Ethereum: Best Days to Buy & Sell (Based on Data)

I ran my best trade day algorithm on Ethereum historical prices (since 2015).

Best Day to Buy: Friday (green):
(~0.6%) – ETH is usually 0.6% above the trend -> better for buying.

Best Day to Sell: Wednesday (red):
(~0.9%) – ETH is usually 0.9% above the trend -> better for selling.

The % values in the chart show the average price deviation from the short-term trend (SMA) for each weekday.

* it doesn't calculate negative (yet) because ETH has been up a lot since 2015.

***How the algorithm works:

1. Find the short term trend:
   – calculates a Simple Moving Average (SMA) over a set window (e.g., 7 days)
2. Measure deviation from the trend:
   – For each day, it compares the actual price to the SMA to find how far above or below it is.
3. Group by weekday:
   – groups those daily deviations by weekday (Mon, Tue, …)
4. Average the results:
   – find the average deviation for each weekday.

For me, running this analysis made Ethereum weekly rhythm really clear. It is fascinating to see data confirm patterns I'd noticed casually like how Fridays often felt calmer and Wednesdays more volatile.Not financial advice, just what the data says.
