SignalMomentumChainlinkBaseCrypto

A simple, fully disclosed momentum signal from Chainlink on Base: current price versus the price 24 oracle rounds earlier, percent change, and a label (up / down / flat, threshold 0.5%). Pass ?pair=ETH-USD (default). The method is the whole product: no model, no secret sauce. Not financial advice.
