Money Flow Index is a volume-weighted RSI that incorporates both price and volume data, providing a more complete picture of buying and selling pressure than RSI alone. MFI divergence carries extra weight because it reflects real capital commitment, making it invaluable for crypto and stock traders. Pair MFI readings with your trading strategies and always confirm signals with price structure. Explore our complete indicator guide library to find complementary oscillators and volume tools.
MFI uses Typical Price × Volume to calculate positive and negative money flow over 14 periods. Money Ratio = Positive Flow / Negative Flow. MFI = 100 − [100 / (1 + Money Ratio)]. Scale is 0-100.
The Gator Oscillator is a histogram companion to the <a href="/academy/indicators/alligator" class="text-primary hover:underline">Alligator</a> indicator, visualising the degree of convergence or divergence between the Alligator's three smoothed moving averages. It makes it easier to see when the Alligator is sleeping, awakening, eating, or sated — key phases in Bill Williams' trading system. Use both indicators together on <a href="/tools/platforms/tradingview" class="text-primary hover:underline">TradingView</a> and pair with the <a href="/academy/indicators/awesome-oscillator" class="text-primary hover:underline">Awesome Oscillator</a> for the complete Williams toolkit.
Williams %R is a momentum oscillator that measures where the current close sits relative to the highest high over a lookback period — essentially the inverse of the <a href="/academy/indicators/stochastic-oscillator" class="text-primary hover:underline">Stochastic Oscillator</a>, excelling at identifying reversal zones. It is most effective in range-bound <a href="/market/forex" class="text-primary hover:underline">forex</a> and <a href="/market/stocks" class="text-primary hover:underline">stock</a> markets where clear support and resistance levels exist. Combine %R with trend-following <a href="/strategies" class="text-primary hover:underline">strategies</a> to take only high-probability entries in the direction of the dominant trend.
Bears Power and Bulls Power — collectively known as the Elder-Ray Index — measure the strength of buyers and sellers relative to a 13-period <a href="/academy/indicators/exponential-moving-average" class="text-primary hover:underline">EMA</a>, helping traders assess the balance of power at any given moment. Developed by Alexander Elder, this system works best when the EMA is trending and one of the power readings dips to near zero in the trend direction. Combine it with the <a href="/academy/indicators/force-index" class="text-primary hover:underline">Force Index</a> for the full Elder trading system across <a href="/market/stocks" class="text-primary hover:underline">stocks</a> and <a href="/market/forex" class="text-primary hover:underline">forex</a>.
Rate of Change measures the percentage change in price over a specified period — the simplest momentum indicator that provides a clear picture of whether price acceleration is increasing or decreasing. ROC works across <a href="/market/stocks" class="text-primary hover:underline">stocks</a>, <a href="/market/crypto" class="text-primary hover:underline">crypto</a>, and <a href="/market/forex" class="text-primary hover:underline">forex</a>, making it a versatile addition to any <a href="/strategies" class="text-primary hover:underline">trading strategy</a>. Use ROC divergence as an early warning signal alongside tools from our <a href="/academy/indicators" class="text-primary hover:underline">indicator guide library</a> for multi-factor confirmation before entering a trade.
