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
