Indicator values differ because ChartIQ and TradingView are two separate, independently developed charting libraries. Each library has its own implementation of the same indicators.
Calculation methods, default parameters, and data handling can differ slightly between the two engines. Therefore, an indicator can show a different value for the same stock on each platform, even though both values are technically correct for their respective engines.
If you require identical numerical indicator values across both platforms, you must check and align the indicator settings manually where possible.
