I am starting out in using the MDK. I would like to find out that did anyone try to draw a swing line using MDK. Something similar to the ZigZag function. Thank you

Returning values for these sort of lines is easy. Iterate through the chart twice, the first is to define the points, then the second is to fill in the values between the points found in the first pass (you can also do it one pass using internal loops).

Modified ZZ (snippet) Code:
for(int i=l_iMinRecords; i<=l_iMaxRecords; i++)
{
l_lfHigh = a_psDataRec->sHigh.pfValue[ i ];
l_lfLow = a_psDataRec->sLow.pfValue[ i ];
l_lfRetracement = fabs(l_psRetracement->pfValue[ i ]);
if(i==l_iMinRecords)
{
l_lfLastPeakPrice = l_lfHigh;
l_lfLastTroughPrice = l_lfLow;
l_iLastPeakIndex = i;
l_iLastTroughIndex = i;
}
else
{
if(l_iDirection!=UP)
{
if(l_iMethod==0)//pct
l_lfTriggerPrice = l_lfLastTroughPrice * (1.0f + l_lfRetracement);
else
l_lfTriggerPrice = l_lfLastTroughPrice + l_lfRetracement;
}
else
{
if(l_iMethod==0)//pct
l_lfTriggerPrice = l_lfLastPeakPrice * (1.0f - l_lfRetracement);
else
l_lfTriggerPrice = l_lfLastPeakPrice - l_lfRetracement;
}
if(l_iDirection != UP && l_lfHigh > l_lfTriggerPrice) //retracement forms a new TROUGH
{
l_lfLastPeakPrice = l_lfHigh;
l_iLastPeakIndex = i;
l_iDirection = UP;
}
else if(l_iDirection != DN && l_lfLow < l_lfTriggerPrice) // retracement forms a new PEAK
{
l_lfLastTroughPrice = l_lfLow;
l_iLastTroughIndex = i;
l_iDirection = DN;
}
else if(l_iDirection == UP && l_lfHigh>=l_lfLastPeakPrice) // continuation of the uptrend following a recent trough
{
l_lfLastPeakPrice = l_lfHigh;
l_iLastPeakIndex = i;
l_iDirection = UP;
}
else if(l_iDirection == DN && l_lfLow<=l_lfLastTroughPrice) //continuation of downtrend following a recent peak
{
l_lfLastTroughPrice = l_lfLow;
l_iLastTroughIndex = i;
l_iDirection = DN;
}
}
{... lots more to do here ...}
}
