2 price properties being equal

[skiguy]

I am trying to do a simple test for say:

if (High[0] = High[1])

and I get an error.

The = sign is obviously the problem.

I cannot find any documentation on why.

If I do
if (High[0] > High[1]) for example it works fine.

Many other more complex tests I do work.

Help

skiguy, the one equal sign is an assignment, if you want to compare for equality use the double one ==
