Week of 17 July 2023: BTC slips 0.49% on volume 0.62 times its prior 12-week average
When a quiet week sees both assets fall slightly on below-average volume after a strong prior month, what does that say about direction, and what can it not say?
BTC fell from 30,232.00 to 30,083.75 (-0.49%) and ETH from 1,922.12 to 1,888.73 (-1.74%). Dollar volume ran at 0.62 times (BTC) and 0.61 times (ETH) the prior 12-week average. Funding stayed positive but tiny, averaging 0.0051% per eight hours for BTC.
What the data shows. The week was narrow and slow. BTC's range was 3.07%, from a low of 29,512.00 on Tuesday 18 July to a high of 30,417.46 on Thursday 20 July. ETH's range was 4.59%, from a high of 1,936.18 set early on Monday 17 July to a low of 1,851.18 late on Saturday 22 July, so ETH peaked at the start of the week and drifted down into the weekend while BTC did the reverse. Both assets closed in the middle third of their weekly ranges (BTC 63.1%, ETH 44.2%). Dollar volume was 5.42 billion for BTC and 2.76 billion for ETH, each about 0.6 times the prior 12-week average, and realised volatility was 25.1% and 28.4% annualised. The largest hourly move was small: -1.48% for BTC and -1.45% for ETH, both in the hour starting 14:00 UTC on Thursday 20 July. The two assets moved closely (hourly correlation 0.91), and the ETH/BTC ratio fell 1.25%, so ETH lost a little ground against BTC. Both closed below their 52-week highs: BTC by 4.82%, ETH by 11.25%.
What it does not show. Low volume does not say whether participants were waiting, absent, or simply trading small. It cannot separate buyers from sellers or say whether the week's drift was positioning or rebalancing. A -0.49% week does not establish a downtrend, and the prior four weeks were mostly up for both assets (BTC 15.65%, 0.51%, -1.49%, 0.24%). Funding was positive and small for both (BTC averaging 0.0051%, ETH 0.0049% per eight hours), which shows longs paid shorts, but not how large those positions were.
What a careful desk would check. The week's return sat at the 43rd percentile for BTC and 38th for ETH across 283 weeks, so this was an ordinary, slightly soft week by historical standards. A desk would compare its expected move with the 3.07% range rather than with the prior month's 15.65% week, and ask whether positions sized for that month still fit a 25.1% realised-volatility regime.
What would change this reading
- If volume returns towards its prior 12-week average while price holds below this week's BTC high of 30,417.46, the quiet week reads as a pause inside a larger move.
- If ETH keeps losing against BTC beyond this week's -1.25% ratio change, the pair has shifted from moving together to one asset lagging.
- If funding turns negative after averaging 0.0051% per eight hours, the small long-side carry that existed this week has disappeared.
- If a later week trades below BTC's low of 29,512.00, the drift lower becomes a directional signal rather than noise.
Terms
- realised volatility
- how much the price actually swung over a period, expressed as a yearly percentage
- percentile
- the share of past weeks with a lower value; the 43rd percentile means 43% of past 283 weeks were lower
- funding rate
- the periodic payment between long and short holders of a perpetual futures contract; positive means longs pay shorts
