Seasonal Buy Signal

$$ For those following market seasonality, I believe we had a buy signal last week with the MACD crossover. Here's the chart from stockcharts:



From Sy Harding's website:

The idea is that if a rally is underway when the October 16 calendar date for seasonal entry arrives, as indicated by the MACD indicator, we will enter at that time. However, if the MACD indicator is on a sell signal when the October 16 calendar date arrives, indicating a market decline is underway, it would not make sense to enter before that decline ends, even though the best average calendar entry date has arrived. Instead, our Seasonal Timing Strategy simply waits to enter until MACD gives its next buy signal, indicating that the decline has ended.

The MACD crossed over last week. Rather dramatically.
