PyneCore v6.11.0 released — a per-line profiler for backtests with pyne run --profile,…

October 25, 2026

Features

pyne run ... --profile prints where a backtest spends its time: slowest lines with time, share, execution count and average, plus a category split (script, libraries, engine, output, data, security). --profile-top N sets the line count
request.security contexts are profiled too, each with its data, timeframe, bars and script time
ScriptRunner(profile_path=...) writes the same JSON profile programmatically (Python 3.13+)
Methods declared in @udt class bodies can now hold state (ta.*, Series, Persistent), per call site; edge profile 2026.10.2 admits them

Fixes

Aggregating to weekly and monthly timeframes works; monthly targets were always rejected before
time("D", timeframe_bars_back=N) no longer raises IndexError without a session template
Importing pynecore.core.script before pynecore.lib no longer fails
Generated code runs at the source line it serves, so debugger stepping, tracebacks and line timings point to the right line
Scripts starting with a from __future__ import compile with request.security and as strategies
