Build, backtest, and deploy bots that trade long and short — on a platform obsessed with the hardest half. When the chart drops, your equity doesn't.
Three stages, one loop. The same discipline a peregrine uses to hunt — patience at altitude, then a committed, vertical strike.
Compose entry, exit and risk rules in the visual builder — define what a breakdown looks like and how to trade it. The rule engine runs your rules exactly as written, no code required.
Run your rules against real market history, split into in-sample and out-of-sample so the results can't flatter you. See win rate, profit factor and expectancy before a cent is at risk.
Paper-trade first, then flip to live. The bot watches the tape through every market session, sizes positions to your risk budget, and stoops the instant your setup triggers.
See borrow availability and fees per ticker before you commit to a short — the numbers shorts actually live and die by — with hard-to-borrow locates supported through your broker.
Per-trade stops, daily loss limits and a one-tap emergency stop that flattens everything — from your phone if you have to.
Out-of-sample validation on real market history. Win rate, profit factor and expectancy — and if the edge isn't there, the report says so.
Compose strategies visually; a deterministic rule engine runs them — the exact same engine in backtest, paper and live. What you tested is what trades.
Live P&L, exposure and per-bot health. Push alerts to your phone when a risk rail trips or a bot goes offline.
Trades through Alpaca today — the engine is broker-agnostic, with more brokers on the way. Your capital stays at your broker — Peregrine never touches custody.
Shorting punishes sloppy risk faster than any long book. Peregrine backtests your rules on real market history — including data your strategy has never seen — and lets you prove them on paper before a single dollar goes short.
Hypothetical example — not a real or achieved result.
Six built-in presets cover the recurring short setups — premarket gaps, VWAP breakdowns, momentum bursts, range fades. Every threshold, filter and exit is yours to retune. Or skip the templates entirely and compose your own rules from scratch.
Scans for premarket gap-ups, then shorts the break below VWAP at the open. Gap range, VWAP trigger and exits all adjustable.
Trades the gap itself — long on gap-ups, short on gap-downs, or lock it to short-only. Gap size and confirmation filters are yours to set.
Shorts near resistance, covers near support — using levels you set on the chart. Entry threshold and stops are configurable per ticker.
Plus VWAP Crossover, MA Crossover and Fast Mover — six presets in total, all direction-configurable and none of them fixed.
Build your first short-selling bot in minutes. Paper-trade free — go live when the numbers earn it.
