Custom Indicator MT5

i need a custom indicator in mql5 syntax with arrows to point when to buy or sell at time frames M5 and M15. the bellow settings and criteria look into higher time frames to confirm entries. I need extra string to add symbols:

input string symbol2 = "DXY"; input string symbol3 = "US10Y";

i have made a very basic  sketch on chatgpt but it needs professional code work.

Additional Indicators:

5.     Moving Average Convergence Divergence (MACD): This can help to confirm the trend direction and momentum.

§  MACD Line: Difference between the 12-period and 26-period EMA.

§  Signal Line: 9-period EMA of the MACD Line.

§  Entry Criteria: Buy when the MACD Line crosses above the Signal Line, and sell when it crosses below.

6.     Bollinger Bands: These can be used to identify overbought and oversold conditions.

§  Entry Criteria: Buy when the price touches the lower band, and sell when it touches the upper band.

7.     Volume: Volume indicators can confirm the strength of a price move.

§  On-Balance Volume (OBV): Used to detect trend direction.

§  Entry Criteria: Confirm buy signals with increasing volume and sell signals with decreasing volume.

8.     Fibonacci Retracement Levels: These can be used to identify potential support and resistance levels.

§  Entry Criteria: Buy near the 38.2%, 50%, or 61.8% retracement levels during an uptrend and sell near these levels during a downtrend.

9.     Parabolic SAR: This can help to determine the direction of the trend and potential reversal points.

§  Entry Criteria: Buy when the Parabolic SAR moves below the price, and sell when it moves above the price.
