Supported Pine Features

TestMax runs Pine Script v5 and v6 and covers the constructs most indicators and strategies actually use. This page is the definitive matrix: what is supported, what is partial, what is not there yet, and how the runtime behaves when a script steps outside the supported surface.

Language and declarations

Feature	Status
indicator(), strategy() declarations	Supported
input.int, input.float, input.bool, input.string, input.color, input.source, input.timeframe, input.session, input.time	Supported
plot(), hline()	Supported
plotshape(), plotchar()	Supported — rendered as chart markers
var and varip variables	Supported
if / else, for, while, switch	Supported
Series history operator x[n]	Supported
Arrays, matrices, maps	Partial — whatever the transpiler passes through; treat as experimental

ta.* functions

Supported:

Category	Functions
Moving averages	sma, ema, rma, wma, vwma, swma, smma
Oscillators	rsi, macd, stoch, cci, mfi
Bands & dispersion	bb, stdev, variance, dev, atr, tr
Extremes & stats	highest, lowest, highestbars, lowestbars, median, percentrank, linreg, correlation
Change & accumulation	change, mom, roc, sum, cum
Crosses & conditions	cross, crossover, crossunder, rising, falling
Pivots & events	pivothigh, pivotlow, barssince, valuewhen
Volume	obv, accdist, vwap (day-anchored)

Any ta.* function not on this list fails with a descriptive runtime error — it never silently returns wrong values. In particular, ta.supertrend, ta.sar, ta.dmi, and ta.adx are not supported yet and throw a clear “not supported yet” error.

Other built-ins

Feature	Status
math.* — abs, ceil, floor, sqrt, pow, exp, log, log10, trig functions, round, max, min, avg, sign	Supported
na, nz, fixnan	Supported
barstate.* — isfirst, islast, ishistory, isrealtime, isnew, isconfirmed, islastconfirmedhistory	Supported — live values while the open candle streams (isconfirmed is false on intrabar updates)
Time functions — year, month, dayofmonth, dayofweek, hour, minute, second	Supported — evaluated in the exchange timezone
StdPlus extras — Bollinger, Keltner, HMA, and more	Supported

Drawing objects

Feature	Status
box.new + box.set_* / box.delete	Rendered on the chart (background, border color/width/style, text)
line.new + line.set_* / line.delete	Rendered — solid/dashed/dotted styles, width, extend.left/right/both
label.new + label.set_* / label.delete	Rendered — bubble with pointer per label.style_*, text color and size, yloc.abovebar/belowbar anchoring
table.new / table.cell / table.clear	Rendered as a screen-anchored panel (all nine position.* corners)
linefill.new	Not rendered

Drawings honor the indicator’s visibility toggle and are capped at 500 objects per type (oldest evicted), matching TradingView’s max_*_count ceiling.

Not supported yet

Feature	Behavior
request.security() / multi-timeframe data	Not supported
barcolor(), bgcolor(), fill()	Not rendered
alertcondition(), alert()	No-ops — accepted but do nothing
Percent-of-equity position sizing	Not supported — fixed quantity only
ta.supertrend, ta.sar, ta.dmi, ta.adx	Clear “not supported yet” runtime error
Libraries (import)	Not supported

Error behavior

• Compile errors are listed in the error console when you apply a script — click an error to jump to its line.
• Runtime errors are reported with the bar index where they occurred. The first runtime error halts that script instance; other applied scripts keep running. Re-apply the script to restart it.
• Unsupported functions fail loudly. Calling an unsupported ta.* function raises a descriptive runtime error rather than silently computing something wrong.
• History runs time out at 30 seconds. A script that takes longer than 30 seconds to process the chart history halts with a timeout error.

Caution

Calling ta.* functions inside branches that only sometimes execute (for example, inside an if body) can corrupt their streaming state — the same pitfall TradingView warns about with “this function should be called on each calculation”. Call the function unconditionally on every bar, assign the result to a variable, and use the variable inside your condition.

Limits

Limit	Value
Script source size (editor)	100 KB
Imported .pine file size	30 MB (over 100 KB: stored and exportable only — cannot open in the editor or run on charts)
Total script storage per account	100 MB (default)
Saved scripts per account	50
Applied indicators per symbol	10
History run time	30 seconds

Note

Strategy backtest results are simulated OHLC approximations with no intrabar tick path — they will differ from TradingView and from live trading. See the fill model for the exact assumptions.
