Introducing keyboard-based scalping in OpenAlgo inspired from 1cliq

OpenAlgo now includes a new scalping terminal for options, futures, and equity trading, built with Flask and React 19.

It supports both button-based trading and keyboard-based trading. When the 1Click toggle is enabled, traders can place and close orders quickly using keyboard shortcuts, making it useful for fast scalping workflows.

Access it from:

/scalping

or from the page listed below the profile button on the top-right corner.

Current status: Beta / Testing Mode

Update to the latest OpenAlgo version:

git pull

Key features:

• Supports 32+ brokers
• Supports NSE, BSE, NFO, BFO, MCX, and CDS exchanges
• Fixed stop-loss, target, and trailing stop support
• Button-based order placement and exit
• Keyboard-based order placement
• We are actively testing this in live market conditions and will continue fixing issues based on real-world usage.
Please update OpenAlgo, try the new scalping terminal, and share your feedback.
