SmaRegime720

"""
SmaRegime720 — long only inside confirmed uptrend on 1h data.

Hypothesis: TrendFilter200 failed because 200 periods on 1h (~8 days) is too
short to define a crypto regime — every bear-market bounce triggers a bull-trap
entry. Two fixes applied here:
  1. Window = 720 periods (≈30d) — stable enough to survive short bounces.
  2. Slope gate — SMA must itself be rising (sma720 > sma720 24 bars ago)
     before an entry is accepted. This blocks entries when price pops above a
     still-declining SMA.

Entry:  close crosses above sma720  AND  sma720 is rising (slope > 0).
Exit:   close crosses below sma720 (regime ends — exit immediately).
