"""TR01 — EMA Trend Following (long-only), timeframe 4h.

Cavalca i trend rialzisti, si mette in cash nei downtrend. Niente short
(shortare cripto perde OOS nel campione 2018-2026). Complementare a DIP01:
DIP01 guadagna nei regimi di reversione, TR01 nei regimi di trend.

Logica:
    1. EMA fast (20) e EMA slow (100) sul close
    2. LONG quando EMA_fast > EMA_slow (uptrend), altrimenti CASH
    3. posizione continua, decisione a close[i] (no look-ahead);
       fee solo sui cambi di stato (poche operazioni = fee non letali)

Validazione (netto, fee 0.10% RT, leva 3x, pos 15%, OOS = ultimo 30%):
    robusto FULL+OOS su 5/8 asset: BNB(+14), BTC(+27), DOGE(+53), SOL(+7), XRP(+29) OOS.
    ETH ~flat, ADA/LTC negativi OOS -> preferire BNB/BTC/DOGE/SOL/XRP.
