A LONG-SHORT, single-instrument, pure-OHLCV directional strategy on DOTUSDT.BINANCE USD-M perpetual that is deliberately NOT the promoted momentum-confluence recipe (BTC/ETH/ADA dual-TF confluence) and NOT a symbol-swap of the volume-confirmed variant that L91 says keeps dying. The core difference is the ENTRY MECHANISM: instead of buying strength (chasing a momentum/breakout at the worst possible price and paying spread at the extreme), it defines a slow trend REGIME on the 1D bar and then enters ONLY on a short-term PULLBACK against that trend on the 4H bar — buying the dip inside an established uptrend, selling the bounce inside an established downtrend. Buying the counter-trend shakeout gives a materially better entry price, so the per-trade capture (mean-reversion bounce + trend resumption) is larger than a breakout-chaser's, which is exactly what is needed to clear the ~0.10% round-trip fee that has killed 462 fee_edge hypotheses. Symbol choice (DOT) is an evidence-driven diversification move: DOT is a deeply liquid, 2020-listed USD-M major with multi-year 4H/1D history, absent from the promoted trio (BTC/ETH/ADA) and from the current pipeline/failure set, so this is not a re-skin of a dead clone. Only 3 parameters to resist the overfit death (381x) that punishes richer parameterizations.
