Updates and stories from the PyneSys team — about Pine Script, Python, trading, and the craft of building tools for traders.
What PyneCore does to your Python before it runs it
Pyne code looks like ordinary Python, but Python forgets everything between calls and Pine remembers. Here is the rewrite that closes that gap, shown on a real script, and how I made it more than twice as fast without changing a single byte of its output.

Pine's int type has no runtime existence: it is an IEEE-754 double that loses digits above 2^53, never overflows, and whose na is a NaN. Measured from Pine itself, with a script you can paste into the editor.

Two CC0 examples that bridge Pine Script and FreqTrade through PyneCore: drop Pine indicators into your Python strategy, or let a Pine strategy generate the buy/sell signals FreqTrade executes.

AI tools produce Python that looks right but computes different values than TradingView. Here's why — stateful execution, na propagation, warming behavior, request.security, look-ahead bias — and what to do about it.
