UPDATE:
This Pine Script code is an indicator for TradingView that displays support, resistance, and OHLC (Open, High, Low, Close) data across various timeframes. The code is divided into two main sections: Support/Resistance and OHLC Data.
Support and Resistance:
Logic for Support and Resistance: The indicator draws support and resistance lines after 4 consecutive candles without forming new lows (for support) or new highs (for resistance). This means that a support or resistance level is created after 4 candles that don't set new extremes.
Support: When the last 3 candles have lower lows, and the current candle forms a higher low, the support level is set.
Resistance: When the last 3 candles have higher highs, and the current candle forms a lower high, the resistance level is set.
Drawing the Lines and Labels:
Once the support or resistance level is determined, a horizontal line is drawn that extends left and right from the candle.
Additionally, labels for support and resistance are shown if the corresponding settings are enabled. These labels appear at a distance from the line and display the current support or resistance value.
Deleting the Lines:
If the price falls below the support level or rises above the resistance level, the respective line is deleted. This means that the market has breached the support or resistance level, making the line invalid.
When the support or resistance line is breached, alerts can be triggered to notify the trader.
Alerts:
The script provides options to set alerts when a support or resistance line is created or broken. These alerts notify the trader when the price reaches an important level.
OHLC Data:
The code allows the display of the high, low, close, and open values of the last candles across different timeframes (hourly, daily, weekly, monthly).
Settings:
Options are available to show these values for the respective timeframes.
The user can also adjust the size of the labels.
Visualization: The indicator plots lines for the high, low, and close values for each timeframe and places labels showing the respective values.
In summary, the indicator provides a detailed view of support and resistance levels, which are based on a 4-candle logic, and displays important OHLC values across different timeframes. The indicator also allows setting alerts for specific price levels, so traders can quickly react to market movements.
