Okay. I managed to finally solve the problem, for anyone that's interested. It's always something ultra simple. I had my xo and x1 values interchanged. This works:
Plot(C, "Close", colorBlack, styleThick|styleDots);
Plot(H, "High", colorBlue, styleLine);
Plot(L, "Low", colorRed, styleLine);
// Any time that the current Close is lower than the *Low* of 5 bars ago, then plot a
// red dashed line between those two prices.
fb = Max(Status("firstVisibleBar"), 5);
lb = Status("lastVisibleBar");
Low5 = Ref(L, -5);
LineLow = Null;
for ( i = fb; i < lb; i++ )
{
if( C[i] < Low5[i] ) //
{
LLow = LineArray(i-5, Low5[i], i, C[i] );
LineLow = IIf(!IsNull(LLow), LLow, LineLow);
}
}
Plot(LineLow, "LineLow", colorViolet, styleDashed);
