Bears Power Index works with its twin indicator, Bulls Power, to confirm trend signals from other indicators. Learn how to use it effectively in your automated trading strategies with Tradeworks.

Bears Power oscillator confirming trend signals in Tradeworks trading platform

Understanding Bears Power

Bears Power Index is a momentum oscillator that measures selling pressure in the market. In Tradeworks strategy logic, it is not a standalone entry signal. It works as a confirmation layer after another trend indicator has already created the primary buy or sell context.

Bears Power and Bulls Power are twin indicators designed to work together. While Bears Power measures selling pressure (for buy confirmation), Bulls Power measures buying pressure (for sell confirmation). This bull bear power pairing helps traders compare seller strength and buyer strength before using either oscillator as a confirmation filter in automated rules. Using both gives symmetrical confirmation logic across both trade directions.

How Bears Power Works in Automated Trading

  • Twin indicator: Bears Power is commonly used with Bulls Power for symmetrical confirmation logic
  • Buy confirmation: Bears Power confirms a buy setup when it is below zero but rising
  • Sell confirmation: Bulls Power can confirm the sell side when it is above zero but falling
  • Primary signal required: Use a trend indicator such as Moving Average, ADX, or MACD for the main signal first

Bears Power Index is often used together with its twin indicator, Bulls Power Index. It is an oscillator measuring the strength of the sellers in the market. Bears Power Index is calculated as the difference between the low and the exponential moving average for the given period (default setting is 13 periods). The Bears/Bulls Power Index indicators can be tested together with another trend indicator. If the trend indicator creates the buy context, Bears Power can be used as an added filter when it is below zero but rising.

Strategy 1: Bears Power + Moving Average Confirmation

Trend Confirmation

Bears Power strategy using Moving Average trend confirmation with oscillator below zero but rising

This strategy uses Moving Average direction as the primary trend signal and Bears Power as the buy-side confirmation filter. Bulls Power provides the mirrored sell-side confirmation.

Setup in Tradeworks:

  1. Add Moving Average with a 50-period setting
  2. Add Bears Power with the default 13-period setting
  3. Add Bulls Power for the symmetrical sell-side logic
  • Open Position Buy Signal: Strategy symbol ASK price is accepted when Moving Average trend signal is buy, Bears Power is less than 0, and Bears Power is rising
  • Open Position Sell Signal: Strategy symbol BID price is accepted when Moving Average trend signal is sell, Bulls Power is greater than 0, and Bulls Power is falling

Trade Management

  • Stop Loss Exit Signal:
    • For longs: Strategy symbol BID price is less than the recent swing low or an ATR-based distance
    • For shorts: Strategy symbol ASK price is greater than the recent swing high or an ATR-based distance
  • Take Profit Exit Signal:
    • For longs: Strategy symbol BID price is greater than the previous resistance level
    • For shorts: Strategy symbol ASK price is less than the previous support level
  • Filter: Bears Power confirms the primary trend signal; it should not open trades by itself

Strategy 2: Bears Power as RSI Oversold Filter

Mean Reversion Filter

Bears Power strategy using RSI oversold filter and Bears Power confirmation

This setup uses RSI to identify oversold context, then requires Bears Power confirmation before a long entry is accepted. The goal is to avoid treating Bears Power as the first signal.

Setup in Tradeworks:

  1. Add Relative Strength Index (RSI) with a 14-period setting
  2. Add Bears Power with the default 13-period setting
  3. Require Bears Power to remain below zero before it begins rising

Trade Management

  • Open Position Buy Signal: Strategy symbol ASK price is accepted when RSI is less than 30, Bears Power is less than 0 for 5+ periods, and Bears Power is rising
  • Open Position Sell Signal: Strategy symbol BID price can use RSI is greater than 70, Bulls Power is greater than 0 for 5+ periods, and Bulls Power is falling
  • Stop Loss Exit Signal:
    • For longs: Strategy symbol BID price is less than the recent swing low or ATR-based exit level
    • For shorts: Strategy symbol ASK price is greater than the recent swing high or ATR-based exit level
  • Take Profit Exit Signal:
    • For longs: Strategy symbol BID price is greater than prior resistance, or RSI is greater than 50
    • For shorts: Strategy symbol ASK price is less than prior support, or RSI is less than 50

Strategy 3: MACD + Bears/Bulls Power Dual Confirmation

Multiple Indicator Confirmation

Bears Power strategy using MACD crossover confirmed by Bears and Bulls Power indicators

This strategy uses MACD for the primary crossover context, then uses Bears Power or Bulls Power to confirm the trade side before the bot acts.

Setup in Tradeworks:

  1. Add Moving Average Convergence Divergence (MACD)
  2. Add Bears Power for buy-side confirmation
  3. Add Bulls Power for sell-side confirmation
  • Open Position Buy Signal: Strategy symbol ASK price is accepted when MACD crosses from below to above its signal line, Bears Power is less than 0, and Bears Power is rising
  • Open Position Sell Signal: Strategy symbol BID price is accepted when MACD crosses from above to below its signal line, Bulls Power is greater than 0, and Bulls Power is falling

Trade Management

  • Stop Loss Exit Signal: Use a volatility-based trailing stop; long exits use BID and short exits use ASK
  • Take Profit Exit Signal: Use a fixed target, previous support/resistance, or a MACD reversal condition
  • Implementation note: MACD creates the signal context; Bears/Bulls Power acts as the confirmation layer

For Bot Developers: Implementation Tips

Bears Power Logic in Tradeworks

  • Entry Signal Confirmation: Always use Bears Power with another trend indicator such as Moving Average, ADX, or MACD
  • Buy Confirmation: Bears Power is less than 0 and is rising
  • Sell Confirmation: Bulls Power is greater than 0 and is falling
  • Default Period: 13-period EMA difference from low for Bears Power

Combining with Other Indicators

  • Trend Filter: Use Moving Average to define market direction before reading Bears Power
  • Momentum Context: Use MACD for crossover timing, then Bears Power for confirmation
  • Oversold Context: Use Relative Strength Index (RSI) before applying Bears Power as a filter
  • Risk Controls: Pair entries with Average True Range (ATR)-based Stop Loss Exit Signal logic

Manageable Beginner Setup

  1. Start Simple: Use Moving Average as the primary signal and Bears Power as confirmation only
  2. Add Bulls Power: Mirror the confirmation logic for sell-side strategies
  3. Add Exits: Include Stop Loss Exit Signal and Take Profit Exit Signal rules before testing entries
  4. Avoid JPY pairs: Keep the first test set aligned with the source brief and use non-JPY examples

Frequently Asked Questions

What is the Bears Power index and how does it work? +

Bears Power Index is an oscillator that measures selling pressure in the market. It is calculated as the difference between the low price and a 13-period exponential moving average. In Tradeworks strategies, it should be used with another trend indicator for signal confirmation, not as a standalone entry signal.

Why should Bears Power be used with another trend indicator? +

Tradeworks documentation describes Bears Power as a confirmation tool. Pairing it with a trend indicator such as Moving Average or ADX gives the bot primary trend context first, then uses Bears Power to confirm whether selling pressure is weakening before a buy signal is accepted.

What does below zero but rising mean in Bears Power confirmation? +

It means the Bears Power value is less than 0 while its latest value is greater than its previous value. The oscillator is still negative, but it is moving upward, which can confirm a buy signal generated by another trend indicator.

How is Bears Power different from Bulls Power? +
