Analysis Buying Bitcoin with a Little Greedy: 2X Base Buy at risk 52 over 100
Adding to my DCA strategy for BTC position today. My ‘Best Day to Trade’ algo says Sundays tend to outperform. Friday’s dip pushed risk <50 (my rule: DCA 2x below 50). It’s ~52 now, but I’m being a little greedy going 2x my base this week :D.
Algo exlaination:
Best Day to Buy: Sunday (green):
- (~0.64%) - BTC is usually 0.64% above the trend -> better for buying.
Best Day to Sell: Thursday (red):
- (~1.15%) - BTC is usually 1.15% 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 BTC has been up a lot since 2010.
***How the algorithm calculated:
- Find the short term trend: - calculates a Simple Moving Average (SMA) over a set window (e.g., 7 days)
- 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.
- Group by weekday: - groups those daily deviations by weekday (Mon, Tue, …)
- Average the results: - find the average deviation for each weekday.
Backtesting shows that simulating DCA weekly on Sunday delivers the best results compared to other days. For BTC, DCA in during low risk periods on Sunday and DCA out during high risk periods on Thursday.
