Typed connections
Typed ports keep data and control flow explicit, so invalid wiring is caught before the strategy reaches a backtest.

canvas/editorACTIVELogic you can see. Rules you can defend.
Screebits gives you a visual editor for trading logic. Build entry, filter, exit and allocation rules as nodes on a canvas, with typed connections and visible data flow. If you can wire it, you can explain it. If you can explain it, you can test it.

A strategy you can inspect
Your idea becomes a structure you can review, share and refine across tactical setups and portfolio allocation flows.
Tactical and portfolio logic
Move between single-strategy rules and portfolio allocation flows without leaving the canvas. Each mode keeps the right building blocks for the decision you are designing.
rail/validationACTIVEBroken logic never reaches the market.
Screebits flags missing inputs, invalid order settings and blocked handoffs while the strategy is still easy to understand.
Try it: this order needs a Quantity input. Connect Quantity and the backtest action unlocks.

run/backtestACTIVEHistory gets a vote before your money does.
Replay a strategy across historical market data and read return, risk, drawdown and trade behavior side by side. The evidence stays attached to the exact rule set that produced it.
Rule set under test
Entry - RSI(14) Condition crosses below 30 on bar close, then triggers a Buy Order.
Filter - Logic Gate requires higher-timeframe trend confirmation before the Order runs.
Exit - Position Monitor manages take profit, stop loss, and RSI recovery above 60.

We're finalizing plans for launch - and a free plan is part of the lineup. Join the newsletter to know when checkout opens. Curated Blueprints have no separate price; modes and nodes still depend on your plan.
