Bitcoin climbed more than 1% on October 4, putting a recurring weekly pattern back in focus. Over the past month, the cryptocurrency's Sunday moves have repeatedly reversed at the start of the week, according to market analyst Ali Charts. At the same time, a TD Sequential sell signal has appeared on the four-hour charts of Bitcoin, Ethereum, and Solana — a setup that, in prior instances, was followed by corrections. Together, these readings point to a possible pullback when markets open on Monday, according to the analyst.

'Sunday Pump, Monday Dump' Pattern Draws Attention

Ali Charts raised the topic in a six-part thread on X published on October 4, 2026. The opening post framed the idea directly:

SUNDAY PUMP = MONDAY DUMP 1/6 — Ali Charts (@alicharts) October 4, 2026

In the second post, the analyst said Bitcoin's Sunday moves have often reversed on Monday over the past month. Sunday rallies were followed by pullbacks, while Sunday declines were followed by rebounds. According to Ali Charts, the same reversal appeared in both directions.

Bitcoin was up more than 1% on Sunday as of the time of publication, trading at $85,845. The analyst said the pattern is back in focus as a result. The opening post had recorded 3,604 views at that point, and the follow-up posts appeared minutes after the first. Cryptocurrency markets never close for the weekend, so Sunday trading flows straight into the Monday session rather than pausing at a Friday close as traditional equity markets do.

TD Sequential Flashes Sell Signal on Bitcoin

The third post added a technical warning to the calendar pattern. According to Ali Charts, the TD Sequential indicator — a timing tool developed by market technician Tom DeMark and widely used to identify potential turning points in price trends — has flashed a sell signal on Bitcoin's four-hour chart. The signal appeared while Bitcoin traded higher on the day. In its standard setup phase, the indicator completes a sell count after nine consecutive bars each close above their counterparts from four bars earlier — a sequence spanning about 36 hours on a four-hour chart.

The analyst noted that each of the last four similar signals was followed by a price correction, although the size of those four corrections was not listed. Based on that record, the thread pointed to another Monday dump. In the analyst's view, the sell signal and the "Sunday pump, Monday dump" pattern lead to the same suggested outcome: a possible pullback at the start of the week.

Ethereum and Solana Show Matching Signals

The fourth post covered Ethereum. The asset shows the same TD Sequential sell signal on its four-hour chart, and its last two signals were followed by declines of 5.40% and 3.31%, respectively. The analyst cited those two earlier declines as the reference points for Ethereum.

Solana was addressed in the fifth post. The asset has also flashed a four-hour TD Sequential sell signal, and its last three comparable signals preceded corrections of 2.44%, 5.76%, and 5.30%. Ali Charts used these readings as a historical reference for the current setup. Bitcoin, Ethereum, and Solana all rank among the largest cryptocurrencies by market value, so matching four-hour readings across the three extend the setup beyond any single asset's chart.

The final post combined all of the data points, citing the Sunday pump, a recent run of Monday dumps, and sell signals across BTC, ETH, and SOL. In earlier cases, similar signals across the three assets were each followed by declines, according to the data cited in the thread. According to Ali Charts, these factors point to a possible pullback. The "Sunday pump, Monday dump" setup therefore rests on both calendar behavior and chart signals. The thread ended with that post, and no further posts followed. With the thread complete, the next reference point is the Monday session itself — the window the analyst's timeline marks for whether the past month's pattern repeats or breaks.
