Every TradingView indicator and strategy in our marketplace has been recompiled against Pine Script v6. The migration touches type handling, series initialisation and a few renamed built-ins, so scripts that were copied and edited locally may need small fixes.
The most common breaking changes we hit: stricter typing on user-defined function arguments, explicit na handling in conditional expressions, and updated behaviour of request.security when the higher timeframe has gaps.
Nothing changes visually in the published versions — signals, alerts and plot styles are identical to the v5 releases. If you compare v5 and v6 side by side on the same chart, the outputs match bar for bar.
Legacy v5 versions stay published for one more quarter so that automated setups and alert templates have time to move. After that only v6 builds receive updates and support.
