Cum_Delta_Candles.PNG

There seems to be no interest in helping me with my code, so I thought I would print the code I'm trying to alter.

Before everybody starts to copy the code I need to tell you that its just a shell for plotting the custom Delta indicator as ohlc candles in a separate window, thus making it a Cumulative Delta Volume indicator. And no I cant give out the Custom Delta indicator that's in the code.

I'm trying to make 2 things with this code, first make it start over from 0 every day and second calculate and plot a moving average of the candles in the code.
But I'm having problems with both. Its easy to just drop a moving average over the indicator on chart, but I need the buffer for it.

Any ideas would be welcome, and yes I have made efforts in making it work but I have failed every time.

Here is the original code:

Code: Select all

               
#property indicator_separate_window
#property indicator_buffers 5
#property indicator_plots   1
#property indicator_type1   DRAW_COLOR_CANDLES
#property indicator_color1  clrGreen, clrCrimson
#property indicator_label1  "Delta Open;Delta High;Delta Low;Delta Close"

// Indicator buffers
double ExtOBuffer[];
double ExtHBuffer[];
double ExtLBuffer[];
double ExtCBuffer[];
double ExtColorBuffer[];

// Delta buffers
double DeltaBuf[];
double BuyBuf[];
double SellBuf[];

input datetime inpHistoryDate=D'2022.01.01'; 

void OnInit()
{
    SetIndexBuffer(0, ExtOBuffer, INDICATOR_DATA);
    SetIndexBuffer(1, ExtHBuffer, INDICATOR_DATA);
    SetIndexBuffer(2, ExtLBuffer, INDICATOR_DATA);
    SetIndexBuffer(3, ExtCBuffer, INDICATOR_DATA);
    SetIndexBuffer(4, ExtColorBuffer, INDICATOR_COLOR_INDEX);

}

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
{
    int Delta;

    Delta = iCustom(NULL, PERIOD_CURRENT,"Delta_Indicator",inpHistoryDate); //Delta_Close
    if  (CopyBuffer(Delta, 0, 0, rates_total, DeltaBuf) != rates_total) return 0;    
    
    Delta = iCustom(NULL, PERIOD_CURRENT,"Delta_Indicator",inpHistoryDate); //Delta_Buy
    if  (CopyBuffer(Delta, 2, 0, rates_total, BuyBuf) != rates_total) return 0;

    Delta = iCustom(NULL, PERIOD_CURRENT,"Delta_Indicator",inpHistoryDate); //Delta_Sell
    if  (CopyBuffer(Delta, 3, 0, rates_total, SellBuf) != rates_total) return 0;

    // Preliminary calculations.
    int limit;
    if (prev_calculated <= 1)
    {
        // Set the first candle.
        ExtLBuffer[0] = 0;
        ExtHBuffer[0] = 0;
        ExtOBuffer[0] = 0;
        ExtCBuffer[0] = 0;
        limit = 1;
    }
    else limit = prev_calculated - 1;

    // The main loop of calculations.
    for (int i = limit; i < rates_total; i++)
    {
            ExtOBuffer[i] = ExtCBuffer[i-1];
            ExtLBuffer[i] = ExtCBuffer[i-1];
            ExtHBuffer[i] = ExtCBuffer[i-1];
            ExtCBuffer[i] = ExtCBuffer[i-1];
            
        if (BuyBuf[i] - SellBuf[i] < 0)
        {
            ExtOBuffer[i] = ExtCBuffer[i-1];
            ExtLBuffer[i] = ExtCBuffer[i-1]-DeltaBuf[i];
            ExtHBuffer[i] = ExtCBuffer[i-1];
            ExtCBuffer[i] = ExtCBuffer[i-1]-DeltaBuf[i];
            
            ExtColorBuffer[i] = 1.0;
        }

        else if (BuyBuf[i] - SellBuf[i] > 0)
        {
            ExtOBuffer[i] = ExtCBuffer[i-1];
            ExtLBuffer[i] = ExtCBuffer[i-1];
            ExtHBuffer[i] = ExtCBuffer[i-1]+DeltaBuf[i];
            ExtCBuffer[i] = ExtCBuffer[i-1]+DeltaBuf[i];
            
            ExtColorBuffer[i] = 0.0;
        }
    }

    return rates_total;
}
//+------------------------------------------------------------------+

here is how it looks, the problem is it just adds the delta from previous candle and so on.
