The Coulter Efficiency Ratio (CER) is a technical indicator that is widely used by algorithmic traders to assess the efficiency of a trading strategy. Developed by John Coulter, a renowned financial analyst and trader, the CER provides valuable insights into the performance and effectiveness of trading algorithms.

## Definition and Formula

The Coulter Efficiency Ratio is a ratio-based indicator that measures the ratio of the average profit per trade to the average loss per trade. It is calculated using the following formula:

CER = (Average Profit per Trade) / (Average Loss per Trade)

The resulting value of the CER provides traders with an indication of the profitability and risk-reward profile of their trading strategy. A higher CER indicates a more efficient and profitable strategy, while a lower CER suggests the need for improvements or adjustments.

## How to Use the Coulter Efficiency Ratio

Algorithmic traders can use the Coulter Efficiency Ratio in various ways to enhance their trading strategies:

1. Assessing Strategy Performance: By calculating the CER, traders can evaluate the effectiveness of their trading strategy and identify areas for improvement. A higher CER suggests that the strategy is generating more profits compared to losses, indicating a successful approach.

2. Comparing Strategies: Traders can use the CER to compare the efficiency of different trading strategies. By calculating the CER for each strategy, they can determine which one is more profitable and suitable for their investment goals.

3. Combining with Other Indicators: The CER can be used in conjunction with other technical indicators to validate trading signals. By considering the CER alongside other indicators such as moving averages or relative strength index (RSI), traders can make more informed trading decisions.

## Signals and Interpretation

When analyzing the Coulter Efficiency Ratio, traders should consider the following signals:

• High CER: A CER above 1 indicates that the average profit per trade is higher than the average loss per trade. This suggests a profitable trading strategy with a favorable risk-reward ratio.

• Low CER: A CER below 1 indicates that the average loss per trade is higher than the average profit per trade. This may indicate a less efficient or unprofitable trading strategy.
