## 1. Technical Analysis Indicators Reference

### RSI (Relative Strength Index)
```
Formula: RSI = 100 - (100 / (1 + RS))
Where:  RS = Average Gain / Average Loss over N periods (default N = 14)

Step-by-step calculation:
  1. For each period, compute change = Close(t) - Close(t-1)
  2. Gains = max(change, 0), Losses = abs(min(change, 0))
  3. First average: simple mean of first 14 gains/losses
  4. Subsequent: AvgGain = (PrevAvgGain * 13 + CurrentGain) / 14  (Wilder smoothing)
  5. RS = AvgGain / AvgLoss
  6. RSI = 100 - (100 / (1 + RS))

Worked example (14-period):
  Avg Gain over 14 periods = 1.02
  Avg Loss over 14 periods = 0.68
  RS = 1.02 / 0.68 = 1.50
  RSI = 100 - (100 / (1 + 1.50)) = 100 - 40 = 60.0
```

**Interpretation:**
- RSI < 30: Oversold territory (potential buy signal)
- RSI > 70: Overbought territory (potential sell signal)
- RSI = 50: Neutral, price momentum balanced

**Advanced RSI Signals:**
| Signal | Description | Strength |
|--------|-------------|----------|
| Bearish divergence | Price makes new high, RSI makes lower high | Strong reversal warning |
| Bullish divergence | Price makes new low, RSI makes higher low | Strong reversal warning |
| Bullish failure swing | RSI drops below 30, bounces, pulls back above 30, breaks prior RSI high | Very strong buy |
| Bearish failure swing | RSI rises above 70, drops, bounces below 70, breaks prior RSI low | Very strong sell |
| Range shift | RSI oscillates 40-80 in uptrend, 20-60 in downtrend | Trend confirmation |

**Best practices:** Never use RSI as a sole signal. Combine with trend direction (moving averages) and volume. In strong trends, RSI can stay overbought/oversold for extended periods.

### MACD (Moving Average Convergence Divergence)
```
MACD Line   = EMA(12) - EMA(26)
Signal Line = EMA(9) of MACD Line
Histogram   = MACD Line - Signal Line
