WriteIf is working AS DOCUMENTED, was: not working as I expect

There is no array of strings in AFL

When scalar becomes an array, aka. type coercion in AFL

Does AFL support character arrays? var1 = 5; printf("%g\n", var1[ 0 ] ); // even though var1 is scalar you still can treat it as array var1[0] = 6; // now var1 becomes array (because of assignment of individual element) var2="Sell"; var2[0] = "Buy"; // <<< type mismatch var2[1] = "Sell"; var2[2] = "Buy";

But you may use AddMultiTextColumn to output string on array in Explorer.

Version(6.20);

IFU = C > MA(C,20);

Filter = 1;

// if IFU returns 0 or 1
AddMultiTextColumn(IFU,"Down\nUp", "Index", 1.3, IIf(IFU,colorGreen,colorRed), 2, 40);
AddColumn(IFU,"IFU",1.0);
