Adaptive Weight Price Oscillator -Aynet

# Adaptive Weight Price Oscillator (AWPO) - Aynet

## Core Components

### 1. Input Parameters
- `fastLength`: Period for the fast EMA calculation (default: 10)
- `slowLength`: Period for the slow EMA calculation (default: 21)
- `adaptiveLength`: Period for calculating volatility-based adaptation (default: 34)
- `smoothing`: Smoothing factor for the adaptive weight (default: 2)

### 2. Price and Weight Calculations

#### Median Price
The indicator uses median price as its base calculation:
```pine
medianPrice = (high + low) / 2
```

#### Volatility-Based Weight
The `getVolatilityRatio` function calculates a volatility ratio:
```pine
getVolatilityRatio(length) =>
std = ta.stdev(medianPrice, length)
ratio = std != 0 ? ta.ema(math.abs(ta.change(medianPrice)), length) / std : 0
math.max(math.min(ratio, 1), 0)
```
This function:
1. Calculates standard deviation of median price
2. Computes the ratio of EMA of price changes to standard deviation
3. Constrains the result between 0 and 1

### 3. AWPO Calculation
The main AWPO value is calculated as:
```pine
awpo = (fastMA - slowMA) * adaptiveWeight
```
Where:
- `fastMA`: EMA of median price using fast length
- `slowMA`: EMA of median price using slow length
- `adaptiveWeight`: Smoothed volatility ratio

## Signal Generation

### 1. Signal Line
- Calculated as an EMA of the AWPO with default length of 9
- Used for generating trading signals

### 2. Trading Signals
The indicator generates several types of signals:

#### Crossover Signals
- Buy signal: When AWPO crosses above the signal line
- Sell signal: When AWPO crosses below the signal line

#### Divergence Signals
- Bearish Divergence: Price makes higher high while AWPO makes lower high
- Bullish Divergence: Price makes lower low while AWPO makes higher low

## Visual Components

### 1. Main Plots
- AWPO line (green/red based on direction)
- Signal line (yellow)
- Zero line (gray, dotted)
- Overbought/Oversold levels (dotted lines)

### 2. Color Fills
- AWPO to Signal line fill (green/red)
- AWPO to Zero line fill (green/red)
- Overbought/Oversold zone fills

### 3. Trade Signals
- Triangle up/down shapes for buy/sell signals
- Diamond shapes for divergence signals

## Anti-Repainting Measures
The code includes measures to prevent repainting:
```pine
var float safe_awpo = na
if barstate.isconfirmed
safe_awpo := awpo
```
This ensures signals only appear on confirmed bars.

## Alert Conditions
The indicator includes two alert conditions:
1. AWPO crossing above signal line (buy)
2. AWPO crossing below signal line (sell)
