✨ Features
🎯 100% Pine Script v6 Coverage
- 6,665 language constructs from official TradingView reference
- 457+ functions with autocomplete (ta., math., str., array., etc.)
- 31 constant namespaces (xloc, yloc, extend, scale, display, etc.)
- 22 function namespaces with full parameter validation
- 32 strategy. variables* (position_size, equity, netprofit, etc.)
🧠 Semantic checks — catches code that compiles and is still wrong
- Repainting —
request.security() reading the current, forming bar
ta.* in a conditional — silently corrupts the indicator's own history- Accumulator lifetime — a
var total a loop re-adds to every bar and never resets, so it grows for the life of the chart
- Scope errors —
plot/bgcolor inside if, functions defined in a block
- Platform limits — 64 plots, 40
request.*() calls, counted before TradingView rejects you
- Unbounded risk —
strategy.entry with no exit anywhere
Suppress one you have considered: // pine-ignore: S1
🔍 Real-Time Validation
- Catches undefined functions and variables
- Detects missing/extra parameters
- Validates namespace properties
- Zero false positives on the golden corpus — four committed fixtures
exercising every construct that has ever produced one, asserted clean on every
commit, plus real scripts checked locally
💡 Intelligent IntelliSense
- Smart autocomplete for all built-in functions
- Parameter hints with type information
- Hover documentation
- Namespace-aware suggestions
📝 Syntax Highlighting
- Complete Pine Script v6 syntax support
- Built-in variables and constants
- Keywords, operators, and functions
- Comments and strings
📖 Usage Examples
Valid Pine Script v6 Code
//@version=6
indicator("My Indicator", overlay=true)
// All valid v6 syntax - no false positives! ✅
length = input.int(14, "Length")
source = input.source(close, "Source")
// Technical analysis with autocomplete
sma_value = ta.sma(source, length)
ema_value = ta.ema(source, length)
rsi_value = ta.rsi(source, 14)
// Math functions with precision parameter
rounded = math.round(close, 2) // ✅ v0.4.4+ supports precision
max_val = math.max(open, close)
// Strategy variables fully supported
if strategy.position_size > 0
plot(strategy.equity, "Equity")
plot(strategy.netprofit, "Net Profit")
// Plot with all v6 constants
plot(sma_value, "SMA", color=color.new(color.blue, 50), style=plot.style_line)
plot(ema_value, "EMA", color=color.new(color.red, 50), style=plot.style_linebr)
// All namespace constants work
x = xloc.bar_index
y = yloc.price
e = extend.both
s = scale.left
🔧 Configuration
The extension works out of the box with zero configuration. All Pine Script v6 features are automatically recognized.
📊 What's New in v0.6.1
Semantic checks — catches code that compiles and is still wrong
Repainting request.security, ta.* inside conditionals, scope errors, platform
limits, entries with no exit. Suppress one you have considered with
// pine-ignore: S1.
The engine is now a package
Published as pinescript-v6-validator
and shared with the agent plugin, so both cannot disagree about a file.
False positives eliminated (0.5.x)
The coordinate forms of line.new, label.new and box.new are official v6
overloads, but the bundled reference only carried the chart.point form — so
correct code lit up red. Overloads are now modelled properly.
// Before v0.5.0: 10 errors on these three lines. Now: clean. ✅
line.new(x1=bar_index[1], y1=low[1], x2=bar_index, y2=high)
label.new(x=bar_index, y=high, text="hi")
box.new(left=bar_index[5], top=high, right=bar_index, bottom=low)
Also fixed: for … in loop iterators, comments and blank lines inside wrapped
calls, nested parentheses in arguments, user-defined type/enum namespaces, and
two indentation rules TradingView removed in December 2025.
12.8× faster
A 1,302-line script validates in 12.3ms, down from 158ms.
Caught up with Pine v6
Ten months of TradingView releases the bundled reference was missing —
multiline strings ("""…"""), request.footprint(), calc_on_every_history_tick,
sort_field, active on inputs, timeframe_bars_back, syminfo.isin,
box.set_xloc().
A real test gate
67 → 169 tests, including a golden corpus asserted to produce zero errors and
paired "must still flag" cases for every fix — so a check can never be quietly
deleted instead of repaired.
See CHANGELOG for complete version history.
🧪 Testing
- 169/169 tests passing (100%)
- Golden corpus: four committed fixtures asserted to produce zero errors, and
proven able to fail — reintroducing a fixed bug turns them red
- Paired regression tests: every false-positive fix ships with a "must still
flag" counterpart, so a check cannot be silently deleted instead of repaired
- Performance budget: enforced in CI (<100ms for a 1,300-line script)
npm test # full suite
node validate-cli.js file.pine # headless single-file validation
