Plain english → auditable backtest
Your edge, articulated.
Describe a trading idea the way you would say it out loud. StormLedge asks the right questions, writes the code — Python and its own DSL — runs the backtest, and tells you honestly whether the edge is real.
Say it like a trader would
It reads strategies like these.
One conversation, start to finish
How it gets from idea to ledger.
Describe
Give it the ticker, the entry signal, the exit, the stop. Plain English — no syntax to learn.
Watch it think
A visible plan, then code written live in the StormLedge Computer — Python and DSL, side by side.
Backtest
Bars replay in real time against your rules. Trades mark themselves on the chart as they fire.
Read the ledger
Sharpe, drawdown, walk-forward — and an honest statistical verdict on whether there's an edge at all.
storm ledger
What the ledger holds
Every claim, checked twice.
Dual code output
Every strategy compiles to a full Python execution engine and the StormLedge DSL — read, edit, download, or re-run either one.
Benchmarked results
Total return, CAGR, Sharpe, max drawdown, win rate, profit factor — every number measured against the S&P 500, not left to stand alone.
Edge analysis
A composite score across P&L quality, consistency, robustness, and discipline, plus a statistical-significance verdict — so "it worked" has to earn the word.
Walk-forward testing
Run out-of-sample windows on demand and see whether the edge survives data it never trained on.
Nothing hidden in the number
Every backtest ships its own audit trail — fill model, costs, data source, engine version, code hash.
Paper deploy
Watch a strategy trade against live prices with simulated fills and a full log. Zero capital at risk.
