// === EXPLANATION OF CONCEPTS ===
// Deep Knowledge of Market from AI:
// This indicator is based on a powerful, yet often misunderstood, concept: divergence.
// While standard divergence signals a potential trend reversal, hidden divergence signals a
// continuation of the prevailing trend. This is crucial for traders who want to capitalize
// on the momentum of a move rather than trying to catch tops and bottoms.

// Hidden Bullish Divergence: Occurs in an uptrend when price makes a higher low, but the
// RSI makes a lower low. This suggests that while there was a brief period of weakness, the
// underlying buying pressure is returning to push the trend higher. It’s a "re-energizing"
// of the bullish momentum.

// Hidden Bearish Divergence: Occurs in a downtrend when price makes a lower high, but the
// RSI makes a higher high. This indicates that while the sellers paused, the underlying
// selling pressure remains strong and is likely to continue pushing the price down. It's a
// subtle signal that the bears are regaining control.

// Combining Divergence with S/R: The true power of this indicator comes from its
// "confluence" principle. A divergence signal alone can be noisy. By requiring it to occur
// at a key support or resistance level (identified using pivot points), we are filtering
// out weaker signals and only focusing on high-probability setups where the market is
// likely to respect a previous area of interest. This tells us that not only is the trend
// likely to continue, but it is doing so from a strategic, well-defined point on the chart.

// Dynamic Take-Profit Targets: The take-profit targets are based on the Average True Range (ATR).
// ATR is a measure of market volatility. Using it to set targets ensures that your profit
// levels are dynamic and adapt to current market conditions. In a volatile market, your
// targets will be wider, while in a calm market, they will be tighter, helping you avoid
// unrealistic expectations and improving your risk management.
