Although the ASX 200 (now at 6475) still has the potential to get to 6800, the current uptrend doesn't seem trustworthy anymore and it might be more prudent taking your profit.
The monthly chart shows a pattern that could be a giant wave 4 unfolding with an a-b-c. Wave b, made of 5 waves up (quite unusual as there should be 3 or 7 waves up), is almost complete. If this is correct, we might be close to a major top.
Note the theoretical target at 6680-6750.
The weekly and daily charts shows that the ASX 200 unfolded an uptrend that is suspiciously similar to the-fifth-of-the-fifth, meaning that we might be really close to a top due to the completion of all the major and minor fifth waves.
Finally, the 4-hour chart displays a lot of dangerous reversal candlesticks as well a declining volume.
