TradingView Incorrectly Showed Bitcoin Dominance Falling to 24%

On November 9, 2026, TradingView users noticed a sharp decline in Bitcoin dominance (BTC D) from approximately 60% to 24.12%. However, the change was due to an anomaly in the platform's calculation data, not an actual reduction in BTC's market share.

At the same time, the aggregated cryptocurrency capitalization indicator TOTAL on TradingView exceeded $6 trillion. This figure significantly differed from data provided by other market aggregators. According to CoinMarketCap at the time of the incident, Bitcoin dominance remained around 60.3%. Thus, there was no basis to believe that BTC had indeed lost more than half of its market share in a short period.

Why TradingView Showed a Drop in BTC D

Bitcoin dominance reflects the ratio of BTC's market capitalization to the total cryptocurrency capitalization. This indicator is expressed as a percentage and helps assess Bitcoin's relative position among other digital assets.

According to TradingView documentation, the TOTAL index is calculated based on the capitalization of the 125 largest cryptocurrencies. To determine BTC D, Bitcoin's capitalization is divided by the TOTAL value, and the result is multiplied by 100%.

Therefore, a sharp increase in total capitalization in the platform's calculations automatically leads to a decrease in BTC's share, even if Bitcoin's own capitalization has not undergone a comparable change. This was the situation observed on November 9. The TOTAL value anomalously rose above $6 trillion, causing BTC D to temporarily drop to 24.12%.

TradingView's help center states that sharp jumps in aggregated indicators can occur when the composition of the largest cryptocurrencies included in the calculation changes. However, the company did not confirm that this was the cause of the incident in question.

Do Other Indicators Confirm the Start of Altseason

The unusual dynamics of BTC D sparked discussions among social media users. Some market participants suggested that the sharp decline in Bitcoin dominance might indicate the approach of an altcoin season.

However, other indicators did not confirm such a scenario.

According to CoinMarketCap at the time of publication, the Altcoin Season Index was at 40 out of 100. A similar indicator from CoinGlass was at 44 points. CoinMarketCap's methodology involves comparing the performance of major altcoins with Bitcoin over the previous 90 days. An altcoin season is recorded when at least 75% of the cryptocurrencies considered outperform BTC by this measure.

A value of 40 means that most of the assets considered underperformed Bitcoin in terms of returns for the reporting period. Moreover, a decline in BTC dominance does not guarantee altcoin growth. The indicator can decrease in situations where Bitcoin depreciates faster than other cryptocurrencies.

When Will TradingView Fix the Error

At the time of the anomaly reports, TradingView had not published a separate explanation of its causes or provided a timeline for correction.

The platform's documentation notes that significant jumps in aggregated capitalization indicators can be manually corrected after they are identified. However, it is unknown whether such a correction was required for the data from November 9 and how long the erroneous value remained available on the charts.

The incident highlights why it is important to compare information from several independent sources when there are sharp changes in calculated market indicators. To assess Bitcoin dominance and altcoin dynamics, one should consider not only BTC D but also actual quotes, market capitalization, and the relative performance of digital assets.
