Upstox Glitch: Stock Prices Skyrocket Incorrectly

Upstox users reported widespread technical malfunctions on Tuesday morning, April 28, 2026. The issues began shortly after the market opened, with numerous complaints detailing incorrect stock prices, erroneous percentage gains, and portfolio data failing to update. These discrepancies caused considerable concern among traders relying on the platform for real-time information.

The core problem seems to stem from the app's calculation of daily price changes. Instead of resetting to the previous day's closing price, the system appears to have carried forward earlier movements. This led to inflated or misleading figures for gains and losses, suggesting a critical backend issue with the price reference updates.

As of the time of writing, Upstox had not released an official statement addressing the reported problems. The platform remained accessible, but the displayed data was deemed unreliable for making informed trading decisions. Investors were strongly advised to cross-reference stock prices with official sources like the NSE or BSE before executing any trades.

Users experiencing these data inconsistencies were encouraged to submit support requests through the app and maintain records of any incorrect information displayed. This situation is ongoing and further updates will be provided as more details become available.
