indicator based on WTI and USD Index

Hi all
Is there a code that could let me create an indicator based on WTI, which could detect automatically the end of the contracts (rollover) and swith when the rollover is over for the available contracts?

The purpose of this question is because i'd like to "improve" the current USD index by adding WTI.
In fact, USD and gold are no longer well correlated. Apart frrom the big movements of the USD INDEX WHICH then correlate with the direction of GOLD especially to boost Gold going north.

In contrary, WTI seems currently to be the best.

I have no idea concerning the Brent. My 3 brokers did not give me this possibility.

Either get a broker which enables you to trade WTI on mt4 (i know markets.com for example does), or get a live price feed from internet and read the data from there. I believe Excell has some api which allows to get data from yahoo finance live. Might do the trick.

Anyway, #1 is the easiest

Hi
I already have Fx accounts on 3 different Brokers, and i already trade WTI.
My question was especially on how to incorporate WTI in the dollar index (could replace for example Kiwi or could be added like JPY).
Concerning trading Brent, i don't think it's a problem as the prices of Brent move like WTI, the only difference is the price. Brent seems to be 15$ more expensive than WTI.
