Add Buffers and Dots to MQL4
Prompt
You are provided with existing MQL4 code that implements certain indicator functionality. Your task is to enhance this code by adding new buffers and displaying additional dots on the chart as specified below. **Requirements:** 1. **Maintain the existing code and all current functionality without removal or alteration unless necessary for integration.** 2. **Add buffer index values to appear in the Data Window:** - Add a buffer for a green dot value. 3. **Add new dot buffers and display dots for Bullish FVG High and Bearish FVG Low:** - After a Bullish FVG confirmation, identify the Bullish FVG High as the low of the last candle (the third candle) involved in the FVG formation. Mark this point with a blue dot on the chart. - After a Bearish FVG confirmation, identify the Bearish FVG Low as the low of the last candle (the third candle). Mark this point with a red dot on the chart. **Additional details:** - Use separate buffers for each dot type (green, blue, red). - Ensure these buffers correspond to properly indexed candles so the dots align visually on the chart. - The values in the buffers should be set in a manner that they appear correctly in the Data Window and on the price chart. # Steps 1. Review the existing MQL4 code to understand current buffers and how dots are plotted. 2. Define new buffers for green dot, blue dot (Bullish FVG High), and red dot (Bearish FVG Low). 3. Update the `OnInit` function or equivalent to allocate buffers and set their properties. 4. In the calculation function (e.g., `OnCalculate`), implement logic to: - Detect Bullish and Bearish FVG confirmation. - Mark the Bullish FVG High with a blue dot at the low of the last candle. - Mark the Bearish FVG Low with a red dot similarly. - Add the green dot value to its buffer at the appropriate candle. 5. Ensure all buffer values are properly indexed, and values for candles without dots are set to `EMPTY_VALUE`. 6. Confirm that the Data Window displays the new buffers and their values. # Output Format Provide the complete, updated MQL4 code with the added buffers and dot plotting logic integrated. The code must compile and run within MetaTrader 4, showing the new green, blue, and red dots correctly aligned with their respective candle points and displaying buffer values in the Data Window.
