Will-spread index and S&P500

I was wondering if anyone read Larry Williams long term secrets to
short term trading. In the book he talks about "will-spread index". I would
like to use this in the forex market. I know this pro trader who uses this
all the time on the eur/usd with the S&P 500. So if the euro/usd is 1.5 and the S&P 1800, the index would be 1,5*1800= 2700.

Is there any way to get this indicator on metatrader?

Thanx guys

Hi

Your thread was some time ago, but here is the indicator for MT4.

Thx, but already had that one. It doesn't work tho, the code is wrong.

What is wrong with the code

That is a problem. I don't see anything wrong with the code.
