short answer is no.
Lomng answer is yes(ish). You can set alerts on the straix products and they track their repsective indices, so this works but for one potential problem. An alert only triggers when there is a trade, so while the satrix product may move below/above your alert it will only trigger when a trade happens above/below.
What you can do is set the system to send you index levels during the day. Go to My detailed watchlist and click on daily email/sms updates. The index needs to be in your watch list, select it and then delect the times/day you want the sms/email. Remember we will charge 25c per sms.
