EMA Slope First Flip Signal
1. EMA Calculation:
It calculates 4 Exponential Moving Averages:
EMA 5 – very fast (captures short-term moves)
EMA 9 – fast
EMA 21 – medium
EMA 50 – long-term trend
2. Slope Calculation:
It finds the slope of each EMA using:
pinescript
Copy
Edit
slopeX = emaX - emaX[1]
This checks if the EMA is rising (slope > 0) or falling (slope < 0).
3. Trend Condition:
Buy condition: All 4 EMA slopes must be positive
Sell condition: All 4 EMA slopes must be negative
4. First Signal Logic:
It only flashes a signal when the direction changes.
For example:
If EMAs were not all rising before, but now all are → BUY
If EMAs were not all falling before, but now all are → SELL
Prevents repeated signals during the same trend.
5. Safe Boolean Handling:
Uses bool(condition[1]) to access previous state without error
Avoids using nz() or na() on booleans (which causes errors)
📈 What You See on Chart:
✅ Green "BUY" label below candle when all EMA slopes turn positive for the first time
❌ Red "SELL" label above candle when all EMA slopes turn negative for the first time
🔄 No duplicate signals in the same direction — only on reversal
