leverage: a chrome extension for trading gold off tradingview
We started building a chart validation tool for the way one of us actually trades. Vision model on top, deterministic price checks underneath.
At the end of April we started building Leverage, a Chrome extension that captures the trader's live TradingView chart, sends it to a vision model on our VPS, and returns a structured read: take, wait, or invalidated, with direction, entry, stop, and targets.
The motivation was selfish. One of us scalps gold on the 1 minute. The workflow before this was open chart, mentally validate, take or pass, repeat. The handoff to AI was a quick screenshot into another window, paste, wait, parse the answer, switch back. Slow enough to skip when the setup actually mattered.
So we built the tool inside the chart instead. Open the popup, click scan, the screenshot fires from the active TradingView tab and you get a verdict within ten seconds. The model is told it is reading a gold or silver chart, given session context like London open and NY overlap and the killzones, and given a checklist to fill in so the reasoning is visible rather than hand waved.
The thing that took longest was not the prompt. It was the small stuff. Making sure clicking Scan does not close the popup. Making sure the active tab is TradingView before the capture fires. Capturing without stealing focus from the user's window. Each of those felt like one line of code and ended up being a day of figuring out what Chrome MV3 actually does.
The first real test was a Friday night. Someone took a short on the model's call. The setup played out. The next morning we started building everything else.
