Buffer values

[Jakey]

Hello,

I'm working with a developer to create a mt4 indicator that reads buffer values on the chart saved by 2 other indicators and uses those values to determine when a trade alert should be given.

I want to use the iCustom() function to reference values stored from the other two indicators on the chart. Then define the logic to determine when a trade alert should be given based on the values retrieved from the other indicators.

The 3 indicators used are "7 Combo", "ZZSRT" and "MA Angle".

ZZSRT and MA Angle store values and 7 Combo references the values stored. 

I do not want to call the ZZSRT and MA Angle internally from within the 7 combo indicator, so if a change is made to the parameters of the ZZSRT or MA Angle, I will need to reload the 7 Combo indicator. 

The developer is saying "I have tried it, but it did not work on our side, it is not a realistic approach."

I'm having a hard time believing him but want to check with ya'll first. 

Please let me know your thoughts and thank you for your help, I appreciate it.

Here is the sample code I sent over. 

7 Combo reads buffer values from ZZSRT and MA Angle and adapts to changes in buffer numbers for ZZSRT and MA Angle:

// Variables to store initial buffer values
double initialMAAngleBuffer[];
double initialZZSRTBuffer[];

// Flag to indicate changes
bool bufferValuesChanged = false;

// OnChartEvent handler
void OnChartEvent(const int id,
                  const long &lparam,
                  const double &dparam,
                  const string &sparam)
{
    if (id == CHARTEVENT_OBJECT_CREATE && sparam == "7 Combo") {
        // Opening event of 7 Combo properties window
        CaptureInitialBufferValues();
    } else if (id == CHARTEVENT_OBJECT_DELETE && sparam == "7 Combo" && dparam == OBJPROP_XDISTANCE) {
        // Closing event of 7 Combo properties window by clicking "OK"
        CheckForBufferChanges();
    }
}

// Function to capture initial buffer values
void CaptureInitialBufferValues()
{
    // Capture initial buffer values of MA Angle and ZZSRT
    initialMAAngleBuffer[0] = iCustom(Symbol(), PERIOD_CURRENT, "MA Angle", 0, 0);
    initialZZSRTBuffer[0] = iCustom(Symbol(), PERIOD_CURRENT, "ZZSRT", 0, 0);
}

// Function to check for buffer changes
void CheckForBufferChanges()
{
    // Check current buffer values of MA Angle and ZZSRT
    double currentMAAngleBuffer = iCustom(Symbol(), PERIOD_CURRENT, "MA Angle", 0, 0);
    double currentZZSRTBuffer = iCustom(Symbol(), PERIOD_CURRENT, "ZZSRT", 0, 0);
    
    // Compare with initial values
    if (currentMAAngleBuffer != initialMAAngleBuffer[0] || currentZZSRTBuffer != initialZZSRTBuffer[0]) {
        // Buffer values have changed
        bufferValuesChanged = true;
        
        // Trigger necessary actions to adapt 7 Combo indicator
        AdaptIndicator7Combo();
    }
}

// Function to adapt 7 Combo indicator
void AdaptIndicator7Combo()
{
    // Implement logic to adapt 7 Combo indicator to buffer value changes
}

Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

Next time, post in the correct place. I have moved this thread.

Hi William,

My mistake and my apologies, thank you for moving it to the correct section. 

Thanks,

Jake
