Everything about Alpha score.

wavealgo is a neutral measurement system for trading strategies. It backtests Pine Script strategies across 6 markets (BTCUSD, ETHUSD, SPX500, QQQ, GOLD, EURUSD) and 3 timeframes (1H, 4H, 1D) — 18 cells in all — producing an alpha score from 0 to 100 and one of four verdicts: Verified, Conditional, Repaints, or No alpha. It is not a signal generator, broker, or indicator seller — it is an independent grader that applies the same rules to every script.

The alpha score runs 0 to 100 and is built from four measured parts: out-of-sample edge (0-40), regime stability across the 18 cells (0-25), a flaw penalty (0 to -25) and reproduction accuracy against an independent engine (0-10). A strategy must work across markets to score well — a single-symbol overfit that shines on Bitcoin and fails everywhere else loses almost all of the stability component. Alongside the number sits one of four verdicts: Verified, Conditional, Repaints, or No alpha.

wavealgo tests every strategy against 6 markets: BTCUSD (via Binance BTCUSDT), ETHUSD (via Binance ETHUSDT), SPX500 (via SPY proxy from Yahoo Finance), QQQ, GOLD (via GLD proxy), and EURUSD. This covers crypto, equities, commodities, and forex — ensuring strategies are evaluated across diverse market conditions.

Three timeframes: 1H, 4H and 1D. Cells are deliberately not equal length — each uses whatever history its source provides, so daily cells run 3,278–4,000 bars, 4H runs 1,707–19,653 and 1H runs 5,090–78,545. That is why the composite Sharpe is the median of the 18 cells rather than the mean.

Each of the 18 cells produces a Sharpe ratio. The composite is the median of the 18 — a median, not a mean, because cell windows differ by an order of magnitude. The alpha score is then built from four measured parts: out-of-sample edge (0 to +40, from the composite Sharpe), regime stability (0 to +25, from how many of the 18 cells are positive), a flaw penalty (0 to -25 for static repaint or look-ahead findings) and reproduction accuracy (0 to +10, from engine parity against an independent implementation). The full formula and the four verdict rules are documented at wavealgo.com/methodology.

Not yet. Scoring requires a strategy() declaration with strategy.entry and strategy.close calls, because there must be entry and exit rules to measure. Indicator-only scripts (those with only indicator() and plot calls) still compile and chart in the playground, but they cannot be graded.

Most of it. The leaderboard, the methodology, the corpus sweep, the playground and the quick check are free and need no account. The MCP server gives anonymous callers 10 measurements per rolling seven days, and signing in to create a key raises that to 50 a day. The one paid product is the private audit of your own script: a one-time $99 pilot, paid in crypto after we confirm the source and scope, with no subscription. If the script is outside the pilot's fixed scope, no payment is taken.

TradingView's Strategy Tester evaluates one symbol and one timeframe at a time. wavealgo tests across 18 cells simultaneously (6 markets × 3 timeframes) with uniform fee assumptions. This cross-market validation reveals overfit strategies that look profitable on a single chart but fail everywhere else — something TradingView's tester cannot show.

Backtrader and QuantConnect are execution frameworks — you write Python code and run backtests. wavealgo accepts Pine Script directly (no manual porting required) and provides a standardized, comparable grade. wavealgo is a measurement tool for evaluation and triage, not an execution platform for live trading.

All strategies are tested with 0.05% commission per side, which is the midpoint between Binance spot fees (0.10%) and a discount stock broker (0.005%). Initial capital is 100,000, sizing is 100% of equity per entry (long-only), and market orders fill at the next bar open — the rule TradingView documents. Slippage is not modeled in v1. Full assumptions are documented on the Methodology page.

The v1 reference catalog is the twenty best-known public techniques, and none of them earned Verified: 16 came back Conditional, 4 had no alpha at all, and the highest score was 49 of 100. In all twenty, the median of the 18 cells finished behind simply holding the asset. A wider sweep of 12,424 public scripts is published separately on the corpus page.

Single-symbol overfit is the most common failure mode. A strategy tuned on one market (typically BTCUSD) and never tested elsewhere will often score well on that market but collapse on the other five. The 18-cell matrix is designed to catch exactly this pattern.

A Model Context Protocol server at https://www.wavealgo.com/api/mcp. Claude, Codex, Cursor, VS Code and other MCP clients can use it to measure a Pine strategy across the same six markets, with fees charged, and get a shareable report link without leaving the editor. The figures are bench figures — in-sample, no guards, not an audit, and no alpha score or verdict. Its tools are measure, diagnose, catalog, audit and explain_harness. Compiler diagnostics and catalog lookups are free; measurements are limited to 10 per rolling seven days without an account. Setup is at wavealgo.com/mcp. The execution engine underneath is open source (github.com/nullarch/resin).

Yes. The Pine Script compiler and runtime that executes every audited script is resin, Apache-2.0, at github.com/nullarch/resin. It is verified bar-by-bar against an independent implementation on 251 of 257 corpus scripts, and it is the same engine running in your browser on the playground. A companion adapter renders its output on TradingView’s open-source lightweight-charts.

Yes. The full methodology — including the 18-cell matrix, the alpha formula, the verdict rules, fee assumptions, and known limitations — is documented at wavealgo.com/methodology. The execution engine is open source at github.com/nullarch/resin. There is no hidden model, no stochastic component, and no per-user tuning.

Not as an alpha score or a verdict — those come only from the offline audit pipeline that runs the whole 18-cell grid under fixed rules, and you can request one at wavealgo.com/audit. You can measure your own Pine strategy across six markets through the MCP server, which returns bench figures and a shareable report link — in-sample, no guards, not an audit. The playground compiles and charts any Pine script in your browser without grading.

wavealgo supports Pine Script v5 and v6. The engine handles strategy declarations, indicator functions, UDFs with var/if/for/while blocks, and per-bar execution. Known limitations include inline cross calls inside if blocks (bind to a variable instead) and some advanced request.security patterns.
