Features

Built for the moment you click

Everything here works today, on mock, replay and live crypto feeds.

Chart trading

See and drag your orders on the chart. Drag from the position line to set a stop or target. Exits are reduce-only and can never flip you.

DOM that holds still

A fixed-row ladder with market buttons, brackets, and a price trail. The layout never shifts under your pointer.

Order flow

Footprint, volume profile, cumulative delta and VWAP, rebuilt from stored trades the moment you open the app.

Any bar you want

Time, tick, volume, range and seconds bars. Type 500t, 10r or 5 and press Enter.

Prop rules and guardrails

Daily loss, trailing drawdown, max trades and cooldowns, enforced before the order leaves, never after.

Journal and strategies

Every round trip with MAE/MFE and tags. Strategies run on paper through the same rules as your clicks.
