21:04 UTC
Uptrend, stalling under 1.4000 · RSI 72 · price 1.39881
Higher highs and higher lows; tight consolidation at range top.
Higher-low structure has been intact since the 1.3759 swing low, and the hawkish FOMC 25bp hike plus the widened US-Canada front-end spread powered a multi-day extension that cleared the 1.3950 pivot in a single 75-pip impulse bar — well above the ~20 pip ATR(14) regime. Price has since gone flat between 1.3973 and the 1.4001 window high, holding above both EMA20 and EMA50, with the EMAs stacked bullish since the mid-window cross. Momentum is stretched (RSI in the low 70s) and the 1.4000 psychological handle is capping for a fourth bar, so the read is trend continuation into resistance rather than fresh expansion; a sustained close above 1.4001 would open the 1.4050 round number.
Support: 1.3973, 1.3950, 1.3910
Resistance: 1.4001, 1.4050
What it said to watch
Four bars capped by the 1.4001 window high — area to monitor for rejection or a clean break
Loss of the 1.3973 range low would be the first lower-low of this leg and shift focus back to the 1.3950 ema20 pivot
A break back under 1.3910 (ema50) would invalidate the higher-low structure
BoC Macklem speaking Mon 15:00 UTC is the first CAD-side catalyst after seven holds and could materially shift this read
Higher highs and higher lows since the 1.3759 low; breakout above the 1.3920-1.3944 shelf holding.
Sequential higher lows since the 1.3886 swing low have carried into a clean break of the 1.3920-1.3944 shelf, with the impulse bar that cleared the prior high at 1.3944 driven by the hawkish Fed hike set against a BoC that has now stood pat for seven meetings. Price has since stalled in a tight band under the 1.4000 round number, with the window high at 1.4001 capping four consecutive bars while EMA20 sits above EMA50 and both track below spot. ATR(14) near 21 pips is expanded versus the mid-window compression, so the trend leg is still working rather than coiling, but RSI in the mid-70s shows the move is stretched.
Support: 1.3944, 1.3900, 1.3886
Resistance: 1.4001, 1.4150
What it said to watch
Sustained H4 close above 1.4001 would open the 1.4000-1.4150 next band
Repeated wicks into 1.4000 without a close through it keeps the round number as the rejection point
Loss of 1.3944 on a closing basis breaks the higher-low sequence; 1.3900 is the next reference
BoC's Macklem Monday 15:00 UTC and US Industrial Production are the near-term inputs that could reset this structure
15:21 UTC
Uptrend, extended into round number · RSI 73 · price 1.39981
Higher highs and higher lows since the 1.3759 low; breakout above the 1.3935-1.3944 band now capped at 1.4000.
USDCAD has built an unbroken sequence of higher lows since the 1.3759 swing low, clearing the 50d cluster near 1.3900 and then the 1.3935-1.3944 prior high band on the hawkish FOMC hike against a parked BoC, which widened the front-end spread. The last four bars are compressed in a 1.3980-1.4001 shelf directly under the 1.4000 round number, with a single 75-pip expansion bar doing most of the work and ATR(14) back near 21 pips. RSI above 70 shows momentum stretched rather than fading, and price sits well clear of both EMA20 and EMA50.
Support: 1.3944, 1.3900, 1.3860
Resistance: 1.4001, 1.4050
What it said to watch
Acceptance above the 1.4000 round number would extend the breakout toward the 1.4050 next figure
A close back under the 1.3944 prior high would turn the breakout into a false break and re-expose the 1.3900 50d cluster
Loss of 1.3860 swing low would end the higher-low sequence
BoC Macklem Monday 15:00 UTC is the nearest CAD-specific catalyst and the main squeeze risk to this read
13:03 UTC
Uptrend, extended but intact · RSI 74 · price 1.39981
Higher highs and higher lows since the 1.3759 swing low; breakout through 1.3944 now consolidating under 1.4000.
