I think it would be useful if each T2, T6, and T8's volume and value were accessible via marketVol() and marketVal() from tick() in TICKS mode. Same goes for live trading.
If necessary, set a flag to enable it, set(TICKVOL) and set(TICKVAL). (I assume Zorro would need to allocate more memory.)
Could someone with access to Zorro S try that out? I haven't gotten it yet but want to make sure that I can access volume in each tick() via marketVol(). Even if it works in backtesting with .t6 data, how about the broker plugins? Do any of them fill marketVal() or marketVol() with the volume of each tick?
