mean reversion Spread Z-Score

Your main "actor" is the Blue Line 🔵 (the Z-Score). It tells you if your spread is "expensive" or "cheap" compared to its average.
The other lines are your action zones.
Here is how to read the signals:
Scenario 1: SELL the Spread (The spread is TOO EXPENSIVE)
• ENTRY Signal: The Blue Line 🔵 moves up and crosses the Red Line 🔴 (at +1.8).
• Meaning: MNQ has become far too expensive compared to MES. The rubber band is stretched too far upwards.
• Your Action (Sell):
• ✅ SELL MNQ
• ✅ BUY MES
• EXIT Signal: The Blue Line 🔵 comes back down and crosses the Dotted Red Line (at +0.5).
• Meaning: The rubber band is back to normal. It's time to take your profits.
• Your Action (Close):
• ✅ BUY BACK your MNQ
• ✅ SELL your MES
Scenario 2: BUY the Spread (The spread is TOO CHEAP)
• ENTRY Signal: The Blue Line 🔵 moves down and crosses the Green Line 🟢 (at -1.8).
• Meaning: MNQ has become far too cheap compared to MES. The rubber band is stretched too far downwards.
• Your Action (Buy):
• ✅ BUY MNQ
• ✅ SELL MES
• EXIT Signal: The Blue Line 🔵 moves back up and crosses the Dotted Green Line (at -0.5).
• Meaning: The rubber band is back to normal. It's time to take your profits.
• Your Action (Close):
• ✅ SELL your MNQ
• ✅ BUY BACK your MES
In summary:
• Blue Line 🔵 touches Red Line 🔴 = Sell the spread.
• Blue Line 🔵 touches Green Line 🟢 = Buy the spread.
