name: scalping
description: Use when writing a high-turnover intraday strategy on Superior Trade — anything described as scalping, momentum bursts, fast in/out, RSI thrust, volume spike entry, 5-minute strategy. Note this template was unprofitable in our reference backtest (33% WR, -0.34%); use it as a structural template, not a recommendation.

Strategy: Scalp · Momentum Bursts

When to use

A user asks for a scalping strategy, "fast in/out", "5m strategy", "ride the thrust", "buy when volume spikes". Single-pair, tight stops, time-stopped trades.

Honest framing

The reference backtest below was **unprofitable** (33% WR, −0.34% PnL, Sharpe −5.6) on SOL 5m over April 2026. The strategy *executes correctly* — it's not broken — it's just a losing parameter set on this window. The 0.6% target / 0.4% stop ratio needs ~41% hit rate to break even before fees, which the entry filter didn't deliver. **Do not deploy as-is.** Tune the entry threshold and validate before recommending to a user.

This skill exists as a **structural template** for high-turnover momentum entries. Real edge requires parameter search, regime filtering, or a different signal.

Tunable parameters

| Knob | Effect | |---|---| | `rsi > 70` | Stricter (`> 80`) → fewer entries, only the strongest thrusts. | | `vol_thrust > 2.0` | Tighter (`> 3.0`) → only volume blowouts; very rare. | | `0.006` ROI | Wider target → more time in trade, more tail risk. | | `0.004` stop | Tighter stop → more stops out, lower per-trade loss. | | `12 * 60` time stop | Faster timeout → more trades but lower edge per trade. |

Why this loses (and how to fix)

Three structural issues in the reference parameters:

1. **No regime filter**: enters in chop AND in trend. Chop kills the 0.6% target before it hits. 2. **Entry on overbought + thrust**: RSI > 70 *plus* high volume usually marks a local top, not a continuation. Inverting (`rsi < 30 + vol_thrust > 2.0`) for a fade entry is worth testing. 3. **Single pair**: Scalping edges thin out on a single asset. Top-30 perp scan with `VolumePairList` increases hit count, lets the law of large numbers help.

Practical refinements before suggesting to a user:

• Add a higher-timeframe trend filter (`1h close > 1h ema_50`).
• Use ATR-scaled stops instead of fixed 0.4%.
• Test the inverted (mean-reversion-on-thrust) variant.

Common pitfalls

1. **Slippage eats the edge.** A 0.6% target on a 5m candle leaves ~3 ticks of room. With Hyperliquid taker fee + slippage, effective edge is closer to 0.4% — barely above the stop. See `fees-optimizations`. 2. **`startup_candle_count` too low.** The 288-bar VWAP needs 288 bars of warmup; default 30 produces NaN VWAP for the first 24h. 3. **Single-pair scalping is undercapitalized signal.** 76 trades / 30 days is fine for statistics, not for an edge.
