After return to trading pick new things:
Price trends is testing and establishing of boundaries
Spotting major trend is more important than timing
When price has problem hit TP trend weakening
Like other trading concepts, applied alone they probably useless. Applied together with collective knowledge they can increase edge.
Latest observation:
Price like to retrace to breakout/breakdown price
It happen so often across timeframes there must be some way to use this idea profitably. Maybe market give second chance to enter or exit. Maybe testing price level for confirmation. Dunno, to chew.
Updated 20th Dec:
Testing happens in normal or indecisive market.
In runaway conditions, price can breakout/breakdown successfully without retracing to break level. And never look back again.
