Which day of the month to buy BNB at DCA?

In this idea we want to show our operation as a long term trader - further definition for the term "Investors" - in which we select - doing also fundamental analysis - assets with long term bullish Bias.

In some of our portfolios we have BNB, which we buy every month in Dollar Cost Averaging ( DCA ).

As Quant Traders and Investors, we have developed the Bias Analyzer to help us decide the day of the month when we can get a statistically advantageous price.

We notice that between the 20th and 22nd the price of BNB tends to fall and therefore today, we can buy at market whenever we want, considering that the day of is calculated at midnight UTC .

Or we can combine the BIAS information by calculating Fibonacci levels or Hosoda's 50% to find a good point.
