Romi,
I assume that by "subtract[ing] the 'close' of a condition",
you wanted to ask 'value of a variable while some function
evaluates to true'. The reason for such rewording of
your question is that conditions return true or false,
and cannot be subtracted from numeric values.
You could say:
vars: MyCondition(false), MyVariable(0) ;
{ some code goes here to set myCondition}
if MyCondtion then
plot1(myVariable - myVariable[7] , "something");
Array referance [integer] is about as fast as you can get in EL.
Notice that you do NOT need currentbar because every bar
is a currentbar while it is being evaluated.
The index reference [ ] allows you to point back in time
using a RELATIVE addressing scheme, relative to currentbar
so it is not necessary to name it.
You may want to set the plot1 properties to POINT.
(There is also NoPlot function, but use only as necessary
since it can be slow.)
By the way
momentum(myVariable, 7)
{assuming you are using 7 bars} produces the same result,
and at equal speed.
