Fundig Rate OI

# 🚀 [SHARED] Bitcoin Funding Rate + Open Interest Indicator - PineScript v6

## 📋 Summary
I've developed a **Bitcoin-specific** indicator that combines **Funding Rate** with **normalized Open Interest** for advanced futures analysis. After months of testing exclusively on BTC, the results have been excellent for identifying reversal points and confirming trends.

## 🎯 Why Bitcoin Only?

**Technical reasons:**
- BTC has the highest volume and liquidity in futures
- More consistent and reliable data
- Less manipulation than altcoins
- More stable correlation between FR and OI

**Problem it solves:**
- Traditional indicators only show one metric
- Difficult to correlate FR with BTC market volume/interest
- Lack of normalization makes OI hard to interpret
- Need for a tool specific to the king of cryptos

**Solution:**
✅ **Dynamic Funding Rate** optimized for BTC
✅ **Normalized Open Interest** (3 different methods)
✅ **Binance BTCUSDTPERP data** exclusively
✅ **Alert system** calibrated for BTC volatility
✅ **Real-time info table**

## 📊 How to Interpret Bitcoin Signals

### Funding Rate (Histogram):
- **FR > 0.1%:** BTC longs paying high → Possible short
- **FR < -0.1%:** BTC shorts paying high → Possible long
- **FR extreme (>0.5%):** High probability of BTC reversal
- **FR neutral (±0.05%):** Balanced market

### Open Interest (Blue line):
- **OI > 0.8 + high FR:** Many BTC longs trapped → Bearish
- **OI < 0.2 + low FR:** Short capitulation → Bullish
- **OI divergence:** BTC trend weakening

### Bitcoin-Specific Combinations:
1. **FR > 0.3% + OI > 0.85:** Imminent bearish reversal
2. **FR < -0.2% + OI < 0.15:** Probable bullish reversal
3. **FR oscillating + OI growing:** Accumulation before move

```

**Example 2 - Local Top (February 2024):**
```
Situation: BTC at ATH 73.8k
FR: +0.42% (desperate longs paying)

```

**Example 3 - Bullish Continuation:**
