How to reverse engineer any TradingView indicator: I took the most popular one, Smart Money Concepts by LuxAlgo, ported it to Sierra Chart with Claude Code, then exported both sides to check it bar by bar. It got 80 to 90% of the way there. One zone was missing.

Why port a TradingView indicator at all? Data. My TradingView plan loads about 20,000 bars; Sierra Chart has data back to 2011, so I can backtest over years instead of weeks. The method is six steps: find the indicator, save the TradingView export, port the Pine Script with Claude Code, drop it in ACS_Source, build it, and match it. Matching is the step that matters: looking right on the chart isn’t the same as being right.
Open source is the easy case. Free but closed: export the CSV across timeframes and let Claude Code fit it. Invite-only or paid: leave it alone. Read the license before you port anything.
