TradingView has replaced its automatic stock split detection system with an explicit transaction-based approach, giving users direct control over how corporate actions are applied to their portfolios. The platform now treats stock splits as their own transaction type, verified by external data providers rather than inferred from price behavior, marking a significant shift in how the portfolio management tool handles one of the most common corporate actions affecting holdings.
- Implementation Method: Split suggestions appear in Portfolio Tips with symbol, date, and ratio pre-filled from provider data
- User Control: Investors can accept, defer, or manually edit split transactions; suggestions remain visible until acted upon
- Data Integration: CSV import and export supported for split transactions using existing file format
- Portfolio Impact: Existing positions with past splits may require manual acceptance via Portfolio Tips to reflect adjusted metrics
The previous system relied on heuristics to detect splits by monitoring for unusual price deviations from market rates. This approach frequently created problems: uncommon split ratios such as 15:14 or 101:100 were frequently misinterpreted, adjustments were applied indiscriminately across all transactions for a symbol without selective control, and changes occurred silently with no audit trail. Users had no visibility into what adjustments the system made or any mechanism to reverse erroneous corrections.
The new system mirrors TradingView‘s existing dividend handling workflow. When a data-provider-confirmed split affects a holding, users receive a suggestion detailing the symbol, split date, and ratio. From there, they can accept the pre-filled transaction for automatic portfolio recalculation, leave it pending in Tips for later action, or skip it entirely. All split transactions now reside in a dedicated Splits tab under the Transactions section, allowing users to review, edit, or delete entries at any time.
For existing portfolios, the transition requires manual action. The old automatic adjustment system has been removed entirely with no legacy settings available. Users with positions potentially affected by historical splits should review Portfolio Tips for applicable suggestions and accept them to update portfolio metrics including P&L, average price, and position value. TradingView noted that, unlike the previous background system, portfolio recalculations only occur after users explicitly accept split suggestions or enter them manually.
