Using SPY and SPX to Confirm ES Trades
If you're trading ES without looking at SPY or SPX, you're handicapping yourself. ES doesn’t move in a vacuum — it’s tied directly to the S&P 500 index (SPX) and its ETF proxy (SPY). When these three aren’t aligned, your trade gets weak follow-through or fails outright. Here's how to use SPY and SPX as confirmation tools without overcomplicating them.
Why SPY and SPX Matter for ES
SPX is the actual S&P 500 index. ES is the futures market for it. SPY is the ETF tracking it. When all three move together, momentum is clean. When one lags or diverges, something’s off — usually liquidity or short-term rotation.
| Symbol | What It Represents | Use Case |
|---|---|---|
| ES | S&P 500 futures | Primary market to trade |
| SPX | S&P 500 index | Trend confirmation |
| SPY | ETF tracking the index | Retail-driven intraday sentiment |
How to Use SPY and SPX to Confirm ES Direction
1. Check if SPX Confirms the Trend
SPX moves cleaner than SPY because it’s not affected by ETF flows. If ES is pushing higher but SPX isn’t making higher highs, your ES long is weak. If ES breaks down but SPX doesn’t follow, expect chop or reversal.
2. Check SPY for Intraday Momentum
SPY reacts slightly differently because it's traded heavily by retail and funds. If SPY and ES are aligned during a trend push, continuation is likely. If SPY lags, your breakout can fail.

3. Watch for Divergences
Divergences aren't magic — they just show conflicting order flow. Examples:
- ES makes a higher high, SPY doesn’t → weak breakout
- ES makes a lower low, SPX holds steady → failed breakdown coming
How SPY and SPX Help With Timing
During trend days, SPX leads. During choppy days, SPY leads. If you see all three aligning at a key level like VWAP or prior day high/low, that’s a high-probability continuation or reversal point.
If you're not using VWAP and session levels yet, check Session Highs/Lows & VWAP.
Final Takeaway
SPY and SPX aren’t optional if you want high-quality ES trades. They show you when the market is aligned, when something’s off, and when your trade has real backing. Use them as confirmation tools — not predictors — and your entries get cleaner instantly.
