Parameter sweep optimizer

Sweep Pine strategy parameters before you publish

Use the desktop beta to test fast, slow, RSI and MACD variants, then inspect top PnL candidates and benchmark throughput.

For strategy authors who need a faster first pass before manual review, out-of-sample tests and TradingView validation.

TradingView Pine Strategy Optimizer: sweep first, publish later.

The paid path is not the first sweep. It is the saved history, private report URLs and bigger Operator diagnostics after a candidate survives the local optimizer.

What it does

Strategy Arena Lab generates native ArenaScript candidates, runs Operator composite sweeps across 70 native families, can import supported Pine Script into the same plan format, then runs deterministic local backtests before any public validation workflow.

Why it matters

Trading strategies need repeatable local checks, visible trade logs and benchmarkable parameter sweeps before they become marketing claims.

Beta scope

  • SMA, EMA, RSI, MACD and EMA + RSI subsets
  • Long and short CPU reference paths
  • CUDA comparison where supported
  • Native GPU name, source and adapters in benchmark metadata

Pine compatibility without losing the ArenaScript engine

The Lab is not a TradingView extension. It generates and backtests Strategy Arena ArenaScript strategies first. Pine is an import bridge for deterministic subsets; CPU reference is the truth source, then CUDA runs only when a script maps to current kernels.

Supported ArenaScript generation, Operator composite, strategy.entry, SMA/EMA/WMA/HMA/ALMA/VWMA/RMA crossover/crossunder/cross and price-vs-MA crosses, Stochastic, CCI, ROC, CMO, ta.change, ta.mom, Williams %R, ADX, MFI, OBV, Bollinger, Keltner, SuperTrend, Parabolic SAR, Linear Regression, VWAP, WMA Cross, HMA Cross, ALMA Cross, VWMA Cross, ATR, Donchian, numeric inputs Native Strategy Arena candidates, Operator composite generated families and compatible Pine signals map into CPU reference runs, sweeps and current CUDA paths, including direct ta.crossover/ta.crossunder/ta.cross, inline ta.sma(close, fast), ta.ema(close, fast), ta.rma(close, fast), ta.stoch, close-based ta.cci, ta.roc, ta.cmo, ta.change close momentum gates, ta.mom close momentum gates, ta.wpr, pure ta.dmi ADX threshold plus ta.crossunder/ta.crossover/ta.cross gates, DMI plusDI/minusDI direction gates, close-based ta.mfi money-flow gates, oscillator ta.crossunder/ta.crossover/ta.cross threshold gates, ta.obv(close, volume) volume momentum gates and assigned or inline threshold plus ta.crossunder/ta.crossover/ta.cross gates, ta.vwap(close) assigned or inline price gates plus close crossover/crossunder VWAP gates, ta.bb tuple bands and inline ta.sma(close, length) +/- ta.stdev(close, length) * mult formulas plus close crossover/crossunder band gates, ta.kc tuple channels and inline ta.ema(close, length) +/- ta.atr(length) * mult formulas plus close crossover/crossunder channel gates, ta.supertrend line gates, close crossover/crossunder line gates and direction < 0 / > 0 gates, ta.sar, ta.atr and Donchian gates including short-form ta.highest(length)[1] / ta.lowest(length)[1].

Rejected request.security/request.financial, non-close sources, strategy.order/risk, broker state, barstate/timeframe, arrays/maps, loops, alerts, drawings Repair path: flatten to one local bar stream, replace broker/runtime state with explicit ArenaScript entry, exit, stop, take-profit or timeout rules, then rerun CPU/CUDA research.

Does it prevent overfitting?

No optimizer can guarantee that. The app makes sweeps visible and exportable so you can review candidates more rigorously.

Which parameters are supported now?

The beta targets fast, slow, rsiLength, rsiThreshold and MACD fixed-signal variants in the supported Pine subset.
