I remember that an every-tick run function was implemented in an early Zorro version - but I think this feature is no longer supported, as apparently no one found any use for it. But if you can give me an example for what purpose an every-tick run function could be used in strategy testing, we can certainly re-implement it.

The shortest bar periods I've seen in serious strategies were M5, but on those short time frames the prices are mostly noise and systematic trading is difficult. Most profitable strategies use H1, H4, or D1.
