HotCoinLab watches short price and trading-activity windows across six exchanges, keeps weak alerts in the history, and shows what happened next.

I built HotCoinLab after repeatedly opening 24-hour gainers lists and realizing the interesting part had often happened hours earlier. The first version tried to keep the feed clean by showing only strong-looking alerts. That made the product look better, but it also hid the cases I needed in order to improve the detector. The current version keeps the awkward alerts too. If a move fades, it stays in the history. If the market data looks unusual but I can’t verify an outside cause, the event says “unconfirmed” instead of inventing an explanation. It currently watches Binance, Upbit, Bithumb, Coinbase, Bybit and Kraken. It is not a trading-signal or price-prediction service. The main thing I’m trying to learn now is where the useful threshold sits between a quiet feed and an honest but noisy one. I’d really value blunt feedback on the alerts that feel unnecessary.

The "history of weak alerts" approach is actually clever since most alert tools only show what triggered, not what got filtered out. Spotted a false flag from last week and could see exactly how the price moved after, which makes tuning my thresholds way easier.
