Multi-Timeframe Trend & S/R

This TradingView Pine Script indicator is designed to analyze market trends across multiple timeframes—4-hour, 1-hour, and 15-minute charts—to identify bullish and bearish trends, entry/exit points, and key support/resistance levels.

1. Inputs & Timeframe Selection
The script requests data from three different timeframes:

4-hour (240 min)
1-hour (60 min)
15-minute (15 min)
It processes moving averages, RSI values, and price action from these timeframes to determine trend strength and market direction.

2. Trend Analysis Using Moving Averages
A 50-period Simple Moving Average (SMA) is calculated for each timeframe.
If the 15-minute SMA is above the 1-hour SMA and the 1-hour SMA is above the 4-hour SMA, this indicates a strong bullish trend.
Conversely, if the 15-minute SMA is below the 1-hour SMA and the 1-hour SMA is below the 4-hour SMA, it signals a bearish trend.
3. Momentum Confirmation Using RSI (Relative Strength Index)
The RSI (14-period) is calculated for each timeframe.
If the 15-minute RSI is above 50, it supports a bullish trend.
If the 15-minute RSI is below 50, it confirms a bearish trend.
4. Entry & Exit Conditions
The script uses crossovers of moving averages for buy/sell signals:

Buy Signal (Long Entry):
When the 15-minute SMA crosses above the 1-hour SMA while confirming a bullish trend.
Sell Signal (Short Entry):
When the 15-minute SMA crosses below the 1-hour SMA while confirming a bearish trend.
Exit Conditions:
Exit Long: If the 15-minute SMA crosses below the 1-hour SMA.
Exit Short: If the 15-minute SMA crosses above the 1-hour SMA.
Buy signals are marked in green, sell signals in red, and exits in blue/orange.

5. Support & Resistance Levels
The script identifies key support and resistance levels for each timeframe:

Support Levels:
Lowest price over the last 50 bars for 4-hour, 1-hour, and 15-minute timeframes.
Resistance Levels:
Highest price over the last 50 bars for 4-hour, 1-hour, and 15-minute timeframes.
Each support and resistance level is plotted in different colors:

4-Hour Levels: Blue
1-Hour Levels: Green
15-Minute Levels: Purple
