You have to set Start/EndMarket explicitly to the times you need, or Zorro will use default values. You better do it for most of the vars yourself, not to waste time debugging unexpected results.

Doing this, you should keep in mind that:

1) Start/EndMarket are in "local market time" (while vars like StartWeek/EndWeek and Zorro's internal time are UTC)
2) setting StartMarket>EndMarket (e.g. start:1705- end:1700) which is the case for FX and futures - will not work out of the box. You will have to code around.

3) values you specify in these vars are EXCLUSIVE of that time, i.e. setting EndMarket=1700 will NOT include the bar ending 1700.

4) StartWeek/EndWeek work in 1hr increments.
