Usage Guide
Getting Started
Start the OpenAlgo Server: Make sure the OpenAlgo server is running (default:
http://127.0.0.1:5000)
Configure Settings:
Click the 3-dot menu icon next to the button panel
Fill in the following fields:
Host URL (e.g.,
http://127.0.0.1:5000)API Key
Symbol (e.g.,
RELIANCEorNIFTY27APR25FUT)Exchange. The dropdown offers exactly six values: NSE, BSE, BFO, NFO, MCX and CDS
Product (MIS, NRML, CNC)
Quantity (e.g., 10, 20, etc.). Futures or Options symbols it is always the total number of shares instead of Lot Size
Save Settings: Click Save to apply your configuration
Settings are stored in Chrome's synced storage, so they follow your Chrome profile across machines. Every field is mandatory: if any one of them is blank the buttons refuse to fire and the settings panel opens instead.
Trading Actions
LE (Green): Long Entry (Buy to Open)
LX (Yellow): Long Exit (Sell to Close Long)
SE (Red): Short Entry (Sell to Open Short)
SX (Blue): Short Exit (Buy to Close Short)
The two entry buttons post a MARKET order to /api/v1/placeorder with your configured Quantity, and OpenAlgo records the strategy as Chrome.
The two exit buttons post to /api/v1/placesmartorder with position_size set to 0. That tells OpenAlgo to look up your live open position for that symbol, exchange and product and flatten it, whatever its size and direction. Two consequences worth knowing:
An exit closes the whole position. The Quantity field in settings is not used for exits.
If there is no open position, nothing is sent to the broker and OpenAlgo replies that the position already matches.
The extension is a content script registered against all URLs, so the button bar can be injected on any page you have open, not only charting sites. It can be repositioned anywhere on the screen.
Draggable Interface
Hover over the top edge of the trading bar to reveal the grab handle
Click and drag to reposition the widget anywhere on the screen
