GET /api/history

live

Rolling 90-day backtest of WaveTrend 10/21/4 band dots on 66 Kraken 4h USD pairs, recomputed live. Green dots carry the edge (recent window: outer green dots ~64% higher after 3d); red dots are near coin-flip and reported honestly. Per dot: pair, green/red, inner/outer, wt1/wt2, price, forward % +4h/+24h/+3d, plus live hit-rate summary. Optional ?pair=BTC. $0.05.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
