SOL Intraday Large-Impulse-Bar Continuation (Single-Instrument USD-M, Long-Short, 1H, Ride Directional Impulse Bars, Tight Initial Stop, Trailing-Stop Winners, Discrete Capital-Capped, Pure OHLCV)

A LONG-SHORT, SINGLE-INSTRUMENT, pure-OHLCV intraday MOMENTUM-CONTINUATION strategy on SOLUSDT.BINANCE USD-M perpetual futures (1-HOUR bars) -- the next asset in the factory's VALIDATED, analyst-endorsed IMPULSE-CONTINUATION family. The ETH instance (EthImpulseBarContinuationTrendLS1H) just PASSED optimization at Sharpe 1.40 (risk_review), and the BTC instance is in pipeline; the analyst's explicit redirect after four basket-refinement failures was 'redirect ALL novelty to the generalizing intraday impulse-continuation family,' and that family is now empirically validated and being populated per-asset (exactly as single-asset TSM was a sanctioned series -- except impulse-continuation GENERALIZES forward where continuous trend/TSM/VWAP forms decayed). MECHANISM (mirrors the proven ETH template): an IMPULSE bar is a 1H bar whose directional body (close - open) exceeds impulse_mult x ATR(atr_period) AND closes in the strong third of its high-low range -- a high-conviction directional thrust (genuine flow/information, not noise). The strategy enters in the impulse direction to capture the short-horizon CONTINUATION before the move is absorbed, with a TIGHT initial stop (cut losers fast) and a TRAILING stop that lets continuation winners run. WHY SOL: among uncovered majors it is the strongest impulse-continuation candidate -- top-4 liquidity (clean signal) and the HIGHEST intraday volatility of the majors, so it produces the most frequent large directional impulse bars (densest walk-forward population, no event-sparsity) and the strongest intraday continuation character (SOL thrusts and follows through harder than BTC/ETH). WHY IT GENERALIZES WHERE OTHER SINGLE-ASSET INTRADAY DECAYED: impulse-continuation is EVENT-DRIVEN and SELECTIVE (only large-conviction bars), the higher-quality signal that made the ETH sibling pass its recent-regime holdout, unlike VWAP-continuation (rode noisy excursions, decayed) and single-asset trend/TSM (continuous, whipsawed, mania-beta). WHAT IT AVOIDS (every closed path): NOT a basket refinement (the prohibited axis -- 4 consecutive degradations); NOT funding/carry (uncreditable in the engine + HL-data-walled); NOT reversion (dead); NOT continuous-rebalance/netting-flip (the 316%/385% sizing-artifact cause -- this uses DISCRETE enter-then-exit-to-FLAT, like the cleanly-sized ETH sibling); NOT single-asset TSM (dead -- different mechanism). EVERY design choice respects the lessons: (1) DISCRETE entries, flat between signals, sized against STABLE realized equity (excl. unrealized PnL), hard-capped <=100% (leverage 1x). (2) FEE-AWARE: fires only on large-impulse bars; SOL's big continuation moves clear the ~0.10% RT floor easily -- NOT scalping. (3) DENSE: hundreds of 1H impulse events/yr -> populates the 3-window walk-forward. (4) PURE OHLCV: no ticks (2-day wall), options (unwired), funding (data ends 2024). Per the 'favor simpler' mandate, 3 tunables (impulse_mult, trail_mult, init_stop_mult) mirroring the proven ETH config.
