Force index is simply the day's price change multiplied by its volume, smoothed: it is negative while sellers have both direction and size, and it crosses zero when that stops being true. Alexander Elder designed the zero cross as a pullback entry inside an uptrend, which is what the 50-day condition restores this scan to.
