Vector Candle-based Channel Breakout and Custom ChoCH Strategy

Author: ChaoZhang, Date: 2024-03-29 14:45:57



This strategy combines the concept of Vector Candles with traditional Channel Breakout and Chocolate Sauce (ChoCH) pattern recognition to capture breakout movements in the market. The strategy confirms signals by comparing the closing price with the high and low of the previous candle and using volume-amplified Vector Candles, while also employing a certain number of confirmation candles to filter out noise.

Strategy Principle

  1. Calculate the average volume of a certain number of past candles and define four different colored Vector Candles (red, green, blue, purple) based on the volume amplification multiple.
  2. When the closing price is lower than the previous candle’s low and it is a red Vector Candle, identify it as a red ChoCH signal; when the closing price is higher than the previous candle’s high and it is a green Vector Candle, identify it as a green BOS signal.
  3. Within a certain number of confirmation candles, if the number of occurrences of red Vector Candles reaches the set threshold, confirm the red ChoCH signal; if the number of occurrences of green Vector Candles reaches the set threshold, confirm the green BOS signal.
  4. Open a long position when a red ChoCH signal is confirmed, and close the position when a green BOS signal is confirmed.

Strategy Advantages

  1. Combines Vector Candles with traditional Channel Breakout and ChoCH patterns, improving signal reliability.
  2. Introduces a confirmation candle mechanism to effectively filter out noise and false signals.
  3. Distinguishes signals by Vector Candle colors, making them more intuitive and easy to identify.
  4. Adjustable parameters provide flexibility and can be optimized based on different market conditions and trading styles.

Strategy Risks

  1. In a choppy market, frequent breakouts and pullbacks may lead to numerous false signals and losing trades.
  2. Improper setting of the number of confirmation candles may result in signal lag or premature entry.
  3. Relying solely on technical indicators while ignoring fundamental factors may expose the strategy to unexpected risks.
  4. The strategy does not include a stop-loss mechanism, potentially incurring significant losses during sharp market reversals.

Strategy Optimization Directions

  1. Introduce trend confirmation indicators, such as moving averages, to confirm the trend direction after a breakout signal appears, improving signal quality.
  2. For choppy markets, consider incorporating range trading strategies, such as setting long and short trigger conditions within the channel.
  3. Optimize the number of confirmation candles to find a suitable balance between effectively filtering noise and avoiding excessive lag.
  4. Set reasonable stop-loss and take-profit rules to control individual trade risk and overall drawdown.
  5. Combine with other technical indicators or market sentiment indicators to provide more basis for trading decisions.


This strategy innovatively combines Vector Candles with classic Channel Breakout and ChoCH patterns, enhancing signal reliability and recognizability through color differentiation and a confirmation candle mechanism. The strategy’s advantages lie in its clear rules, intuitive signals, and a certain degree of flexibility and optimization potential. However, the strategy also has some limitations and risks, such as subpar performance in choppy markets, insufficient grasp of market trends, and a lack of stop-loss and take-profit management. In the future, the strategy can be refined in terms of trend confirmation, range trading, parameter optimization, risk control, and other aspects to achieve more robust trading performance.
