LSMA Question

Trying to pin point when downward trend stops and upward trend begins.

.

Here's the LSMA code:

string FoundColor, ArrowUpA;

//---- initialization done

return(0);
}

int start()

{ Draw4HowLong = Bars-Rperiod - 5;
length = Rperiod;
loopbegin = Draw4HowLong - length - 1;



for(shift = loopbegin; shift >= 0; shift--)

{
sum[1] = 0;

for(i = length; i >= 1 ; i--)

{
lengthvar = length + 1;
lengthvar /= 3; //Dividing the y variable(lengthvar) by x(3) y /= x;
tmp = 0;
tmp = ( i - lengthvar)*Close[length-i+shift];
sum[1]+=tmp; //Adding x(0) to the y variable(tmp) y += x;
}

wt[shift] = sum[1]*6/(length*(length+1));



//========== COLOR CODING ===========================================

ExtMapBuffer3[shift] = wt[shift]; //White

ExtMapBuffer2[shift] = wt[shift]; //Lime

ExtMapBuffer1[shift] = wt[shift]; //Red

if (wt[shift+1] > wt[shift])

{
CNT[1] = 2;
ExtMapBuffer2[shift+1] = EMPTY_VALUE;


}

if (wt[shift+1] < wt[shift])

{
CNT[1] = 1;
ExtMapBuffer1[shift+1] = EMPTY_VALUE;

}

else

{
CNT[1] = 3;
ExtMapBuffer1[shift+1]=CLR_NONE; //EMPTY_VALUE;
ExtMapBuffer2[shift+1]=CLR_NONE; //EMPTY_VALUE;


}

}

return(0);
}

I created another buffer (#5) as a way to capture a val at the time of each "if statement" which should be each of the colors of the LSMA. I set CNT[1] to 1 for RED, 2 for LIME and 3 for WHITE.

.

But, with all my attempts to bring this value into my EA;

.

.

double LSMA5 = iCustom(NULL,0,"LSMA",5,0); //---- LSMA Buffer 5

Alert("LSMA5 = " + LSMA5);

.

.

All I get is;

.

Alert: LSMA5 = 2147483647.00000000

.

.

Can someone tell me what I'm doing wrong? Can someone show me how to capture the point when a downward trend changes to an upward trend? Or, the point when the colors change?

.

Thanks!
