You are close, you just need to initialise the variables before the
loop rather than inside it, and define the X as an array. Inside the
loop all bar values of X[i] will be passed to the code after the loop,
by using just X only the last value in the loop of this variable is
passed to the code after the loop
DN = DateNum();
X = 0;
for( i = 0; i < BarCount; i++ )
{
if (DN[i] < 1080101) x[i] = 4;
else x[i] = 0;
}
Plot( X, "X", ParamColor("Color", colorBlack ), styleLine );
and just to confuse the issue, because X is pre-defined as zero you
can simplify the loop a bit
DN = DateNum();
X = 0;
for( i = 0; i < BarCount; i++ )
{
if (DN[i] < 1080101) x[i] = 4;
}
Plot( X, "X", ParamColor("Color", colorBlack ), styleLine );
but then you really do not need a loop for this simple array variable anyway
X = iif(DateNum() < 1080101, 4, 0);
Plot( X, "X", ParamColor("Color", colorBlack ), styleLine );
