Every exchange on earth keeps a perfect record of your fills. Price, size, time, fee. Down to the penny.
What it doesn't keep is the part that actually mattered. Funding was screaming positive. Open interest had just jumped. Somebody's 50x long got liquidated thirty seconds before you clicked buy.
That's the stuff that decides whether a setup is an edge or a coin flip wearing a nice suit. And it's gone the moment the candle closes.
I'm a solo founder. In January I started building Thrive to fix exactly that. It's a crypto trading journal that saves the market around every trade, so six months from now you can ask "do my longs work when funding is positive?" and get the answer from your own history instead of your gut. It's read-only. It can't place an order or touch a dollar. It launches on Product Hunt tomorrow.
