Omid Spinner & Canceler by omid

Omid Spinner & Canceler is a lightweight productivity add-on for traders using setinrate.com. It injects a small content script on the trading room pages to add ±1 buttons for fine adjustments and ±10 quick-change controls beside both the price and volume (amount) inputs, plus a reliable 'Cancel All' button integrated into the order form.

All UI changes are local to the page: the extension does not send any data off the user’s browser, does not collect telemetry, and does not require an external account. The code is plain JavaScript (no bundlers or minifiers). Compatible with Firefox and Firefox for Android.
