Hi Tom,
I don't use a formula. Every market(stocks, futures and Forex) works off support/resistance of which I am sure you are aware of. I have study the markets for eleven years now and I found a different way to see these S/R areas. The hard part is that it is in every time frame and its not always horizontal. The daily time frame is usually the strongest. It takes awhile to understand what the market is telling you by the way it opens every day. I'll give an example- The market opens by gapping up and then it stops and goes down. If you know the daily support/resistance areas you can see that it jumped up to a resistance number,( sometimes it penetrates it) bounces and goes back thru the opening going down to a support area. This is a sale day. The market was still up for the day because it made a higher high ( keeping the trend intact) it just closed down. Pardon me for rambling. As you can tell writing is not my best suite. I will post some support/resistance numbers on a couple markets and will try to explain what happen the next day in that market. Remember the smart money knows whats going on in the markets they trade. Don
