Re: [amibroker] Re: Range bars vs Tick bars

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Hello,

Range bars are constructed based on PRICE action , not the number of trades. The price needs
to fill the entire range for new bar to appear.
N-tick bars are constructed based on number of ticks (i.e. individual TRADES reported by exchange).
New bar appears after N trades taking place.

Best regards,
Tomasz Janeczko
