Our world is becoming increasingly automated. Completely self-driving cars are only years away and smart home robots are already here. The same can be said of trading – an extremely competitive industry. One way to stay ahead of the competition is by acquiring and leveraging specialized skills.
PineScript is an exclusive programming language created by TradingView to backtest trading strategies and write custom indicators that could be used in technical analysis. Pine Script is one of the best charting tools and is used very widely globally. Among other things, it allows traders to save time in backtesting and analysis, avoid missed opportunities, enhance their edge over the markets, and remain competitive on the cutting edge of trading.
One key thing about Pine Script is that it is quite easy to learn with a syntax that resembles written English. It is also extremely quick to code in and compiles very fast to plot charts that allow you to analyze price data much faster, easier, and more efficiently.
You can write Pine scripts that do any of the following:
- Draw charts – plot your analysis information onto your chart for fast and easy order execution.
- Backtest strategy ideas – automatic backtesting over dozens of markets and leveraging countless trades and decades’ worth of price data across multiple timeframes. This is instrumental to help you identify and optimize potential profitability.
- Trigger alerts – stay on top of the markets at all times by creating custom alerts that bring your attention to important developments.
- Manage trading positions – automatically manage trading positions through 3rd party services and APIs.
- Modify existing indicators – adjust your existing indicators to suit your trading style or technical analysis preferences.
- Backtesting aids and tools – create Pine Scripts that simplify and speed up the manual backtesting process.
With over 10 million users on TradingVIew, Pine Script has grown to become a popular tool among traders. This demand has naturally resulted in more beginners and advanced programmers who need more resources to master this invaluable trading tool. I often receive emails from traders who want to learn new features or simply make better sense out of the scripts they are already working with. So I decided to put together a list of the most common questions (FAQs) about Pine Script.
