Ralph,

For *very* actively traded instrument 100000 ticks indeed
may span 1-2 days. To cover longer period I suggest
to switch to 5-second mode. It gives you 720 bars per hour
and greatly increases speed of charting.

I can also increase the limit of 100000 bars in the next beta
(this is soft-coded limit) but note that AmiBroker (and any other app) will
slow down very, very much if you try for example to chart one million of bars.
So it is anyway not too good idea to generate charts from that much data.

5-second mode is much better choice.

Best regards,
Tomasz Janeczko
