Strategy — EMA10 × SMA50 Crossover

Quick Info

What this signal is
This is a fast momentum crossover: the 10-day Exponential Moving Average (EMA10) crosses above or below the 50-day Simple Moving Average (SMA50).

• EMA10 > SMA50 → Buy bias — short-term trend overtakes the medium trend (early bullish inflection).
• EMA10 < SMA50 → Sell bias — short-term trend rolls under (early warning of weakness).

Because EMA reacts faster than SMA, this setup can catch early trend changes, but it’s more prone to whipsaws in sideways markets. Use confirmations and risk controls.

Extended Guide (Deeper Dive)

1) Signal Definition

• Bullish cross (Buy bias): EMA10 crosses above SMA50 and price closes above the crossover zone.
• Bearish cross (Sell bias): EMA10 crosses below SMA50 and price closes below the zone.
• Compared with SMA20 × SMA50, this is earlier/faster, but noisier.

EMA vs SMA
EMA gives more weight to recent prices, responding quicker to momentum shifts. This can improve entry timeliness at the cost of higher false signals in chop.

2) Entry & Exit Rules (reference template)

Baseline long entry

1. Trigger: EMA10 crosses above SMA50 (today or within last 1–2 sessions).
2. Confirmations (pick 1–3):
   • Close above both MAs and above a recent swing high.
   • RSI(14) > 50–55 (momentum positive).
   • Volume thrust: day’s volume ≥ 1.5× 20-day average.
   • ADX(14) > 20 (a trend actually exists).
   • Trend filter: price above 200-SMA.
3. Risk: Initial stop below the crossover zone or most recent swing low (e.g., 1.5–2.5× ATR(14)).
4. Position size: Risk a fixed % of equity (e.g., 0.5–1.0% per trade).
5. Exits (choose one or combine):
   • Momentum fade: close back below SMA50 or RSI < 45.
   • Trailing: ATR/Chandelier stop or 10–20% trailing stop.
   • Target-based: scale at +1R and +2R.

Baseline short mirrors the above with inverted conditions.

3) When It Works Best / Struggles

Works best

• Early trend transitions (post-base/breakout) where speed matters.
• Liquid names and broadening sector breadth (follow-through).

Struggles

• Sideways/choppy ranges where price oscillates around MAs.
• Event risk (earnings, guidance, regulatory) that overwhelms technicals.

4) Whipsaw Management (practical options)

• Trend filter: Take bullish crosses only above 200-SMA (and vice-versa).
• Persistence rule: Require 2 consecutive closes confirming the cross.
• Retest entry: Prefer the first pullback to the crossover zone after the cross.
• Breadth/volatility guard: Avoid entries when VIX is spiking or sector breadth is deteriorating.
• Quality score (0–5): Add 1 point each for: price > 200-SMA, RSI > 55, ADX > 20, volume ≥ 1.5×, breakout close > recent swing.

5) Timeframe, Sizing & Portfolio Controls

• Timeframe: Daily charts; swing horizon days–weeks.
• Risk per trade: Small and steady (e.g., 0.5–1.0%).
• Open risk cap: Keep aggregate open risk ≤ 5% of equity.
• Correlation: Limit exposure to highly correlated names/sectors.

6) Variations to Test

• EMA10 × EMA30: even faster, highest sensitivity.
• EMA10 × SMA50 + RSI band (55–70): momentum overlay to reduce noise.
• “Fresh cross + first pullback” entry: improves price/stop asymmetry.
• Time-of-week filter: require signals on non-Friday closes to dodge weekend gaps (optional).

7) Checklists

Bullish crossover checklist

• EMA10 just crossed above SMA50 (≤ 2 sessions ago)
• Close above both MAs; RSI > 50–55
• Volume ≥ 1.5× 20-day or ADX > 20
• Price above 200-SMA (preferred)
• Stop and position size defined (ATR-based or swing low)

Bearish crossover checklist (inverse)

8) Backtest Notes (how we evaluate)

• Universe: Liquid mid/large caps; ETFs allowed.
• Execution: Next-day open after signal; include realistic slippage.
• Metrics: Win rate, profit factor, max drawdown, CAGR, average hold.
• A/B filters: 200-SMA trend, RSI > 50–55, volume thrust, ADX > 20.
• Exit logic: Close back through SMA50 vs ATR trail — compare robustness.

(Historical performance varies by universe and regime; forward picks are rules-based, not guarantees.)

10) FAQ

Is this a recommendation?
No. It’s a technical signal for education and research. Manage risk independently.

Should I trade through earnings?
Generally avoid new entries immediately before earnings unless specifically labeled as event-risk trades.

Can I run it intraday?
Possible, but noise increases sharply. Our baseline is the daily timeframe.

Crypto/FX/ETFs?
Yes—liquidity and session behavior matter. Test first.
