Whilst I trade from calculation, the many years studying price charts tell you many things and this the most obvious (but maybe the least realised): Market waves should be wavy.
Look at the trajectory of price from around last December, it's practically straight and the range of the channel is very tight. A rate-of-change indicator (whichever you use) will show this trajectory is waning, and last couple of days have shown the first distinct elliott wave on a small scale. This has now retraced itself, and this also coincides with the price level last April/May time.
Again, I trade from calculation, but the signs are interesting. Have to wait and see.
