MT4 MACD RSI Strategy

Create a MetaTrader 4 (MT4) custom indicator implementing a trading strategy with these requirements:

1. Use MACD with settings (48, 104, 36) to detect MACD crossing the signal line in the direction of the current trend.
2. Use MACD with settings (12, 26, 9) to detect the MACD crossing over the zero line in the direction of the trend.
3. Detect crossing events between a 15-period and 30-period moving average to confirm trend direction.
4. Identify hidden divergence signals on the MACD with settings (3, 6, 2).

Additionally, the indicator must display the current levels of the RSI and MACD on the chart for user reference.

Ensure the indicator only signals trades when all the above conditions are simultaneously met.

Implement robust error handling and comprehensive logging to record all executed trades and any runtime issues.

# Steps

- Calculate MACD and Signal line values for the specified settings.
- Detect crossovers and zero line crossings aligned with trend direction.
- Calculate 15 and 30 period moving averages and find their crossover points.
- Analyze MACD with (3,6,2) to detect hidden divergences.
- Calculate RSI and display its level on the chart.
- Display MACD level values on the chart.
- Verify all conditions before signaling a trade.
- Log information about trade signals and errors.

# Output Format

Provide the full MT4 indicator source code in MQL4 (.mq4) format including comments for clarity.

# Notes

- The trend direction can be determined based on moving average slopes or price action around MAs.
- Hidden divergence detection should consider typical divergence rules where price makes higher lows/lows while indicator makes lower lows/higher lows accordingly.
- Ensure logging does not degrade performance and includes timestamps.
