If the future exits from the particular bar in question then you get a value
If the bar is on or after the 4th to last day of the data, then a 4
day future does not exist
If the bar is before the 4th to last day of the data, then a 4 day
future does exist
However I cannot see any real value to using future values unless your
signal references that condition as far back in the past as you look
into the future for that condition. This forward looking would I think
generally be used for finding swing points where the pivot does not
exist until after the price has retraced.
eg
Condition = ref(occurence,4);
Signal = ref(condition,-4);
