Bulls Power Indicator: Complete Trading Guide

The formula is almost insultingly simple: Bulls Power = High − EMA(Close, 13). That's it. Every bar, the indicator subtracts the 13-period exponential moving average of closing prices from the session high. When buyers are dominant, the high extends well above the EMA, producing a large positive value. When momentum fades, the histogram bar shrinks toward zero. Negative readings — where the high closes below the EMA — signal that buyers cannot even reach average territory.

The unbounded range matters here. Unlike RSI or Stochastic, Bulls Power has no ceiling. A EUR/USD daily bar in a strong trend might post a reading of 0.0080 (80 pips above EMA), while a compressed consolidation period might see values under 0.0010. This scaling makes cross-asset comparisons awkward but gives you a raw, unfiltered view of buying pressure on any single instrument.

The EMA acts as the gravitational center. Price is always being pulled back toward it, so the distance between the high and the EMA directly quantifies how hard buyers are fighting that gravity. Larger bars = more effort. Shrinking bars = effort fading. The zero line represents equilibrium — neither side has an edge.

Three setups generate the most reliable entries when using Bulls Power.

Signal 1 — Trend Confirmation: When Bulls Power stays consistently positive across 10 or more consecutive bars, the underlying trend has genuine buying pressure behind it. Enter longs on pullbacks to the EMA, not at the peak of the histogram. The histogram height tells you momentum; the EMA tells you price.

Signal 2 — Zero-Line Crosses: A cross from negative to positive territory signals a potential trend reversal. The most reliable version occurs after a prolonged negative period (minimum 5-8 bars below zero), followed by a single bar that closes above zero while price simultaneously breaks above the EMA. This confluence filters out roughly 60% of false signals compared to using the cross alone.

Signal 3 — Bullish Divergence (the highest-probability setup): Price prints a lower low while Bulls Power prints a higher low. This divergence, particularly visible on H4 and D1 charts, signals exhausted selling pressure even as price continues declining. In practice, pair this with a 13-period EMA slope change — if the EMA starts flattening while divergence forms, the reversal probability increases substantially.

For sell signals, Elder's original framework pairs Bulls Power with Bears Power (Bears Power = Low − EMA). A sell setup triggers when Bulls Power is positive but declining while Bears Power is negative and falling deeper — meaning buyers are losing grip while sellers accelerate. Using Bulls Power in isolation for shorts is a common mistake; it measures bullish pressure, not bearish conviction.

Pulsar Terminal's one-click SL/TP tools let you place stops directly below the EMA level that Bulls Power is referencing, keeping your risk anchored to the same price structure generating the signal.

The default period of 13 was calibrated for daily charts by Elder. Applying it unchanged across all timeframes produces inconsistent results.

On H1, dropping to period 8 makes the indicator more reactive, useful for catching intraday momentum bursts during London or New York open. The tradeoff is more noise — expect roughly 30% more zero-line crossovers that don't follow through.

H4 is where the default 13 period earns its reputation. The 2022–2023 USD strength cycle demonstrated this clearly: Bulls Power on the DXY daily chart stayed negative for 47 consecutive bars between February and October 2023, giving position traders a clean framework to avoid long dollar entries during that entire window.

On D1 with a period of 21, the indicator smooths significantly. Divergences become rarer but more meaningful — when one appears on a weekly or daily chart with period 21, it typically precedes moves of 150–400 pips on major pairs. The cost is lag; entries come later, but false signals drop considerably.
