Aroon Buy & Sell with Customizable Candle Pattern Filter

Sure! Here's a description of how the script works without the code:

### Overview:

This trading strategy combines the **Aroon indicator** and **candlestick pattern recognition** to generate buy and sell signals. It allows for a more customizable approach by enabling you to filter signals based on the direction of a trend (identified by the Aroon indicator) and specific candlestick patterns that are often seen as indicators of potential reversals or continuation in the market.

### Key Components:

1. **Aroon Indicator**:

* **Aroon Up and Aroon Down** are calculated over a 14-period window. The Aroon Up shows how recently the highest high occurred, while Aroon Down shows how recently the lowest low occurred.
* A crossover between the Aroon Up and Aroon Down lines indicates a change in market trend. When the Aroon Up crosses above the Aroon Down, it's a signal of an uptrend, and when the Aroon Down crosses above the Aroon Up, it's a signal of a downtrend.
* The strategy uses **5-minute** Aroon data to track the overall trend and **1-minute** Aroon data to refine entry signals.

2. **Candlestick Pattern Filters**:
The script allows you to select and use various candlestick patterns to filter the signals:

* **Bullish Engulfing**: A pattern where a bullish candle completely engulfs the previous bearish candle.
* **Bearish Engulfing**: A pattern where a bearish candle completely engulfs the previous bullish candle.
* **Pin Bar**: A candlestick with a small body and a long tail, indicating potential reversal.
* **Doji**: A candlestick with a very small body, showing indecision in the market.
* You can toggle each of these patterns on or off based on your preference.

3. **Signal Generation**:

* **Buy Signal**: A buy signal is triggered when the market is in a bullish trend (as indicated by the Aroon Up crossing over the Aroon Down on the 5-minute chart), the Aroon Down on the 1-minute chart is at 100% (suggesting a low moment for entry), and a valid candlestick pattern (like Bullish Engulfing, Pin Bar, or Doji) occurs.
* **Sell Signal**: A sell signal is triggered when the market is in a bearish trend (as indicated by the Aroon Down crossing over the Aroon Up on the 5-minute chart), the Aroon Up on the 1-minute chart is at 100% (suggesting a potential reversal point), and a valid candlestick pattern (like Bearish Engulfing, Pin Bar, or Doji) occurs.

4. **Cooldown Period**:

* The strategy includes a **cooldown** mechanism to prevent multiple signals from being triggered in a very short period. This helps avoid false signals and ensures that only significant trends or pattern formations are considered for trades.

5. **Signal Plotting**:

* **Buy Signals** are displayed as green "BUY" labels below the price bars.
* **Sell Signals** are displayed as red "SELL" labels above the price bars.

6. **Alerts**:

* Alerts are set up to notify the user when a buy or sell signal is triggered. This can be useful for traders who prefer to be alerted when a valid setup is detected.

### Customization:

* The user can customize which candlestick patterns they want to use in the strategy by turning them on or off.
* The user can also adjust the Aroon settings and other parameters, allowing for flexibility in adapting the strategy to different market conditions and personal preferences.

### Summary:

This strategy blends trend-following (via Aroon) with reversal/continuation signals from candlestick patterns, providing traders with a way to fine-tune their entries and exits based on both trend strength and price action patterns. It aims to reduce noise and filter out weak signals by combining these elements.
