Traditional Japanese candlestick charts' candles frequently change from green to red (up or down), making them difficult to interpret.
Candles on the Heikin Ashi chart, on the other hand, display more consecutive colored candles, making it easier for traders to identify past price movements.
You'll notice that Heikin Ashi charts' candles tend to stay green during an uptrend and red during a downtrend.
In contrast, traditional Japanese candlesticks alternate colours even when the price is strongly moving in one direction.

Heikin Ashi (HA) and traditional Japanese candlestick charts are two popular methods for visualizing price action, each with distinct advantages. Traditional candlesticks show raw price movements over a specified time period, displaying open, close, high, and low values for each interval. This chart type is favored for its real-time accuracy and ease in spotting market reversals.

In contrast, Heikin Ashi uses a formula that smooths out price fluctuations by averaging previous candlesticks. This smoothing effect reduces market "noise," making trends clearer and helping traders stay focused on broader movements. However, because HA charts lag due to their calculation method, they’re less accurate for precise entry and exit points compared to traditional candlesticks. Overall, Heikin Ashi charts are ideal for identifying trends, while traditional candlesticks offer a more precise, real-time view.
