What are the limitations of Heikin Ashi?
Unfortunately, Heikin Ashi is not the holy grail.
Heikin Ashi definitely ain’t no Ed Sheeran song. It ain’t perfect.
Just like any other tool used for technical analysis, Heikin Ashi is useful but it does have some weaknesses or limitations.
Let’s go over what these limitations are.
Heikin Ashi candlesticks do not show true prices.
While the traditional Japanese candlesticks are derived from the actual prices, Heikin Ashi candlesticks are NOT.
Because the Heikin Ashi candlesticks are averaged, they do NOT show the exact open and close prices for a particular time period.Let’s show an actual example.
Here’s a Heikin Ashi chart of EUR/USD on the daily (1D) timeframe:
Focus on the last candlestick. A couple of things to notice:
- The candle is red. Which means the candle closed lower than it opened.
- Its open price was 1.09005.
- Its close price was 1.08531.
Now let’s look at a daily chart of EUR/USD using a traditional Japanese candlestick chart:
Focus on the last candlestick. A couple of things to notice:
- The candle is green. Which means the candle closed higher than it opened.
- This is REALITY. The EUR/USD pair actually ended up for the day. Compare this to Heikin Ashi, where it showed a red candle.
- Its open price was 1.08373.
- Its close price was 1.08706.
Let’s review what we just observed:
| Chart Type | Last Candlestick | Open Price | Close Price |
| Heikin Ashi Candlestick | Red | 1.09005 | 1.08531 |
| Traditional Candlestick | Green | 1.08373 | 1.08706 |
Do you see the difference?
Even though the “real” candle closed green, Heikin Ashi is signaling that EUR/USD is still in a downtrend.
Make sure you know what price you’re looking at.
Since you can’t see the actual open and close prices, some traders prefer to use a Heikin Ashi chart as more of an INDICATOR rather than a price chart itself.
Heikin Ashi charts obscure actual price information.
This limitation is related to the first one.
The closing price is considered important for many traders, but the actual closing price is NOT displayed on a Heikin Ashi candlestick.
As a review, here’s how the Close price is calculated:
Close = (Open+High+Low+Close) / 4
You only see the averaged closing price.
Make sure you’re aware of the actual closing price, and not just the averaged value.
This can be done easily by switching back to a regular Japanese candlestick chart.
Heikin Ashi charts may not be responsive enough for day traders or scalpers.
Since Heikin Ashi candlestick requires price information from two periods, a trade setup takes longer to develop.
This isn’t really an issue for longer-term traders, like swing traders or position traders, who have more time to let their trades develop.But it might be an issue for shorter-term traders like day traders and scalpers.
For example, scalpers need to exploit quick price moves so they may find that Heikin Ashi charts are not responsive enough for their type of trading.
