| 1 | # Scalping Strategy |
| 2 | |
| 3 | Target small, frequent profits from minimal price movements on 1m-5m timeframes. |
| 4 | |
| 5 | ## Setup Conditions |
| 6 | |
| 7 | | Factor | Requirement | |
| 8 | | --- | --- | |
| 9 | | Data | Timestamped quotes/trades plus closed bars | |
| 10 | | Cost gate | Expected gross edge exceeds spread, fees, slippage, and adverse selection | |
| 11 | | Liquidity | Tested depth, order size, fill rate, and cancellation behavior | |
| 12 | | Risk | Hard per-trade and session loss limits from the portfolio mandate | |
| 13 | | Deployment | Positive held-out expectancy in the intended venue and session | |
| 14 | |
| 15 | ## Scalping Techniques |
| 16 | |
| 17 | ### 1. Momentum Scalping |
| 18 | |
| 19 | Enter on strong momentum candles on 1m, ride for small gain, exit immediately on momentum loss. |
| 20 | |
| 21 | ``` |
| 22 | get_indicators(indicator_code="rsi", symbol=<symbol>, exchange=<exchange>, interval="1m") |
| 23 | get_indicators(indicator_code="macd", symbol=<symbol>, exchange=<exchange>, interval="1m") |
| 24 | ``` |
| 25 | |
| 26 | Define an objective closed-bar momentum trigger and exit. RSI/MACD are correlated price transforms; retain them only if they improve held-out net results over a price-only baseline. |
| 27 | |
| 28 | ### 2. Level Scalping |
| 29 | |
| 30 | Quick bounces at key S/R levels with tight stops. |
| 31 | |
| 32 | ``` |
| 33 | get_candles_around_date(symbol=<symbol>, exchange=<exchange>, interval="5m", date=<date>) |
| 34 | ``` |
| 35 | |
| 36 | Identify levels on the context timeframe, define a numerical rejection on the execution timeframe, and place invalidation beyond the level plus expected stop slippage. Require the planned payoff to remain positive after costs. |
| 37 | |
| 38 | ### 3. Range Scalping |
| 39 | |
| 40 | Buy support, sell resistance within a defined micro-range. Repeat until range breaks. |
| 41 | |
| 42 | ``` |
| 43 | get_indicators(indicator_code="dmi", symbol=<symbol>, exchange=<exchange>, interval="5m") |
| 44 | ``` |
| 45 | |
| 46 | Use a calibrated range classifier; ADX alone does not confirm a micro-range. Stop applying the rule when the closed-bar invalidation or liquidity gate fails. |
| 47 | |
| 48 | ## Workflow |
| 49 | |
| 50 | ### 1. Confirm Direction on 5m |
| 51 | |
| 52 | ``` |
| 53 | get_indicators(indicator_code="ema", symbol=<symbol>, exchange=<exchange>, interval="5m") |
| 54 | get_indicators(indicator_code="dmi", symbol=<symbol>, exchange=<exchange>, interval="5m") |
| 55 | ``` |
| 56 | |
| 57 | Establish bias from higher timeframe before scalping on 1m. |
| 58 | |
| 59 | ### 2. Identify Setup on 1m |
| 60 | |
| 61 | ``` |
| 62 | get_candles_around_date(symbol=<symbol>, exchange=<exchange>, interval="1m", date=<date>) |
| 63 | get_indicators(indicator_code="rsi", symbol=<symbol>, exchange=<exchange>, interval="1m") |
| 64 | ``` |
| 65 | |
| 66 | Pick one technique (momentum, level, or range) based on current conditions. |
| 67 | |
| 68 | ### 3. Mark Key Levels |
| 69 | |
| 70 | ``` |
| 71 | draw_chart_analysis(action="create", drawing={ |
| 72 | "type": "support", |
| 73 | "points": [ |
| 74 | {"time": <touch_1>, "price": <level>}, |
| 75 | {"time": <touch_2>, "price": <level>} |
| 76 | ], |
| 77 | "options": {"text": "Scalp Level"} |
| 78 | }) |
| 79 | ``` |
| 80 | |
| 81 | ### 4. Report to Orchestrator |
| 82 | |
| 83 | Technique selected, timestamped quote, order type, expected fill, entry, invalidation, target, total cost estimate, capacity, and context-timeframe bias. |
| 84 | |
| 85 | ## Evidence and Validation |
| 86 | |
| 87 | - Treat the setup as a testable hypothesis, not a prediction. Define thresholds, entry, invalidation, and exit before evaluating outcomes. |
| 88 | - Calibrate on the same instrument, venue, session, and timeframe. Use closed candles and a held-out or walk-forward sample; record every variant tried. |
| 89 | - Include spread, fees, slippage, borrow or funding, partial fills, and latency. Reject the setup when net expectancy is not positive or depends on one narrow parameter. |
| 90 | - Return observed inputs, missing data, cost assumptions, entry, invalidation, exit, and a valid, watch, or no-trade status. |
| 91 | - Research basis: [Barber et al.](https://academic.oup.com/raps/article-pdf/10/1/61/31788119/raz006.pdf) found aggregate day-trader performance was negative and persistent profitability rare, making net-of-cost evidence and strict loss limits essential. |
| 92 | |
| 93 | ## Key Rules |
| 94 | |
| 95 | - Exclude scheduled event windows unless a separately tested event strategy and mandate apply. |
| 96 | - Reject markets and order sizes that fail the spread, depth, fill-rate, latency, or cost gate. |
| 97 | - Exit on the predeclared invalidation; do not widen risk after entry. |
| 98 | - Enforce the mandate's session loss and order-rate limits; pause on feed, clock, or execution anomalies. |
| 99 | - Compare context-aligned and context-agnostic variants rather than assuming alignment adds edge. |
| 100 | - Do not deploy from win rate alone; require positive net expectancy and stable tail losses. |