USDCAD has carved a clean higher-high, higher-low sequence off the 1.3759 swing low, and the hawkish FOMC hike that widened the Fed-BoC spread to 1.625 produced the 75-pip impulse bar that cleared the 1.3944 prior high. Price is now pressing the 1.4000 psych figure with the last four bars holding a tight 1.3981-1.4001 band, and both EMA20 (~1.3940) and EMA50 sit below spot. ATR(14) near 21 pips is expanding versus the mid-window grind, consistent with trend extension rather than compression, though RSI above 74 shows the move is stretched after six sessions of gains.
Support: 1.3940, 1.3900, 1.3864
Resistance: 1.4001, 1.4150
What it said to watch
Sustained H4 closes above the 1.4000 psych figure would open the 1.4000-1.4150 upper band
Repeated rejection at 1.4001 with a close back below 1.3940 (ema20) would negate the breakout read
Loss of 1.3900 psych would break the rising higher-lows sequence off 1.3759
US jobless claims and Philly Fed today, plus BoC Macklem on Monday, are the events most able to reshape this structure
13:03 UTC
Uptrend, extended into round number · RSI 72 · price 1.39981
Higher highs and higher lows since the 1.3759 swing low; breakout above the 1.3944 shelf.
Price has built a clean sequence of higher highs and higher lows since the 1.3759 swing low, and the impulse bar off 1.3920 cleared the 1.3944 shelf that had capped the advance for three sessions — the move coinciding with the hawkish Fed hike that widened the Fed-BoC spread to 1.625 while the BoC stays on hold. EMA20 sits above EMA50 with price above both, and the last four bars have compressed into a 20-pip band directly under the 1.4000 psych level, printing a range high at 1.4001. ATR(14) near 21 pips is elevated versus the mid-window grind, so the expansion phase is still live rather than exhausted.
Support: 1.3920, 1.3890, 1.3759
Resistance: 1.4001, 1.4000, 1.4150
What it said to watch
An H4 close above 1.4000 would extend the breakout toward the 1.4150 prior band
Repeated rejection at the 1.4001 range high with a close back under 1.3920 would invalidate the breakout read
Loss of 1.3890 (ema50) would break the higher-low sequence
US claims and Philly Fed today, then BoC's Macklem Monday, are the scheduled events capable of reshaping this structure
11:50 UTC
Uptrend, extending after breakout · RSI 72 · price 1.39961
Higher highs and higher lows since the 1.3759 base.
Higher highs and higher lows have been in place since the 1.3759 base, and the impulse bar through the prior high at 1.3944 resolved several days of compression before stalling just under the week high at 1.3998. The leg carries the USD safe-haven bid tied to Hormuz headlines, which has so far overridden the CAD strength from the 75.1K jobs beat. ATR(14) near 20 pips has expanded on the breakout bar, and price is holding above EMA20 with EMA50 trailing near 1.3885.
Support: 1.3944, 1.3920, 1.3885
Resistance: 1.3998, 1.4050
What it said to watch
A close back below the 1.3944 prior high would frame the move as a false break
Loss of the 1.3920 swing low ends the higher-low sequence
Acceptance above the 1.3998 week high opens the path toward the 1.4050 round number
US CPI is the next macro catalyst and could materially shift this read
RSI above 70 into resistance — area to watch for rejection or continuation
11:50 UTC
Uptrend, extending after breakout · RSI 75 · price 1.39961
Higher highs and higher lows since the 1.3759 low; range top cleared.
Price has built a sequence of higher lows off the 1.3759 low and, on the last expansion bar, cleared the 1.3944 prior swing high that capped the pair twice earlier in the window — a clean breakout with ATR(14) widening to roughly 24 pips as that bar printed a 75-pip range. The last three bars have gone flat between 1.3985 and the 1.3998 window high, holding just under the 1.4000 psych handle, with price above both EMA20 (~1.3940) and EMA50. The macro read frames 1.40 as the balance point between a USD safe-haven bid and firm-oil CAD support, and RSI near 74 shows the move is stretched rather than fresh.
Support: 1.3944, 1.3920, 1.3866
Resistance: 1.3998, 1.4000
What it said to watch
Sustained trade above 1.4000 psych would extend the breakout leg
An H4 close back below the 1.3944 breakout lvl would negate the breakout read
Loss of the 1.3920 impulse low returns price inside the prior range toward 1.3866
US inflation data is the named swing factor for USD and could materially shift this read
