You will not get a cumulative effext by referencing the variable
within itself like this
Result1 = Ref(Result1, -1) +
Iif( Higher, Iif( Close > Open, 1.5, 1),
Iif( Lower, Iif( Close < Open, -1.5, 1), 0));
If you do not want to use loops which is far better you could try
this. From what I can see your results will be different because you
ahve added a different value for result1 with the added conditions and
values
Result1 = cum(
Iif( Higher, Iif( Close > Open, 1.5, 1),
Iif( Lower, Iif( Close < Open, -1.5, 1), 0)) );
you could also write this
Lower = (Low1 < Low2[0] AND High1 < High2) OR
(Low1 < Low2 AND High1 == High2);
as this (also removing the [0] as this will only ever use the value of
the first bar of the array)
Lower = (Low1 < Low2 AND High1 <= High2) ;
