It is 40+ hours straight of building a openscript (compiler + interpreter)What OpenScript can do nowWrite a study, plot it. 105 built-in indicators. A script compiles in milliseconds in a browser tab, no build step, and computes bar by bar. 101 independently written studies compile, load and run.Backtest a strategy. Orders, position, brackets, sizing, a cost model, fills. What comes back is not a number but a document: the program, the bars, the settings, every frame, every fill, the ledger and the report.Run it on a second engine. A Python engine now reads the same compiled program. Both engines are held to identical numbers at zero tolerance, and the build fails on a single differing bit.Build an editor. Six headless functions: highlight, complete, diagnose, hover, signature, format. Text in, data out, no DOM.

OpenAlgo Script, aka OpenScript, is progressing fast.In the next day or two, you should start seeing more advanced features, better control, and much more flexibility in how strategies and indicators are programmed.The important part is that the entire OpenScript library is open source, so the language itself can keep evolving with the community over time.

A question we often hear is:“Why are you building an algo trading platform? Why not just give us profitable trading ideas directly so we can make money?”The answer is simple.OpenAlgo is built to help traders automate their own ideas using modern technology. We provide the infrastructure, tools, and flexibility to turn a trading idea into something that can be tested, refined, and automated.But we strongly believe that a real trading edge cannot be spoon-fed.An edge has to be discovered.It comes from observation, curiosity, experimentation, testing, failure, refinement, and a deeper understanding of how markets behave.Traders need to think like explorers. Study the market, form hypotheses, test them, learn from the results, and gradually discover what works for them.Someone can give you a strategy, but they cannot give you the understanding behind it.
