The original weekend dip strategy refers to when there is a downtrend is occurring. We are not in a downtrend.
The weekend dip strategy said that: "On Wednesday evening (west)/Thursday morning (east) if the 7-day high for the exchange rate is lower then the 7-day high from the previous week, then more likely than not, a weekend dip will result and gains of three to five percent are likely. So the recommended practice was to sell at that time, and buy those bitcoins back over the weekend when the selloff starts to reverse."
The weekend dip indicator hasn't flashed green since May. That doesn't mean there haven't been dips during the weekend, it just means they original strategy didn't suggest to sell mid-week and buy back over the weekend. Now there appears to be another pattern where buying on Saturday and selling on Tuesday or so, and do that week after week, seems to be a winning strategy. So there isn't necessarily a dip occurring over the weekend, but that a rally happens early in the week.
There is always a battle between greed and fear and the weekend dips were oftentimes where fear had the upper hand. Ever since cash deposit methods have been available even on the weekends now, a weekend decline just doesn't snowball into 10%+ selloffs anymore like they used to.
