An RSI script is useful when you need a specific display or alert rule. TradingView's built-in RSI already supports configurable inputs; custom code lets you make the conditions explicit and combine them with other logic. The example below plots RSI and distinguishes entering an extreme zone from leaving it.
Converting Pine Script to MQL4 means preserving trading rules across two execution environments. A converter or AI tool can draft target code, but successful compilation does not establish that an MT4 Expert Advisor behaves like the original TradingView strategy. The useful question is which behaviors the conversion preserves and how you will verify them.
This Pine Script tutorial builds a moving-average indicator, then shows what changes when you want simulated trades. The examples teach inputs, plots, conditions, and order timing. Their parameters are learning choices, not tested trading recommendations.
Pine Script v4 is a legacy language version that still appears in published indicators and older projects. TradingView announced it on June 25, 2019. Reading v4 accurately means distinguishing its APIs from later versions: study() and input() belong in v4 code, while the indicator() declaration and specialized input functions are part of the v5 migration.
The official Pine Script v5 manual is available free on TradingView's website. Pineify also maintains a Gumroad listing for a PDF conversion of that manual. The PDF listing is published by Pineify; it should not be described as an official TradingView PDF distribution.
Pine Script v6 arrived in 2024, not late 2025. It changes several language defaults and removes some older behavior. A useful migration review checks the resulting calculation and order timing as well as the compiler output; the version annotation alone does not establish equivalence.
A Pine Script strategy expresses trade rules and produces simulated orders in TradingView. This guide includes one moving-average code example and two additional rule specifications to test. It explains what the example actually does, which assumptions are missing, and how to record a reproducible run. No verified profit, win-rate, or drawdown result accompanies these examples.
Pineify offers a free PDF conversion of the Pine Script v6 user manual through Gumroad. The official, continuously maintained documentation is on TradingView's website. Use an offline copy for reading and the live reference to check the behavior of the functions you use.
Pine Script v5 remains relevant when maintaining an older project or converting v4 code on the way to v6. Its specialized inputs, expanded namespaces, libraries, and control structures changed how scripts are organized. They do not establish that every converted script runs faster or produces better trading results.
Pine Script's request.footprint() provides bar-level footprint objects and price-row data. TradingView classifies the underlying lower-timeframe volume as buying or selling from intrabar price movement. Treat these values according to that method; they are not proof that every transaction was independently identified as an execution at the bid or ask.
