hi dewi141,
welcome.
have looked at p/f. rejected them fairly early on.
they are good at identifying support and resistance, by the way they are constructed.
but you lose the time element. (how long it took to rise, and how long it took to fall, etc )
there is too much info that is lost, in comparison to candlesticks.
do you use them? if so, hope you can add your dimension with a few calls and analysis.
