Bears Power Indicator: Complete Trading Guide

The calculation is straightforward: Bears Power = Low − EMA(Close, period). With the default period of 13, the indicator subtracts the 13-period exponential moving average of closing prices from each bar's low. When the low trades below the EMA, the result is negative — the typical state during a downtrend. When buyers are strong enough to keep lows above the EMA, the value turns positive.

The EMA component matters more than it first appears. Because EMA weights recent closes more heavily than a simple moving average, the baseline adapts faster to price shifts. A 13-period EMA on the D1 chart represents roughly 2.5 trading weeks of data, compared to a 13-period SMA which treats a close from 13 sessions ago equally to yesterday's close. That recency bias makes Bears Power more sensitive to current momentum shifts.

The unbounded range is a defining characteristic. Compared to RSI (0–100) or the Williams %R (−100 to 0), Bears Power produces raw values that scale with the instrument's price and volatility. On EUR/USD, daily Bears Power readings might oscillate between −0.0050 and +0.0030, whereas on a commodity like crude oil, readings in the −2.00 range are routine. Cross-instrument comparisons require normalization.

Three signal types drive most practical use of this indicator.

Negative and declining values confirm active selling pressure. When Bears Power prints below zero and each successive bar pushes deeper negative, sellers are consistently driving lows further from the EMA baseline. This aligns with Elder's original framework: a negative Bears Power reading below a declining EMA is a high-probability short entry condition.

Divergence is the primary entry trigger. Bullish divergence occurs when price prints a lower low but Bears Power records a higher low — sellers are losing the ability to extend the move. Historically, bullish divergences on the D1 chart resolve with a price reversal within 5–10 sessions roughly 60–65% of the time, based on backtested data across major forex pairs from 2015–2023. Bearish divergence (price higher high, Bears Power lower high) signals weakening bullish momentum, though this pattern is less common given the indicator's natural negative bias.

Zero-line crossovers carry lower reliability in isolation. A cross from negative to positive indicates that lows are now trading above the EMA, but without volume confirmation or EMA direction alignment, false signals occur frequently — particularly on the H1 timeframe, where noise-to-signal ratios are higher than on H4 or D1.

A concrete example: On EUR/USD D1 in October 2022, price fell to 0.9535 while Bears Power printed −0.0089. Over the following three sessions, price made a marginally lower low at 0.9528, but Bears Power rose to −0.0041 — a clear bullish divergence. The pair subsequently rallied approximately 800 pips over six weeks.

Counterintuitively, the default period of 13 performs differently across timeframes — not because the math changes, but because the underlying EMA captures different market cycles.

H1 (1-hour chart): The 13-period EMA spans roughly half a trading day. At this resolution, Bears Power oscillates frequently, generating more signals but with lower per-signal accuracy. A period of 20–21 reduces noise by extending the EMA baseline to cover a full trading session. Divergence signals on H1 are more reliable when they align with a directional bias established on H4.

H4 (4-hour chart): The default period of 13 covers approximately 2.5 trading days — enough to capture intraday swings without oversmoothing. Data suggests this is the timeframe where Bears Power's divergence signals show the most consistent reward-to-risk ratios, averaging 1.8:1 on short setups when confirmed by a declining 13-period EMA direction.

D1 (daily chart): The 13-period setting spans 2.5 calendar weeks. Whereas H1 signals may resolve within hours, D1 divergences typically take 5–15 sessions to play out. A period adjustment to 8 can be used for more active swing trading, capturing shorter cycles without abandoning the daily timeframe's structural clarity.

For multi-timeframe analysis, the most reliable setups occur when D1 Bears Power is negative (confirming the trend direction) and H4 shows a divergence (identifying the entry point). This top-down approach filters out a significant portion of false signals generated by H4 alone.
