-low and puts the 79,000 round number in focus
H4 close above the 80,730 lower high and descending trendline invalidates the compression-under-resistance read
Reclaim of the 80,955 swing high would expose the 81,975 prior high, which aligns with the fib 50% of the 84,797-79,170 drop
Fed decision and statement Wed 18:00 UTC could break the compression either way; durable goods Tue 12:30 UTC is the last major pre-Fed print

Downtrend, momentum fading into a tight base · RSI 44 · price 80,045.85
Lower highs since 84,797; compressing above 79,174 swing low.
Rejection from the 84,797 high started a sequence of lower highs, with the 81,975 lower high and a falling lower-high line capping every bounce since. For roughly four days price has been held in an 79,300–80,950 band. The 79,300 base lows have held repeatedly just above the 79,174 swing low, the range cap sits near 80,950, and price stays below both EMAs. ATR(14) has contracted to about $690 from $1,000+ during the drop. BTC is trading as a macro risk proxy into Fed week, with firm US data and sticky 4.7% inflation expectations limiting dovish hopes, so the compression looks like it is waiting on the FOMC.
What it said to watch
H4 close below the 79,174 swing low extends the lower-low sequence out of the base
H4 close above the 80,950 range cap and the lower-high line breaks the compression, with fib 38.2 at 81,320 and the 81,975 lower high next
FOMC statement Wed 18:00 UTC; a hawkish lean on inflation expectations is the main risk to the base lows
Durable Goods Tue 12:30 UTC could trigger the first expansion out of the range
