Adaptive Support & Resistance Pro with EMA Momentum Filter
## Description
This indicator is an advanced tool designed to identify adaptive Support and Resistance (S/R) zones and combine them with an Exponential Moving Average (EMA) momentum filter. Unlike static S/R lines, this script uses a combination of momentum oscillators and dynamic pivot calculations to find high-probability reversal zones on higher or current timeframes.
The core philosophy of this indicator is to prevent "knife-catching." Instead of firing a signal immediately when a support or resistance level is formed, it waits for the price to confirm a change in momentum by crossing the EMA line in the direction of the trade.

## How It Works (Under the Hood)
### 1. Support & Resistance Detection
The script uses a multi-layered filter to detect true pivot points:
* **Legacy RSI & Modified RSI:** It evaluates overbought (>75) and oversold (<25) conditions using a 9-period Relative Strength Index.
* **Chande Momentum Oscillator (CMO) based on HMA:** It applies a 1-period CMO logic over Hull Moving Averages (HMA 5 and HMA 12) to detect immediate shifts in market velocity.
* **Close Pivots:** It uses deviation-free highest/lowest calculations (`ta.highest` and `ta.lowest`) combined with `ta.valuewhen` to fetch precise structural levels.
A **Support Zone** is formed only when the RSI is oversold, the CMO shows an upward momentum shift (>50), and a local low pivot is confirmed.
A **Resistance Zone** is formed when the RSI is overbought, the CMO shows a downward shift (<-50), and a local high pivot is confirmed.
### 2. S/R Timeframe Flexibility
Through the `request.security` function, users can plot these adaptive levels from higher timeframes (HTF) onto their current chart. To prevent **repainting** and back-shifting signals, the script strictly uses `barmerge.lookahead_off`.
### 3. EMA Momentum Trigger (The Confirmation Filter)
To filter out false breakouts and premature entries during heavy trend extensions, an EMA filter is introduced:
* **BUY Signal:** Triggered only when a new Support level has been established AND the price successfully closes above the EMA (`ta.crossover`).
* **SELL Signal:** Triggered only when a new Resistance level has been established AND the price successfully closes below the EMA (`ta.crossunder`).
**Strict Discipline:** The script uses an internal state machine (`waitForBuyBreak` / `waitForSellBreak`) ensuring that **only ONE signal** is fired per newly created S/R level. This completely eliminates the "whipsaw" effect (multiple false signals) when the price is consolidating or chopping around the moving average.

## Settings & Customization
* **Line Width / Colors:** Fully customize the visual thickness and color styling of your Support and Resistance zones.
* **S/R Timeframe:** Leave it blank for the current chart timeframe, or select higher timeframes (e.g., 4H or 1D) for macro level analysis.
* **Enable EMA Filter:** Toggle this option ON to use the momentum confirmation logic, or OFF to see signals immediately upon S/R level creation.
* **EMA Length:** Adjust the period of the confirmation line (Default is 50, but can be set to 20 for faster entries or 200 for macro trend-following).

## Alerts
The script includes three built-in alert conditions for automation:
1. `New S/R line` - Triggers whenever a new support or resistance level is plotted.
2. `BUY Signal` - Triggers when the EMA crossover confirms the support bounce.
3. `SELL Signal` - Triggers when the EMA crossunder confirms the resistance rejection.
## Disclaimer
This indicator is meant for educational and analytical purposes only. Past performance does not guarantee future results. Always practice proper risk management.
