Autre argument intéressant glané sur un forum US :
I prefer volume charts, though I did AT
one time use tick.
I think of it like a punch.
Tick chart is like a jab, just one pop predicated on price. If you set your tick value high enough you will capture a lot of jabs which is more telling(painful) than a fewer number. The jabs are never consistent in force or speed per
se, so it can be misleading as to the true nature of the guys power in his strong hand(underlying market interest).
Now with constant vol charts you have a better idea of the "weight" of the punch and couple with the consistent nature of the vol level, you can get a sense of the guys power(bidding/offer urgency) via time.
So when your cvb chart ramps up/down quickly you know that it is an intentful punch with power behind it. Whereas with tick, and time it could be anything, thin market, market maker
bullcrap, news, bad print, or a real move. Plot the 3 charts overnight on one of the emini family and see which one is more readily discernible as to nature of the move.
Its harder to play games when their size is on the table and cvb makes the "trend" if there is one, more discernable. But whatever works for you, works. Nothing wrong with minute bars. If you are profitable stay with it.
ProfLogic(among others)has written volumes
on this. Good stuff and well worth a re-read
As far as candles vs ohlc, I like the visual of candle and my feeling is if you understand them you can get an almost emotional sense of the market particpants. However, something about the hash marks of ohlc gives me better picture of price and thats what I trade along with vol and time.
