Subtracting from a double

[lifzgreat]

I want to subtract 2 pips from a low. How do I do that?

I have

MIN(Low, 3)[0] - 2 * TickSize

but am getting the error

Operator '-' cannot be applied to operands of type 'string' and 'double'

That looks correct. Are you sure that your error is coming from that line in that indicator? Maybe you could post a snapshot of your error screen ?

I feel silly. I had that code in the middle of a string w/o enclosing it in parens. I changed that and now I have no error. Sorry!

Print("SL should be " + (MIN(Low, 3)[0] - 2 * TickSize));
