How to solve the warning: "possible loss of data due to type conversion" in MQL5

I wrote this sample code for learning purposes but I can't seem to solve the warning message of "possible loss of data due to type conversion".

I have tried to search online but I can't seem to find a solution on how to pass the value of the MQL5 built-in functions without getting this warning.

The iAMA built-in function of MQL5 returns an integer and this integer is getting assigned to a variable of type integer (as shown in the sample code below). I am not sure why there is a data loss warning if both of them are integers.

Note: The code is compiling and running well but for educational purposes, I would like to understand how to solve this warning message.

Your help will be much appreciated!

Here is the code:

    return(INIT_SUCCEEDED);

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],

{
    if(rates_total < ama_period)
    {
        return(0);
    }

//--- Troubleshooting: Data Calculation
    int calculated = BarsCalculated(ama_buffer_handle);
    if(calculated < rates_total)
    {
        Print("Not all data of ama_buffer_handle is calculated (", calculated, " bars). Error ", GetLastError());
        return(0);
    }

//--- Troubleshooting: Data Copying
    int to_copy;
    if(prev_calculated > rates_total || prev_calculated < 0)
    {
        to_copy = rates_total;
    }
    else
    {
        to_copy = rates_total - prev_calculated;
        if(prev_calculated > 0)
        {
            to_copy++;
        }
    }

//--- Copy & Validate Buffers
    if(CopyBuffer(ama_buffer_handle, 0, 0, to_copy, ama_buffer) <= 0)
    {
        Print("getting ama_buffer_handle is failed! Error ", GetLastError());
        return(0);
    }
  
    if(IsStopped())
    {
        return(0);
    }

    return(rates_total);
}

After reviewing back the documentation, I found out that I need to pass an ENUM_APPLIED_PRICE to the iAMA function instead of a double variable. That resolves the problem.

As in: ENUM_APPLIED_PRICE ama_src = PRICE_MEDIAN;
