Most of the common indicators are coded in which language?

<p id="isPasted">I would definitely take a look at Python if I were you. I don't know what your background is with programming at all but it has a few big selling points:</p><p><strong>It's easy to learn</strong></p><p>Python has one of the easiest syntaxes to pick up in my opinion. If you already know how to write proper code you’ll be picking up Python in no time.</p><p><strong>There’s a surplus of libraries</strong></p><p>For pretty much any problem there are libraries that others have written which you can make use of to make solving your problem/writing your program a lot easier. Why rewrite code that's already accessible to you?</p><p><strong>It’s enjoyable to write code</strong></p><p>Not saying that writing in any other language is not enjoyable, but Python has it's own way of writing code that's just so concise/aesthetically pleasing/functional that you'll be able to quickly move your production along in a Pythonic manner.</p><p>Bonus: Python is one of the best languages to learn if you have an interest in machine learning/data science due to all of the modules available to it. I don't know if these apply to you, but I know that ML and investment trading are a hot topic.</p>

<p id="isPasted">For financial trading, common indicators are typically coded in either Python or a platform-specific scripting language like MQL4/MQL5 or Pine Script. The best choice depends on the specific use case, trading frequency, and desired platform.&nbsp;</p><p><strong>Common languages for technical indicators</strong></p><p><strong>Python</strong></p><p>Best for: Backtesting, quantitative research, machine learning, and retail algorithmic trading.</p><p>Strengths: It is easy to learn and has a vast ecosystem of powerful libraries, such as Pandas for data analysis, NumPy for numerical operations, and TA-Lib for technical analysis functions.</p><p>Use case: A trader might use Python to research and refine a strategy offline before coding it for a live trading platform.&nbsp;</p><p><strong>Platform-specific languages</strong></p><p>MetaQuotes Language (MQL4/MQL5): A C++-like language used to create indicators and Expert Advisors (trading robots) on the popular MetaTrader 4 and 5 platforms.</p><p>Pine Script: A lightweight and easy-to-learn language designed specifically for the TradingView platform. It allows users to write custom indicators and strategies that run directly on TradingView charts.</p><p>C# (NinjaScript): Used for coding on the NinjaTrader platform.&nbsp;</p><p><strong>C++</strong></p><p>Best for: High-frequency trading (HFT) and institutional-level systems where every millisecond counts.</p><p>Strengths: Offers superior performance and speed, and is the standard for high-performance computing tasks.</p><p>Drawbacks: More complex to program and maintain.&nbsp;</p><p><strong>R</strong></p><p>Best for: Statistical analysis and academic research, not for live trading execution.</p><p>Strengths: Developed for statistics, R has powerful data analysis and visualization capabilities.&nbsp;</p>
