According to A. Elder, 13 periods' Strength Index demonstrates dominating force on the market – bulls or bear - very well. With Force Index (13) above the middle line, bulls rule on the market, whereas FI is below the middle line, bears dominate. With FI dragging near middle line and crossing it a few times, it says about absence of market tendency. New maximum above middle line shows that ascending trend is confirmed. In this respect, a new lowest point below middle line speaks for descending tendency. When with growth or decline of price Force Index (13) starts giving decreasing extreme points – essentially, forming divergence/ convergence – it indicates that current trend loses its significance and a reversal is probable.
The Alligator indicator is a technical indicator which based on three simple moving averages with different periods and forward offset. It was developed by Bill Williams, the author of "Trading chaos" and "New dimensions in stock trading" books. He devised a trading system to predict a Forex price action on the basis of several indicators including the Alligator technical indicator.
