I have tried both bars & candles. Both are good, but I prefer candles .... I think it is my failing eyesight.
As to the arguement of the candlebody masking the stalk.I think that I can safely say ,once your stops have been clipped by the little buggers a couple of times, the stalks will have gained your utmost attention.
I trade forex futures and I colour my candles to change colour once the 18 day pricebands have been breached. It reminds me to take the current direction seriously and maybe let the 1st Turning Point pass before taking a contrarian trade.
18 PC is not my only trendy notion, but it does attract my attention.
