"""
Github_crow2673_Echo_core__EchoL1StrategyV6__20260503_192400 — Long AND short. Profits in any market direction.

V4/V5 problem: long-only strategy loses in bear/sideways markets.
An AI should profit regardless of direction.

V6 adds short selling:
  Long:  RSI recovery from oversold + MACD turning up   + near MA50 + volume
  Short: RSI reversal from overbought + MACD turning down + near MA50 + volume

Exit: 5% TP | 2% SL (tighter — crypto moves fast both ways)
No trailing stop — let signals run to target.

Expected: long signals fire in dips, short signals fire at tops.
Net result: profits in bull, bear, AND sideways markets.
