Calling tops in a massive uptrend has caught me out a number of times but I can't help looking at this chart and thinking that it needs another leg down to complete a correction. The massive leg down from the beginning of the year looks a clear 5 wave move to me (impulsive) while the move up from March looks corrective (to me at least). Lots of fib measurements all zeroing on at the 2600 level so lets wait and see......
